USB FlashDrives The New PC? 305

Posted by Zonk from the for-limited-amounts-of-functionality dept.
olddotter writes "Yahoo has an article about how large capacity USB drives might be redefining the concept of the personal computer. The article is windows specific, but think knopix on a flash drive." From the article: "When you check into an average hotel room and find -- alongside the alarm clock, hair dryer and DVD player that once were bring-your-own items but now are as standard as the furniture -- a cheap PC for guests to plug into, as our truly personal computing environment travels with us."

      I wouldn't trust a hotel (or net-cafe) computer with a USB stick with my private keys, certificates, or banking password. Even if you boot off your USB stick, how do you know it's not booting under Xen? I think it's more likely that the hotel computer has malware already. chambermaids are not sysadmins.

        This is referring to a computer with NO operating system at all. You have to provide everything, it's completely diskless, just a usb port. If they did anything, it would have to be at the proxy or some kinda tftp boot.

        Having a whole operating system on a flash drive isn't that unusual. I have been using Knoppix for years, like a million other people. The flashdrive would just be faster and smaller, and you could write to it and save some files if you chose to.

              You chose a really bad example up there ;-). At least in Europe fraud using manipulated or even completely bogus ATMs is not too infrequent according to police reports. Apparently there are a lot of mostly Eastern European gangs that either "enhance" real ATM systems with add-ons for the card reader and the keyboard that, while often not discernible on even closer inspection to the non-expert, can log the users PIN codes and grab the transmitted card data. Sometimes they even use complete real-looking fake-ATMs that trick you into entering your PIN and swallowing your ATM card afterwards. Until you have contacted the bank to get your card back from the presumed read ATM they are already spending your money using your real card and the PIN you gave them.

        Forget the sheets - think about the fact you're reusing the blankets from the previous parties (and the previous parties' leftovers).

        Speaking of the drives, Best Buy just finished having a sale of Memorex 2G sticks (retail $199) for $159 at the cash register, then another $30 for the rebate. Granted, you're looking at $10+ in taxes at each level, but it's still a heck of a discount. Not much more than some of the stores' retail prices for 1G, although I don't think anyone is going to pay the upper end of a 1G price scale. Those things were nearly impossible to find using the StoreFinder Inventory. I didn't want to order one and was going to my doctor's office in Chicago a couple of days after they sold out here in Indy, so I placed a pickup order there.

        Then, I happened to be picking up some laptops for our DARPA team from a repair shop, and when I went back to my car, there was a Best Buy sack (this was on the far side of the BB parking lot) which was on the passenger side of my car, so I opened it up. There was a 2G stick in it. Unopened. So I figured I'd do the nice nerd thing and track down the new owner. If they paid via credit card or cheque, it shouldn't have been a problem to track them down. Unfortunately, they paid in ca$h???? So I sat there for another hour, sitting & reading, sans A/C as it was fixed, then stopped working and I hadn't had time to take it back to be re-repaired. I don't tolerate heat very well, but I felt it was the decent thing to do. After an hour, I wasn't sure what to do, so I ended up putting it onto my lanyard, feeling badly for not having another way to find the owner.

        BTW, it's said you can't (or shouldn't) format NTFS, but both of mine seem to be working fine. I had the handle (which holds it on the lanyard) break off and had to finagle a fix, but also contacted Memorex. They told me to file it as a warranty issue to get a replacement cap. (???)

        One of my friends, who has a 512M stick, asked me what I was going to do with 4G of stick memory and I asked him what he did with 512M. He said he rarely comes close to capacity. I thought about marking one of them with tiny lettering: ICE (In Case of Emergency), sort of like the fad with cell phones, but a text file with the important info, in addition to the usual phone numbers (a list, and who they are - more options than a cell phone) as I usually have them around my neck; e.g. I'm allergic to morphine; my pain receptors have been exposed weekly exclusively to methadone for nearly ten years, so other pain meds may not work correctly; what other meds I'm taking; why all of this is so; etc.

    • With a a proper and flash specific file system the write limit problem is almost non-existant. Wear leveling can allow the memory to last for years. One of the reasons for the semi-crappy performance/dependibility of these flash drives is because they use FAT over a flash translation layer, which uses more writes than nessesary and doesnt include wear leveling. A real flash filing system such as YAFFS [aleph1.co.uk] is far more robust. The only problem is it requires support in the OS, which isn't included by default

      There are "spare" cells in flash drives just the same as there are "spare" blocks on hard drives. There are usually two controller chips in a USB drive (plus the flash chips) - they include the memory controller and a usb (or firewire if you happen to have one) bridge. The memory controller manages the memory and remaps cells that go bad, transparent to the usb/fw bridge. Anyone with a flash drive probably has some bad cells in it, just like hard drives 10 years ago that came with a label printed on the top listing all the bad blocks the new drive shipped with.

      Parent talks about "wear balancing" - interesting concept though I have not heard of it used on flash drives before... would be a nice idea but not too fun to implement.

      I use my flash drive several times a day at least, it's a 4gb SanDisk Cruzer Mini. Perfect for hauling around all the maintenance, repair, and update software that I use daily. I don't know why people buy those giant drives that don't fit well in a pocket and block adjacent USB ports. SanDisk also has a lifetime guarantee on their drives, so if mine ever does use up all its spares, I'll just trade it for a new one. Lacks a write protect switch though, which would kinda be nice.

      Also a less known factoid about USB drives... the fast ones - USB 2.0 "High Speed" (not to be confused with the "Full Speed" snails) only work in powered USB hubs. Can't plug them into the keyboard ports. I wish they'd fix that. I'm tired of having to crawl behind a computer to jack into one of the powered ports. Thankfully most manufacturers are placing a powered usb port on the front of their machines nowadays. (sometimes two)

      Would be nice too if Apple would fix OS X so it didn't reset all the #@*& USB buses 1.5 seconds into boot, so we could boot X off our flash drives.

