But that article seems pretty suspect to me. I know some OEM PCs have HDs with hidden partitions, but I doubt they'd be half the HD size. Plus unless there's a way to mask partitions from DOS, you could see what was on the HD using, say, fdisk (on a Windows machine - I dunno the Linux equivalent).
I, for one, will not be trying it. I agree with parent in detecting a whiff of bullshit.

If this is real which is doubtfull it is probably a marketing trick. The drive manufactures proably make one drive and sell it as 3 different drives in different capacities.

Actually, this is exactly what they do. The difference, however, is that the lower-end (smaller) drives are identical except that they come with fewer platters. For example, a 160GB hard drive today likely has two 80GB platters, whereas an 80GB drive probably has one (though different combinations of different sizes are of course used, depending on when the hard drive was manufactured and other factors)

In some cases, a hard drive will be sold with a greater potential capacity than its available capacity. For example, a drive with two 60GB platters may be sold as a 100GB drive, the platters having been "short stroked". This has nothing to do with the absurd technique described in the Inquirer article, and I doubt that it is possible to recover the lost space.
Hard drives are the highest precision mechanical devices that most people have in their home--moreso than processors, high-end printer heads, or toasters. They are not something that you want to physically modify.

I was really hoping for a cool firmware/bios hack to turn on unused platters or something cool... this is utterly dissapointing.

What is truly amazing is that some fool "discovered" this and actually believed he got ghost to double his HD size.

This does not in any way increase the physical disk size... this either overlaps partitions (bad thing) or creates a virtual partition inside the main one (stupid thing).

Re:Uh, no (4, Interesting)

borgasm (547139) | more than 10 years ago | (#8519070)

Well thats what they advertise...

There are lots of internal sectors that are reserved for errors. There are builtin algorithms on the disk to diagnose and correct physical errors. You just don't notice them because the disk remaps those sectors transparently.

I doubt that. I think it's more like you get what you believe you will get. If you believe you should pay more, then you will. If you don't, you don't.
You may doubt this, but it is related to one's ability to judge what defines self-fullfillment. Some people know how to fullfill their needs without spending money, others need to spend money to feel fullfillment because they lack an understanding of their goals.
I haven't paid for hardware in a long time because people are so quick to give me their supposedly outdated hardware that I can use in ways they can't even use their brand new overpriced, overheating, electricity guzzling toys.

I suppose it's possible to pack more information into the outer cylinders of a harddrive, since the data density of the outer cylinder is much lower.
The outer cylinder is a much longer 'track' than the inner cylinder but still a conventional harddrive stores the same amount of data in all cylinders.
If you calculate how much more data that is teoretically possible to pack into the increasingly longer tracks, then I suppose you will end up with numbers like the ones suggested in the article.

No way in heck can you increase the amount of storage a HDD has so drastically. I mean, the physical disks can only hold so much, and no matter what you do, they arent going to magically double or triple.

Floppy / Drill fun (4, Interesting)

Channard (693317) | more than 10 years ago | (#8518968)

This does sound suspect, but it reminds me of the trick you used to be able to do with 720 floppy disks - you could drill a hole where the hole on a 1.4MB disk would be and use it as a 1.4MB disk. Trouble was, it wouldn't retain data for very long, but it usually lasted for a day at least before the data degraded.

innocent_white_lamb (151825) | more than 10 years ago | (#8519011)

THIS method is obviously BS (to put it mildly) but back when the dinosaurs roamed the earth we could double the size (or was that 1.5x, I can't remember) of a MFM hard drive by hooking it up an RLL controller. I remember putting a full-height IBM 10mb hard drive into my 386 and making it into either a 15mb or 20mb hard drive. I used that hard drive to store and rotate Fidonet echomail for several years, as I recall.

That worked because RLL encoded the data using a different method than MFM.

This, though, is smoke and mirrors.

Re:Floppy / Drill fun (2)

Piquan (49943) | more than 10 years ago | (#8519040)

Sure, since RLL is a compression technology. You just put a hardware compression system between the computer and the drive. Completely different beast here.

Floppys used to be better.. (5, Informative)

Zurgutt (131637) | more than 10 years ago | (#8519051)

In 1994 I bought a box of 720K single-density floppies by TDK. After discovering that making this extra hole could double the disk capacity, I crudely bashed the holes in them with the end of scissors.

These floppies were used almost daily for 3 years. (no hard disks available at that time). They were reformatted countless times.

Not single one of them ever failed. About a year ago, when failed to reformat and make a boot disk from several fresh-brought floppies I digged up one of them, reformatted again and succeeded in making a reliable boot disk.

Quality of todays media just makes me cry.

