Erasing CDs By Using 150,000 Volts of Electricity

Data Storage 242

ryzvonusef writes "One enterprising individual has created the most secure way to wipe out Compact Discs, by using a step-up transformer and creating a 150,000 Volt pd, whilst a CD rotates in the middle. The sparks arc through the metal in the CD and evaporates it, ripping it all off as the CD rotates. The CD is rendered transparent and unreadable. This may be the most secure method to remove data on conventional recordable CDs used in offices."

In The Ghetto, 01-10. (-1)

In the Ghetto Part I

It was pitch-black in the roach-infested double-wide trailer. All was quiet except for the gurgling sound of an infant, shut away in its own room.

The floor creaked as a mass of flesh made its way to the infant's room. The door slowly opened, creating a growing triangle of light on the floor. The infant coughed and gagged and began to cry as it was overpowered by the horrid stench.

"It's time to suck on daddy's special pacifier, Marticock!"

As the door creaked shut, the whale in the master bedroom wept into her pillow. What kind of life was this for her precious little Marticock?

In the Ghetto Part II

Reza sat at the kitchen table, her cigarette smoke blending with the steam rising from her coffee cup. She took a sip of coffee and adjusted the rollers in her hair. She rubbed her eyes, which were still puffy from crying into her pillow all night.

Vlad shuffled into the room, wearing nothing but his briefs and a stained t- shirt, "hey you fat, pig, how are you this morning," he burped.

"Vlad, we have to talk."

"What now, fat-ass?"

"It's about Marticock. You have to stop molesting him... I think it will make it harder for him to make friends later on..."

Vlad slammed his fist onto the table, causing Reza to jump. She farted.

"You're not supposed to think, bitch! You're supposed to be making me breakfast! Where is it?!"

"Vlad, please..."

"Remember when we saw the Matrix Reloaded last weekend? THAT'S the style of Martial Arts I practice, bitch. You're about to get a FREE LESSON!"

Reza rose from her chair, causing it to fall over and ran - as best she could - into the bedroom to cry again.

"Fucking bitch," Vlad farted.

In the Ghetto Part III

Vlad sat on the living room couch, the cushions torn and vomiting foam from their inner core as he bounced up and down in excitement. He screamed at the television, as he shook his fist at it, sending Budweiser spilling out all over the floor.

"Come on, you goddamn white boy, if I wuz in there, he'd be dead now. Let's see some goddamn wrestling!"

Vlad didn't notice the doorbell ringing and continued screaming obsessively at the television as Reza bounced through the room to open the door.

Reza stood at the doorway in a sheeny, purple, see-through nighty, smiling at the black couple who greeted her, "hi I'm Reza! You must be Pedro and Florence from the personal ad..."

As a commercial flashed onto the television, Vlad turned to see what all the comotion was about. He recognized Pedro in the blue cathode-ray glow, "hey DOOOOOG!"

Vlad hopped from the couch, emitting a spurt of gas as he did so.

Pedro and Florence, who was holding a fat black child with curly hair, entered the dingey apartment. Vlad and Pedro high-fived each other and then Pedro began to rap:

This is Pedro G
Gangsta P
Sippin' on Hi-C
Smokin' PCP
Smooooooth Nigga

Vlad began to break-dance to the off-the-cuff rap. Farting with each bend of the leg and twist of the waist.

Oooooooh. A little Mastah B on the Bonus T
Got it goin' on girl
Droppin' Baby Marticock on your ass, Byatttch

Vlad and Pedro laughed heartily and butted guts.

"You ready to do some swappin' V-Dog," Pedro drooled. Reza grew wet with the suggestion.

"You bet I is, bro," Vlad replied eagerly. He trampled off into the other room, much to Reza's confusion.

In no time at all, Vlad returned holding Marticock, gurgling and farting. Pedro took his child from Florence and exchanged him for Marticock.

Reza frowned and shook her head, "no, no, no!"

Vlad and Pedro laughed as Reza and Florence ran into the bedroom to weep.

Vlad grinned as he removed the black child's diaper, "this is gonna be good! I never cornholed me a nigra before!"

