1. Lock & Unlock Your Computer

Do you want to lock and unlock your computer with a physical device, like they do in the movies? Use the free PREDATOR application, which turns a USB flash drive into an access control device – a key for your computer. When you leave your PC, unplug the USB stick and your computer will be locked. When you return, plug it back in and your computer will be unlocked. It’s like using the Lock function in Windows, but you don’t have to type your password when you return.

When you unplug your USB flash drive, your open windows will minimize and your screen will go dark – plug it back in and your screen will turn back on.

ReadyBoost also requires a flash drive with at least 256 MB of free space.

    "Increase Performance With ReadyBoost" - but in my case, with a Class 6 SD flash card in the SD slot.
    USB 2 or 3 flash sticks allow RAID-0 in Linux operating systems. On most (all?) portable computers, this is probably the only way to bypass the slow cylinder-based hard disk drive(s). In my dual-HDD desktop-replacement notebook, I can also RAID-0 in Linux as well, but have not yet succeeded.

      Windows can use USB drives for striped volumes which are basically software RAID 0.

    • Chris Hoffman
      September 30, 2012 at 3:40 am

    I used a 16GB PNY flash drive like a hdd.
    I put Ubuntu on it, and when I rebooted, I choose the flash drive as the boot drive.
    I'm trying to learn Linux,
    and it runs *way* better on the flash drive than a 'live CD'.
    Unfortunately, I tried to wipe it and install another version,
    and now I can't get the drive to 'recover' to the point of being able to reinstall
    Any suggestions?

    • UbuntuGuy
      September 12, 2012 at 12:56 pm

      Plug it into a Windows pc and it will ask you to reformat it.

      • sl0j0n
        September 14, 2012 at 3:17 am

        Yeah, no, that didn't work, either, over and over and over,
        over and over and over, again.
        In fact, by the time I posted about here,
        I'd already tried like 8 or 10 different freeware programs to partition and format it.
        I went on to try about that many more.
        A *partial* list includes;
        Active@ Partition Manager Free Edition.exe,
        Aefdisk command-line-tool.exe,
        Aomei Partition Assisstant Home Edition.exe,
        EaseUS Partition Master Home Edition 9.1.1.exe,
        Eassos PartitionGuru Free.exe,
        Eassos Partition Recovery Free.exe,
        MiniAide Magic Partition Home Edition.exe,
        Paragon Partition Manager Demo.msi, [an old 'standby', it wouldn't run under win7],
        Partition Wizard Home Edition.exe,
        Partition Wizard Home Edition.iso,
        Wondershare Disk Manager Free full719.exe.
        I also tried the partition and format tools in a few Linux distros,
        Mint and Ubuntu spring to mind.
        Finally, I solved the problem,
        by downloading/burning and using the latest GParted version.
        IF you have a similar problem,
        do NOT hesitate to try GParted LiveCD
        Really, go ahead and dwnld now, and burn it to disk,
        so you'll have it—when you need it.

        Have a GREAT day, neighbors!

        • UbuntuGuy
          September 23, 2012 at 12:18 pm

          OOPS! Sorry, I abandoned this thread. Yes, Gparted would have been my second choice if the Windows trick failed. I use it regularly when installing operating systems.

          USB sticks and flash cards have limited lives, including complete breakdowns. Independent bench tests (url misplaced) have shown that flash sticks format.& cards give almost unpredictable bench results, regardless of brand or claimed speeds.
          In you case IMO you have experienced something that happens several times each year: flash breakdown.
          One manufacturer claims that only use 'quick reformat'; not full reformat. I only buy the cheapest available on eBay, so have found that complete or fast format makes no difference.
          To my biggest surprise, my flashsticks & cards survive the front-loading home washing machine (warm water).
          Since I multi-boot (2xWindows, + 6 Linux operating systems) on my main PC, plus maintain other machines, I very heavily use many flash sticks & cards; plus smartphones, cameras, tablets, netbooks, etc.