    There's nothing magical about USB, or even a local disk.

    The key issue isn't that the data is on a USB disk, but that it is easy enough for you to carry around all your data (including OS and apps). E.g. compact flash would suffice. Or serial flash.

    Furthermore, just having secure access to the data (perhaps over the internet) would suffice. Imagine a system where to boot up, the PC fetches your data off the web. Perhaps you use a kind of use-once key to access some of the data, with which the PC computes.

    The thing I've not been satisfied with yet is the idea that the PC itself would engage in a man-in-the-middle attack. E.g. it stores a copy of whatever data you've accessed (off your USB, compact flash or network storage) -- and the bad guy gets that stuff later. There's no defense against this attack, because the PC is doing the processing.

    E.g. imagine a compromised PC running something like bochs. It emulates a real PC, but gives away your secrets.

    This sounds like a security/privacy nightmare. What stops the host PC from copying the drive or infecting it with malware from the prior user. Even if the USB drive uses an encrypted filesystem, once you type your password into the PC to access any file on the user data partition, you have no guarantee that it won't access every file on the drive. I can also see this giving corporate security managers the screaming heebie jeebies over the thought of returning road-warrior executives bringing infected USB drives inside the the corporate firewall (yes, you can scan for malware but you're still susceptible to zero-day attacks and delays in AV updates).

    Perhaps this would work if the client machine were truly memory-less (no HD, no NVRAM, no flash ROM, etc.). Then the machine could be a secure blank slate for whatever the USB user needed to do. Given the prevalence of flashable firmware on everything (and the need for persistent machine configuration data), I doubt this is very feasible.

    • Definitly the ideal would be to run the whole OS off the flash drive and have no storage or OS on the computer itself. Of course, this would currently only work with Linux (limited by Linux hardware support) and Macs. And Macs already have a good head start by being able to boot off of USB. And they don't generally have problems booting the same OS on different hardware. There are many modern PCs that cannot boot from a USB memory stick. And even if you could, we all know how picky Windows XP is about its h

You don't own the machine, you didn't install the hardware or pull the memory. It's sitting at that bios screen when you boot it... who's to say that's not a program that's running? Is there

    It worked pretty well. Whenever I came to a new mac, I would turn it off, plug in the iPod, and boot while holding down the "T" key to target the new drive. Unfortunately, the iPod's hard disk is not the speediest thing in the world. Moreover, I doubt toshiba driv

  • The article makes reference to this new "U3 technology" [u3.com] that enables a flash drive to run programs. Exactly what is the point of this? Does anybody know. As far as I know, any program should be able to run off any flash drive as long as it doesn't do something like store all its settings on the host computer's registry or something. Isn't that how stuff like Portable Firefox, Thunderbird, etc. work? So why exactly is this concept so hard to do that one needs a special software SDK and specially designe

      USB Flash Drives don't mount like say, a CD would, meaning you can't autorun anything. I believe that's what this U3 Technology does, it more or less adds autorun capabilities to the drive. I learned this tidbit about Flash Drives when my roommate and I tried to build a USB Game Controller, with a drive with some games on it. The idea was: plug it in and go. Unfortunately, we had the wrong kind of USB drive.
      • Wow..that's weird. I never thought that was a problem, because I have an autorun.inf on my flash drive that dictates the icon for it and adds an extra menu item. However, I just tried adding an autorunning program and you're right, Windows just came up with the autoplay menu because it found some pictures on the drive. Thanks for the explanation.

Keyboard/mouse/display terminals would be everywhere, and we would just carry the cards around and plug them in wherever. PDA type terminals would be available for portable use.

That way it doesn't matter what the host machine *is*, as qemu provides a complete virtual machine with all the required virtual drivers for basic use.

    This is, for all intents and purposes, what NeXT tried to do in the late 80s. The optical drive they used was ruinously expensive. The software was limited. Now, twenty years later, theidea is coming into its own. Devices like the USB key, the microdrive, and the Palm LifeDrive are actually spacious enough to make all of this work. Twenty years ago Jobs said you should be able to walk up to any personal computer and make it your own. Ten years ago Ellison said that you could access anything from anywhere. In five to ten years these visionary things may just really happen. Funny how the world works, isn't it...

    Why wouldn't there just be a monitor and keyboard?

    The article assumes that the processor/memory etc are bulky by definition. Movement towards miniturization and disposable computing mean that having an entire system may become nearly as cheap and small as the stick of memory you are booting off of.

    The only way to be truly secure is to have full control over the system you are using, so bringing your own entire machine will be a necesity for the crowd for whom inovations in hotels are usually designed for: business people.

    Also a USB key with an OS compiled for an alternative archetecture would be useless in a hotel box.

    The only two things which a handheld device cannot offer are a full sized display and interface. Why not just make everyone's handheld device interface with a monitor/keyboard/mouse console? Leave architecture compatibility issues to the user. Leave security to the user. Just provide a pleasant work environment.

    Ideas like this one are always based on one assumption: that everybody will be totally happy with the same keyboard layout. While it might be true US-wide for US-only customers, it's not true in Europe. All the European languages require keyboard layouts more or less different than the typical English QWERTY - such as the German QWERTZ or French AZERTY, not to mention all those weird accented characters that the Swedisch chef need to correctly spell his "bork! bork! bork!". Don't get me started with Slavic languages, especially those of Cyryllic alphabet... No European hotel would seriously consider offering this service as it would lock-out foreign visitors. Personally, I'm just totally happy traveling with my powerbook as my personal computer, all I want from the hotel is to have Airport and access to their printers.