In the Ghetto Part IV

Reza gazed into the bathroom mirror. The sense of despair overwhelmed her. Vlad's nightly visits to Marticock the Gurgling Penis Socket had been torturing her for weeks. She hadn't slept at all and it was beginning to show. The bags under her eyes were dark and full. Her eyes were red from constant crying. She even thought she could see some wrinkles appearing in her puffy face. She had to do something.

She opened the mirror to reveal a series of shelves. She found Vlad's razor and took it with her shaking hand. She closed the mirror again and stared deeply into her own eyes. Did she really want to do this? Was this the only way out of this mess? She heard the front door slam, followed by a loud belch and fart. Those three sounds that used to bring her so much comfort. She decided she must end it now.

In the living room of the double-wide, Vlad threw his empty Budweiser can onto the floor. He plunged his hand down the back of his pants to fish desperately for a ball of crust caught in his anal hairs that had been plaguing him all day. He moaned deeply as he plucked the nugget from his anus, taking along a few assorted hairs with it.

"Hey, bitch, where's my dinner?" Vlad screamed.

He heard a crashing sound in the bathroom, followed by a thud and a large splash.

"Fucking cunt," he spluttered.

Vlad trudged into the kitchen and liberated another Budweiser from the bottom shelf. He opened the can and drank half the contents, signifying his approval with an enormous belch. Suddenly, he heard more splashing and riff-raff in the bathroom. He wallowed across the room and into the hallway and opened the bathroom door.

Vlad was shocked. Reza was laying in the tub, completely bald. Not only were her legs hairless for the first time in years, but so were her armpits! The hair on her upper lip had been completely removed, as well as the ratty hair that covered her scalp. Vlad's mind reeled. How could she have managed to reach her legs with all of that lard in the way?

"Look, Vlad! I am Marticock!" Reza said with a hint of hope in her voice, "you can molest me now!"

Vlad farted, "Marticock?"

Reza nodded, "Ummmm-hmmmm!"

Vlad shook his head. He noticed the comforting gurgling sound in the room down the hall, "Marticock..."

Vlad turned and stumbled down the hallway to Marticock's room. He opened the creaking, paper-thin door, "daddy's home, Marticock! Open wide!"

Reza cried so hard that she deficated in the tub.

In the Ghetto Part V

Vlad farted.

It was a plump, furry fart with a long wet tail. Vlad couldn't tell if the vibration at the end of the fart was just particularly chaotic or if it had left a moist surprise for him. He reached down the back of his underwear to feel around and discovered some moistness on his underwear. He sniffed his fingers and his mouth watered at the unusual scent. He wiped his fingers dry using his t-shirt.

Vlad knew this would be a good day.

In the Ghetto Part VI

Vladinator's bulk took up most of the sidewalk as he waddled slowly towards his destination. Pedestrians jumped out of his way into oncoming traffic to avoid being trampled. Finally, panting heavily and with a river of sweat running from every gland, his three-block walk came to an end. He found what he had been searching for. He let out a satisfied fart as he looked at the sign:

Chicago Unemployment Office

Inside, a long line of vagrants and lost souls stood waiting in front of the counter. It smelled of piss and vomit. Scott Lockwood squeezed himself through the door, and the smell worsened tremendously.

Vlad looked at the dozens of people in line ahead of him, contemplating the long wait he faced before he could get his check. "No, this won't do," he thought. "This won't do at all." His face took on a grimace of deep concentration, followed by an intense sigh of relief.

It was silent, but deadly. One by one, his fellow unemployables screamed as they felt the burning in their lungs. Some began to retch. Within a minute, everyone had either fled in terror or lost consciousness. Vlad was now at the head of the line! "Much better," he thought to himself.

He waddled up to the counter and smiled a yellowish smile. Standing there was a cute teenage girl wearing a standard-issue gas mask. But Vlad had no interest in girls. "Give me mah check!"

"Your name please, sir?"

"William Scott Lockwood III. Hurry up, cunt!"