Re:Floppys used to be better.. (1)

obeythefist (719316) | more than 10 years ago | (#8519112)

I've still got some at home. They weren't totally as reliable as fully tested HD floppies, but they did great and they cost less. My dad had a bench drill that made really short work of punching holes in the disks, too. You just had to get it at exactly the right spot and you were good to go. Can't see that working with CD-R's somehow.

We also used some software, forget the name now, that allowed formatting of 360K floppies to 420K, and 720K to 800K. Those were the days! I ran MS-DOS3.3! And QUEMM386.

User 956 (568564) | more than 10 years ago | (#8518979)

So either the whole thing is a hoax, or, more likely, the OS is looking at a damaged drive (damaged partition table, at least) and seeing the same partition in multiple ways. Try to write on that shiny new partition and you'll be overwriting data on the old one. Guaranteed.

Some drives are known to short stroke their platters. This raises the more serious problem of this idiocy... The problem is modern drives store important information on those hidden inner areas of their platters (firmware, disk information, reallocated bad sectors), who knows what you could be overwriting whenever you use that space. Put something down in the wrong place and the drive will never start again or corrupt data at certain sectors. It's a lottery ticket everytime you write data in that partition. That's not what I call useable capacity.

Don't believe me? Go ahead and try it. You'll lose all those Buffy episodes you've downloaded on KaZaA, and instead you'll have to spank it to the Portman pictures your mom doesn't know you have stashed under your bed.

Reminds me of the old trick in which you could turn a single-sided diskette into a double-sided one by punching a hole through one corner.

Slight problem: the diskette usually failed a few weeks later.

The trick with this hard disk "expansion" is to reclaim space that has been reserved for error correction, or which failed quality control.

It's a lot like over-clocking a CPU, with a big difference: when it fails, you can't just reboot, you lose all your data. Personally, with HD prices so cheap, it hardly seems worthwhile.

That's because you were spinning the disk backward when you turned it over. Any/all of the dirt or dust that was picked up by the jacket went right back onto the floppy disk when when you flipped it that way.

Channard (693317) | more than 10 years ago | (#8519003)

'A representative for large hard drive distributor Bell Micro said: "This is NOT undocumented and we have done this in the past to load an image of the original installation of the software. When the client corrupted the o/s we had a boot floppy thatopened the unseen partition and copied it to the active or seen partition. It is a not a new feature or discovery. We use it ourselves without any qualms' Which, having worked for a PC sales company, I can confirm is true. And certainly, while earlier models had partitions you could wipe with partition software, later PC builds had this hidden space. But the space was 1GB at most - there's no way there was the kind of 40GB plus hidden space the article claims.

This idea sucks (1)

Neo-Rio-101 (700494) | more than 10 years ago | (#8519004)

If you do this you can say goodbye to spare blocks that are remapped in case the HD finds a bad block.
If you want to risk all your data stored on your huge hard drives... go ahead and do this. Otherwise I think this is generally a bad idea.

It is definitely not a case of Hard Drive makers ripping us off either. Even though you can buy a 250GB hard drive, it will appear on the system as 231GB or something close to that due to the math that GB are calculated at, as well as the file system overhead.

So yeah, this idea sucks.

Summary... (5, Informative)

nacturation (646836) | more than 10 years ago | (#8519010)

I think posting in the "letters" linked article sums it up pretty well:

About the "recover unused space on your drive" article:

Working for a data-recovery company I know a thing or two about harddisks....

One is that if the vendors would be able to double the capacity for just about nothing, they would.

All this probably does is to create an invailid partition table which ends up having:

|*** new partition ***|
|*** old partition ***|

overlapping partitions. So writing either partition will corrupt the other. It probably so happens that whatever situation people tried it, it just so happened that the (quick) format of the "new" partition didn't corrupt the other partition to make it unbootable.

And the 200G -> 510Gb "upgrade" probably has ended up with three overlapping partitions....

You can increase some HDD sizes (2, Interesting)

GrpA (691294) | more than 10 years ago | (#8519019)

However it has more to do with manufacturers cripling the size much like the old Celerons were sometimes PIIs.

In those instances however, it often involves firmware upgrades, to remove the "crippled" firmware and replace it with the original intended firmware for the model it really was.

But the method explained sounds like a great way to generate more work for PC techs when clueless users try it... Just like using a frozen Mars Bar to let you overclock processors...

Remember MFM to RLL? (1)

osmac (24461) | more than 10 years ago | (#8519021)

Does anybody else remember using 30MB MFM hard disks with an RLL controller (or such), so that a 44MB RLL drive resulted?

I do not remmber the exact numbers, but I think it was around an 130% to 150% capacity increase.