          October 28, 2012 at 3:37 pm

          This article & the comments that follow miss out THE MAIN PURPOSE of a flash stick: DEBUGGING.
          On the many 'computers' that I maintain, it could be hardware, software, networking, malware, incompatiblities, etc ... so I MUST use a flash stick to debug.
          Linux has many specialized debugging-specialized operating systems. However, I use Xubuntu (lightweight, speedy) 32 bit, loaded with antivirus & all sort of hardware drivers, to debug anything & everything with a USB port.
          USB ports can also take WiFi, bluetooth, screen, audio and keyboard add-ons. These, as needed with my Xubuntu USB stick, can debug almost everything.
          All operating systems and the popular multi-national apps also have much international junk on them. This I remove, plus other operating system rubbish: unreadable files & folders, pagefiles, hibernation, etc.
          Often the boot drive becomes so overloaded that the computer refuses to operate.
          To those who do not know Linux, the 'buntu distributions can easily read-write all NTFS and AFAIK Apple file systems. Personally my PCs are in the W7-NTFS-compressed-encrypted file formats, & the 'buntu brand of Linux can easily co-exist with this.

      I'm assuming it's an Android - You could install Ubuntu Live on it. But it might not be useable as storage afterward on the phone itself. When you plug in your phone into your computer it becomes a regular USB flash drive. Once Ubuntu Live (or your Live distro of choice) is installed just boot your pc off of your tethered phone.

      I was going to try it on my Android one of these days.

    Nice article. Tried Predator back in 2010, but having to keep it plugged in, while using the PC was boring for me...
    My USB flash drive houses the Puppy Linux OS, together with TRK.
    I also keep lots of tools and softwares to troubleshoot PCs.
    My last thing would be flash drive with a physical lock for write access.
    But for now am moving from flash drive to flash cards (in a card reader) that gives me physical lock for write access. This way I can protect my data from being overwritten by nasty malwares / viruses.

    I really thought that you can use your flash drive as a key, something like to open your pc, now I have a proof to prove that theory of mine thx for the info!

    Thanks for the info...going to try out one suggestion on an older laptop of mine. I will report back here how it helped with the speed. In a week I am converting it over to we go.

    What about some unknown uses for us Mac users? Can you instal MAMP on a flash drive? That would be handy.

      You probably could somehow, but it doesn't seem like anyone's done the work of making it nice and easy.

      (Sorry, I'm not a Mac user, myself.)

    One more thing, you can also install Operating System on USB drive (at least linux) and use it on any computer with your personalized settings

    What if you lost your USB drive after your PC is locked?

      According the Predator's website one can still unlock his or her computer.

      FAQ: How to unlock a session using the password ?

      Follow these instructions:

      Click anywhere on the screen with the left mouse button, then press 3 times the Enter key, which will bring up a dialog for entering the password, and a countdown.

      You have 3 tries and 20 seconds to type the password. After this time, the alarm will be triggered.

      If you have not managed to enter the correct password after 3 attempts, the session will be locked for 5 minutes and you won't be allowed to retry during this delay.

      Note: entering a password, whatever its outcome, is recorded in the log. By reading it, you'll know if someone tried to unlock your computer.

    I carry Ubuntu Live on a 8GB USB drive which is on my keychain. I can boot just about any late model computer and boot into a full Ubuntu OS with all of my settings/programs/documents/etc already there. Who needs to carry around a laptop when I have one on my keychain. Good tool to rescuce data from a virus infected Windows pc.

      I love having my Ubuntu live image anywhere I go. It certainly helps too when people's computers have gone wonky.

    Using a USB like a key to lock/unlock sounds really cool. I think it'd quickly lose the sense of novelty, though. I'd give it a shot if I had a spare flash drive.

      Chris, your info on readyboost is a little under-researched.

      I run 10,000RPM disks in a RAID 0 configuration. My read/write speeds can easily pass 200/120gb/s. To some, this would be considered ridiculous.
      Readyboost is still VERY useful even with my less common setup.

      Spinning disk drives are still very useful for reading data accessed in sequence.
      Solid state drives excel in just about all other ways though.

      You should use BOTH whenever possible. OS on SSD, cache (pagefile/swap) on the HDD. Why? Because it extends the life of your SSD, and improves performance, as long as you use readyboost.

      Yes, you do lessen the flash drive's mean-time-to-fail, but a 4gb flash drive is a whole lot cheaper than a SSD. One which may house your OS and important data.

      If you're still reading, good, you're going to learn something.
      Readyboost only swaps your small, randomly placed cached files. Which solid state (flash) memory is much faster at reading than a disk drive.
      Your large sequenced data is left for the disk to handle, which it handles well.

        Well, that doesn't fit with the benchmarks I've seen. (for example: ) If you have a lot of RAM, Windows just stores ReadyBoost data in your RAM instead of on a Flash drive, which is even faster.

    • Chris Hoffman

      It probably would lose the sense of novelty, but it's pretty cool at first glance. Just like in the movies!