"One moment." The girl tapped buttons on her computer, and then frowned at Vlad. "I'm sorry, sir, but your Unemployment coverage has expired. It looks like you've made no effort to get a job for over two years, so we have to cut you off."

Vlad's face turned red with rage. He farted an angry fart. "WHAT?! I'll fucking kill you, bitch!" Vlad dropped into a sad parody of a martial arts stance. The sound of his pants ripping was followed immediately by another kind of ripping. The counter-girl's gas mask began to melt away.

She pushed a button, and a plexiglass barrier dropped between her and Vladinator. "I wouldn't try that, sir."

Vlad fell on his ass, exhaused from his attempt at moving his body. A farting sound was heard as he landed. He began to cry. "Why would you do this to me? Is it because I is black?"

"Pardon me, sir?"

"Whitey is just trying to keep the Black Man down! Everywhere I go, nobody gives me a chance, because of the color of my skin! A nigger just can't make it in the world today because of all the prejudice and bigotry!"

The girl looked at him with sympathy and concern. She pointed to a mirror on the wall next to Vlad. Vlad turned his head to look, and then screamed in terror at what he saw.

"WHITE! I'm white?! NOO!!"

The girl nodded.

Vlad continued to blubber, "you mean, the white man ISN'T keeping me from getting a job? The white man ISN'T keeping me from having a good life? All these years I thought..." He trailed off into incoherant sobbing and farting.

The girl shook her head sadly. "Mr. Lockwood, there IS a white man keeping you from having a good job and a good life. That white man is yourself."

Vlad felt shame as his bladder emptied into his pants, because he knew it was true.

In the Ghetto Part VII

Vladinator slowly waddled home smelling or urine and flatulence after his unsuccessful trip to the Chicago Unemployment Office. Tears and mucous ran down his face as he sobbed about the sad state of his life. Even knowing that baby Marticock would be there in a skimpy diaper waiting for him at home was no comfort now. He was miserable and he wanted to die.

Not wanting to go home and face his family without his unemployment check, he turned off the sidewalk into a narrow alley between two tall buildings. Then he realized he wouldn't fit through the alley, and went back to find another one that was wider. It grew dark as he walked through the forgotten back-alleys of Chicago's filthy slums.

Suddenly, Vlad heard a gun being cocked. A voice behind him barked out, "don't move or you're a dead man!"

Vlad saw that a homeless Negroid mugger had pointed a gun at him. "What do you want from me?" Vlad whined.

The homeless Negroid mugger responded, "You have two choices. Give me all your money, or I'm going to rape your ass. By the way, I have AIDS."

Vlad stammered, "B...but I don't have any money!"

"I guess I'm going to have to rape your ass, then," the homeless Negroid mugger replied sadly.

"Yes, well, I guess that's the only other choice, now isn't it," Vlad quickly replied.

"If that's how it has be... well, okay. I'm going to rape your ass now."

So he did.

Afterwards, when the homeless Negroid mugger had left, Vlad removed the large wad of money that he'd hidden between two rolls of his stomach that morning, and took a deep whiff of it.

"I am SO clever," thought Vlad.

In the Ghetto Part VIII

Vlad sat at the kitchen table finishing off a case of Budweiser. The metal table, with its peeling yellow paint comforted Vlad. He belched heartily as he admired his vinyl and plastic life in the double-wide. The only fly in Vlad's ointment was the elephantine woman who was cowering in the bedroom closet sobbing at Vlad's approaching Marticock Time.

As much beer as Vlad had consumed, he still could not alleviate the burning in his pants. His penis was chafed and red from its constant attacks upon Marticock's ass. Vlad loved the tightness of it, but it did have drawbacks. He shoved his hand down his unzipped pants and worked his hand around the layers of lard until he found his penis. He rubbed it carefully, sending thin rolls of dirt-encrusted skin flaking into his pubic hair. His penis burned intensely as he rubbed away the scabs to leave large areas of tender, pus-coated sores.