Andre Hedrick (5, Interesting)

Anonymous Coward | more than 10 years ago | (#8519025)

The old Linux IDE guy spoke of something like this a while back. Apparently the drive vendors got sick of stocking every drive model for warranty replacement, and implemented a scheme where they could "flash" a generic drive with a specific model number and capacity. Therefore it's possible that your "120GB" drive is really qualified for 160GB but was set that way for inventory reasons.

This was on the linux-kernel list a while back, too lazy too find it. (And it's possible I misunderstood -- Hedrick is a crackpot who is barely able to articulate what he is thinking.)

This is nothing new, I just read the article, the same thing happened to my Compaq 486 when I installed Solaris Base Server 2.4.

Any partitioning program lets you do stuff like this. And, for those of us who use an operating system other than windows, we've been doing it for years.

If you want to check out something cool, floppy disks can actually be converted, many times, from SS to DS.

Parent post's link has a hardware hack for doing the same thing. Too bad it only works for Windows.

" A hard drive becomes fragmented very, very fast. What happens is that all the tiny ones and zeros gets mixed and confused, and to get back the original speed on Your hard drive it's necessary to Defragment it.

There are several of different species of software to make this happen, but the most excellent way to do it is a hardwaredefragmentation. you'll only need some basic data-mechanical-skills to be able to accomplish this operation. ...

If you have Windows on your Data machine, You'll find the OS on the top disc, you'll recognize it easily, it's much heavier then the rest of the discs. If you use Linux, then you'll of course don't need to do this operation at all... "

I thought this was going to be helpfull (5, Funny)

Zakabog (603757) | more than 10 years ago | (#8519031)

I saw the article title and I was very excited. I've bought many hard drives, and just recently I bought a 160 gig drive (was like $80 too after a mail in rebate, Fry's I love you...) and was about to buy a 250 ($110 after rebate, Fry's, still love you.) But then I figured, well if I do buy the 250, it's going to be able to hold around 200 gigs, and for some reason 50 gigs will be gone without a trace. I think there's 30 gigs missing on my 160 too, I've noticed this on a lot of drives (as drive sizes go up, so does the missing space.)

I thought this would actually let you use up that lost space somehow, you did buy the drive, it should contain the space, but it doesn't. RAM is just the opposite, you buy 512, it has 560 or so, well any ram I bought did. Anyway, is their a way to recover this lost space? Is their something I'm doing wrong? It seems to be worse in linux (but I heard that's cause it reserves space for root to access.)

Re:I thought this was going to be helpfull (1)

jangell (633044) | more than 10 years ago | (#8519048)

That's just because of the way they advertise. The space isn't hidden. They are just using fake numbers 1000 instead of the real 1024. You aren't very smart are you?

1024 vs 1000 as the meaning of k (1, Insightful)

Anonymous Coward | more than 10 years ago | (#8519072)

The problem is that drive manufacturers insist on claiming HDD sizes with a gigabyte meaning a thousand million bytes. It isn't meant to mean that, it's meant to mean 1024*1024*1024.

So you lose a few percent of capacity there.

There's also always some overhead of index tables and so forth for your filesystem, but you can't really complain about that - you kinda need it.

20GB - 1 TB (0)

Anonymous Coward | more than 10 years ago | (#8519079)

I actually had windows report my 20GB drive to be 1TB in size last week.

Of course it wouldn't install. Now the disk isn't broken, I could install linux on it no problem (disk was reported as 20GB).
A side note is I have two such disks and they both behaved in this way,
the disk a Seagate cheetah which came from a Sun Ultra 5.

Does anyone know if Sun IDE disks have a firmware that makes it impossible to install windows on it?

It isn't a bad windows CD either, it installed perfectly on another non-sun IDE disk.

No I didn't RTFA (1)

mirko (198274) | more than 10 years ago | (#8519086)

I first thought it was related to the way CDR manufacturers can now propose >800MB discs, by using some redundancy check space for storage use.
Now, above comments mentions some Norton Ghost use that trick the fat (as in "file allocation table, not as in msfat) in order to make it see more sectors as usual.
Am I right or is there definitely something "that matters" in this article ?

Four little gigabytes, failing frequently,
one used for spare parts, now there are three.

Three little gigabytes, have too much to do

I've done something similer in the past with a 40GB drive. I managed to get 67GB out of it. Worked fine and all the space was usable. The only problem was bad sectors, after only 2 weeks I had 15% of the dirve unusable, and after a month I couldn't even accsess it. So while it dose work it will quickly devistate the life expectince of the drive.

On a side note a freand of mine tried this with his 20GB drive at around the same time, cranked it up to 32GB... Funny thing is it still fully works. Amazing isn't. Just don't try it at home :)