Vlad's penis twitched to attention as he manipulated it. Vlad downed the rest of his beer and tossed the can onto the living-room couch - the back seat of the Chevy van which was up on blocks in Vlad's front yard. It was Marticock Time. Vlad waddled to the refrigerator and fished out a tub of I Can't Believe It's Not Butter. He plunged his stiffened penis into the margarine, causing a thimble-sized indentation in the otherwise smooth yellow surface. Vlad massaged the margarine into his penis until it was nice and buttery.

Vlad belched, "Wake up Marticock! Here cums daddy!"

The mating call caused a spasm of nervousness to clench around Reza's bowel. She farted loudly as she quivered to each heavy thud of Vlad's footsteps. Her crying was matched only by the screaming of the molested Marticock.

In the Ghetto Part IX

Reza's face was cast in stark shadow. Marticock gurgled and drooled as she looked upon his paleness, lit only by the blue moonlight filtering through the window. Reza heard an enormous explosion in the bathroom and knew that Vlad would be there for a long while. She stared at the drooling Marticock with a grimace on her face. This was the first time that she actually looked upon her baby son with disdain. It was all Marticock's fault. She hadn't had sex since he came spilling from her substantial gut. Before Marticock, Vlad had treated her with respect, only beating her when she deserved it, and had made her feel like a real woman for the first time in her life.

Now, it seemed that all Vlad could do was drink beer, emit gasses and molest his son. He had even managed to land a job shoveling cow dung at the local slaughterhouse, only to get fired the next morning for being late - late because he spent too much time probing the tiny anus that lay before Reza. She frowned even more. How could it have come to this? For nine months, she had planned a wonderful life with her husband and their child. The reality was quite different.

A small, thin stream of gas escaped from Marticock's anus. Marticock's flatulence was a point of pride for Vlad and he often enjoyed a burst of cool gas on his penis while molesting his son. But the spurt of noise only reminded Reza of the times before Marticock. When Vlad would violate her as no other man could, with his farts causing him to vibrate like an electric dildo. That was the last straw for Reza. She let her robe slip from her body as she undressed Marticock.

Vlad squeezed out the last few drops of liquified feces from his gut. Satisfied that he had completely expunged the wastes that lurked within, he reached around the back of the toilet for the golf club. He wrapped a thick mass of toilet paper around the club and squatted on the floor, using the club to wipe his ass - the only way he could reach himself through the vast rolls of lard.

Vlad pulled his yellowed t-shirt down over his waist and headed for the nursery. Nothing crowned a relaxing defecation like a visit to Marticock. He quickly opened the door to Marticock's room and flipped on the light. Vlad farted in shock at the sight before him.

Reza was squatting on the floor, her paper-white ass cheeks protruding like two enormous dumplings, pocked and wrinkled and bursting with cellulite. Marticock was hanging from her vagina, his head fully wrapped in the rancid lips, which were stretched so wide that they had begun to tear. Blood and pus oozed from the yeast-infected vagina all over Marticock's body. Vlad stared, his mouth agape, as Reza held Marticock's legs and shoved him, as hard as she could, back into her womb.

As Reza shoved on Marticock, his legs spread apart, causing his anus to be plainly visible. Vlad grew excited and could not control his desire for little Marticock. Vlad ran over to Reza and shoved his scabbed penis into Marticock's anus. With each violent thrust, Marticock was shoved further into the mounds of disgusting lard. Vlad licked Reza's blood and pus from Marticock as he ejaculated a few spurts of semen onto his own pot-belly.

All of the commotion had caused Reza to become extremely excited and she exploded with an orgasm - an orgasm that had been months in the making. The force of the release caused Marticock to shoot back out from her vagina. Reza fell backward onto Vlad and the three Cockwoods lay in a giant, pale heap on the floor, farting with satisfaction.

In the Ghetto Part X

The orange vinyl of the couch stuck to Vlad's pale, massive leg as he guzzled another beer. Vlad had "made" the couch from the back seat of his Chevy van after the bank had repossessed most of his belongings. The seat was not needed on the van anyway, since it had been up on blocks in the front yard for the better part of a year. Vlad farted and enjoyed the unique sound of the vinyl flapping against his fattened leg due to the vibration of the escaping gasses. The couch was the only seating in the living room of the double-wide and so Reza was usually consigned to the floor. Vlad never let her sit next to him, claiming that his massive gut "needed to breathe".

Reza sat on the stained yellow carpet wearing a see-through purple gown. She sat with her legs spread open, exposing her red, infected vagina. The massive flaps of flesh that were her labia hung from her crotch and melted into a heap on the floor, still stretched and bruised from her attempt to reinsert Marticock into her womb. Various milky and pungent substances oozed from the massive black hole onto the floor to create a sticky white puddle. Carter, the Lockwood's dog, mosied over to the puddle and lapped it up as Reza belched up a portion of the evening's meal.

Vlad dug his fingernails deep into the flesh surrounding his anus and scratched heartily, oblivious to the tiny details of Lockwood life that were playing out around him. His meditations were, however, interrupted by a banging on the loosened screen door of the double-wide. A pang of excitement shot through Vlad's bowel and expressed itself as a thunderous burst of flatulence. He tried to leap up from the couch, but the hold of gravity upon his massive body slowed him significantly. Eventually Vlad made it to his feet and trudged to the door. He opened it to an extremely large man, with a flabby gut hanging all the way down to his knees.


"Hey, Vladdie," the gruff voice chortled, "give me some sugar, son..."

Vlad melted into the massive, hairy arms and inhaled deeply to savor the comforting scent of week-old sweat. Poppa rubbed Vlad's back with his dirt- encrusted hands, massaging his way down to Vlad's butt. He took one cheek in each hand and squeezed passionately. Vlad moaned with pleasure and placed his lips firmly on his father's. Vlad partially opened his mouth, and stuck his tongue out, past his missing teeth and into his fathers mouth.

Vlad could taste the residue of tobacco his father had been chewing and this excited him even more. He moved his hands down his father's back and into the back of his pants. Vlad carressed his father's bare ass, exploring each pock and wrinkle with his fingers and massaging his anus. Vlad's penis swiftly snapped to its full 1 inch of attention as he explored the moist, tight anus of his father.

"Vlad! What about me, damnit, " Reza screamed.

Vlad pulled away from his father and shook his head, "oh yeah, follow me, Poppa."

Reza smiled with a glimmer of hope which was quickly smothered as Vlad walked uncaringly past her, followed by Poppa. Reza began to sob uncontrollably then screamed loudly as Poppa stepped on her bruised labia. She rolled over onto her massive stomach and cried and screamed as she pounded the dirty floor of the double-wide.

Vlad motioned his father to Marticock's room, "I figure we can start out with me in Marticock's ass and you in mine," Vlad said eagerly.

"Now wait a minute, son! I want a piece of that tight little ass too!"

Vlad's eyes brightened with hope, "does that mean you're gonna let me in the back door this time, Poppa?"

Poppa smiled and patted Vlad on the back, "you betcha, son. I've been lookin' forward to this for a loooong time. Three generations of Lockwood, doin' it the Lockwood way!"

Vlad farted with excitement.

Re:For those with less sense and less money (1)

ZosX (517789) | about 3 years ago | (#35874054)

how is anything hard on the magnetron? all it does is emit energy, which the metal readily soaks up and superheats. The real danger is more catching the microwave on fire than anything.

Re:For those with less sense and less money (3, Interesting)

spun (1352) | about 3 years ago | (#35874236)

The thinking goes, the magnetron is basically an antenna, right? So it can pick up as well as transmit energy. If an electric charge builds up and arcs stright into the magnetron, it can blow up. Or something like that. I've never seen it happen, and I've blown up a lot of stuff in microwaves over the years.

A quick google search for "blow up the magnetron" turned up this answer from a microwave engineer:

2. metals in the microwave oven - they will not destroy the oven or cause it to blow up. I routinely heat my coffee with a spoon in the cup. I also did the definitive early research on this in the late 70's and early 80's. But it is possible for metals to arc (spark) under certain conditions. This can be dangerous especially with things like metal twist ties and steel wool. Also, things like the metal trim (silver or gold) around the rims of fine china is dangerous in that the dish or cup can easily beak or shatter - but this due to the trim not being perfectly continuous like a wire that would carry current, Instead the trim has microscopic gaps and that can cause micro-arcs and temperatures exceeding 1000 F locally.

Don't you just love the Internet? We get to be wrong more often, but not for as long.

Re:For those with less sense and less money (2)

Phibz (254992) | about 3 years ago | (#35874400)

Metal isn't always bad in the microwave and certainly won't blow it up. Many modern microwave food containers have a metal grid in them to diffuse the microwaves as they cook the food.

Although the vaporized foil probably isn't good to breathe or eat.

Re:For those with less sense and less money (4, Informative)

v1 (525388) | about 3 years ago | (#35874372)

It's not an intuitive thing, don't worry you're not alone in not immediately seeing the problem.

A magnetron is a kind of RF (radio frequency) transmitter. It converts electrical energy into radio energy. This energy leaves the magnetron and bounces around inside the microwave. The frequency used makes it tend to interact with water molecules, and heats them up, changing radio energy into heat energy. And that's what heats the food. (note that foods with significant water content heat best)

The microwave is tuned just like an antenna is tuned, to maximize the use of energy. Energy the magnetron takes from electricity has to go somewhere. Energy sent into the box that isn't absorbed and converted to heat is reflected back to the transmitter. This is aka a "standing wave". The "Standing Wave Ratio" tells how efficient the energy transfer is.

A high SWR means a large percentage of the input energy is being reflected, and back to the transmitter where it must be used and so is converted into heat. Transmitters expect some of this because the conversion isn't perfect to begin with, but they're not designed to handle a LOT of additional energy to dump, and will overheat. Very high frequencies like magnetrons use are especially inefficient to start with, and so they're usually designed to cool heavily, with fans and fins. The heat you feel coming out the back of the microwave is NOT heat from the food, it's the waste heat off the magnetron. Adding too much to that waste heat can overheat and damage the magnetron, sometimes very quickly.

So, if you put a substantial chunk of metal into a tuned cavity like a microwave oven, it will interfere with the transfer of energy and cause a higher SWR, which can damage the magnetron. Running a microwave without anything in it is not recommended for the above reason, but adding metal into the mix makes matters worse. Placing nothing in the cavity besides a substantial piece of metal is about as destructive as you can be. The denser the metal, the bigger the effect.

Re:For those with less sense and less money (1)

Hultis (1969080) | about 3 years ago | (#35874264)

I've done it as well, without a problem. However, I think it's easy to damage the microwave if you keep it running for too long, since the CD doesn't contain a whole lot of water that can absorb the energy. Wikipedia has a section explaining it:

"Another hazard is the resonance of the magnetron tube itself. If the microwave is run without an object to absorb the radiation, a standing wave will form. The energy is reflected back and forth between the tube and the cooking chamber. This may cause the tube to 'cook' itself and burn out. Thus dehydrated food, or food wrapped in metal which does not arc, is problematic without being an obvious fire hazard."

Re:For those with less sense and less money (1)

Buy a cheap microwave just for this purpose. I'm guessing a 150,000 volt transformer is going to cost you more than $70 (and probably weigh a bit more than a small microwave too).

Well this doesn't really "Erase" the data either. The pits are still in the plastic, just apply a new reflective backing and the disk is readable again.

Best is to simply break the disk up either manually or in a shredder.

Isn't the data actually stored in the plastic, rather than the metal?

So wouldn't recovering the data just be a case of putting something reflective on the back of it? e.g., placing a blank CD on top of the erased one.

Nope, the metal is a reflective layer allowing the pits in the plastic to be seen by the laser.


Depending on this top acrylic layer; it may be that depositing a new metal layer on the top of the disc will allow this to be read again.

CD-R have the data stored in the dye layer, the metal is just a reflective surface

What's wrong with just burning them? Why would someone ever want to waste 150,000 volts to erase a little bit of data on a single disc when you could erase as many as you can toss in for the low, low energy cost of a single burning log?

You have it backward with regard to the energy cost. You see you have 150 000 V * 0.001mA *25s and for a typical 1kg wood log (assuming total combustion) you have 18 MJ/kg * 1kg and according to wolframalpha [wolframalpha.com] 150000 V * 0.001mA * 25s 18 MJ/kg * 1kg = true

Beat me to it. The important surface on a CD is the "side" with the label on it. A few seconds with sandpaper does very easily solve any issues. Note - with something more complex like a dual-layer DVD, you have to destroy the actual disc to get at the second layer.

lots of ways to destroy a plastic disc with metallic coating. i kind of agree. there is the relative small risk in shreading that they can somehow reconstruct a disc, but even then they wouldn't have anything near a complete image. nope, i'd say about 3-5 seconds in the microwave is about the quickest and easiest way to nuke a cd.

Except that the data is still fine. Manufactured CD are imprinted with a mold then the aluminum is deposited on. The pits are still there just no more aluminum. You could use an interferometer to read the data.

Is this really secure? (5, Interesting)

Zorpheus (857617) | about 3 years ago | (#35874084)

Of course you can not read a CD if the reflective metal layer is removed. But the data is stored in tiny pits that are printed into the polycarbonate layer. If the polycarbonate is not damaged too much, the CD might be readable when a new metal layer is applied.

The metallic reflective layer is NOT where the information is stored, it just aids in the information retrieval. In other words, this method might not destroy the data at all. It's true that it's pretty hard to get the data back, but depending on various conditions it may not be impossible.

Indeed, I can imagine a CD data-recovery player in the future that analyzes non-reflective surfaces with high-resolution lasers or other imaging, just to recover data from aged CDs. Kind of like the laser-based record-players today. And I imagine such a player available at consumer prices.

Re:Flashy but not secure (1)

Darinbob (1142669) | about 3 years ago | (#35874516)

This is true for a manufactured CD. The data will be actually encoded using physical bumps. But for recordable CDs which are typically the only type where you care about erasing, the sparks or microwave should do a good job of messing things up.

Anonymous Coward | about 3 years ago | (#35874250)

I don't really think that method erased the data on the CD.
What happened is that the electrical charge evaporated the metallic layer of the CD. Since the real data is not burned in the metallic layer, it still available (but unreadable).

The data is stored in the polymeric layer inside the plastic, and the metallic layer function is only to reflect the laser bean.
In theory, if you can coat a new metallic layer on that electrical charge erased CD, you could read the data again.

Sure, this may be "the" most secure method, but there are plenty of other methods that fall easily into the category of "good enough" (microwaves, shredders, even breaking apart by hand). Kudos for the geek factor with all this, but realistically this is a solution without a problem.

This guy should sell this to the Government. (0)

Anonymous Coward | about 3 years ago | (#35874312)

Speaking from personal experience, I think the USA would pay around 15000 dollars for such a device. When I was in the Coast Guard, the TC's (guys who were in charge of CLASS stuff at the time) spent 2000USD for an automatic CD shredder. It had vacuum attachments to remove the pulverized dust and everything. Too bad it never worked after the first 10 CD's or so. That didn't stop the TC from buying another automatic TISCOM approved CD disintigrator. When that stopped working, the TC's just went back to the old reliable, and shredded the CD in the shredder, or took sand paper and sanded it down to the film. Hmm, 2000 USD or 0.73 USD for piece of sandpaper.

I can't imagine why we have debt issues in the USA. I also am glad we have such people guarding our nations secrets.
So if he pays of the right lobbiest, he can definately turn this into an approved method of destruction. Remember kids. Alqaida uses sandpaper, we need to use 15 KV of electrons like good USians.

CD dust. Don't breathe this.

Seriously though, I've never had anything that would be worth truly securing. I've found that simply breaking a CD and tossing it into the garbage is enough.

We actually had a CD shredder at one office where I worked. Once again, if they could actually manage to piece together multiple shredded CDs (can anybody do that?) they simply would have gotten our source code, and the opportunity to be sued by us. I think we wagered rather smartly that it was secure enough.

This does get me wondering though. What does the government do with CDs that have top... ohhh... they share it with PFCs, who leak it to the world. Nevermind.
