BitLocker without TPM refuses to recognize the USB key at startup.

I have a Windows 7 PC, I'd need to BitLocker, but it fails to recognize the USB key at startup. I've resorted to skip verification and now enter the recovery key every time you start (this PC has a lot of data on what should be confidential), but it's not ideal.

What is curious to me, is that the computer will start perfectly fine from a USB key, or produce a message of type "non system disk or disk error", if the USB key in question is not bootable. So it is not a matter of lack compatibility USB BIOS. When Bitlocker should read, yet there is no actifvity on the USB key. It seems to just try to read the empty floppy drive then give up.

The PC is an all-in-one RM with an Intel D915GX motherboard.

I tried two different USB, 64 megabytes cheapo player drives I usually use as a Bitlocker key and a 2 GB Cruzer Blade. I mucked with some of the BIOS settings but not in a particularly organized way. And I checked the key file is saved on the disk. Everything I did, Bitlocker will not always see the USB.

Any suggestions?

  • Cannot access BIOS when OS disk encrypted w / Bitlocker, starting on the USB key is not unlock disc

    Hello

    I enabled Bitlocker on my Acer Aspire 5315. The system partition is encrypted and the data partition. My motherboard doesn't have a TPM chip, so I opted for the unlock with a USB key.

    When I start the PC or wake them from their hibernation, the splashboot (with the logo of Acer) BIOS screen does not display the information below on how to access the BIOS (press F2) or the boot menu (F12). And therefore I can't access those as I used to.

    BitLocker does not account for the USB key, then asks for the password to unlock the HARD drive. Then Windows starts very well.

    However, restart (by a Windows or after you have entered the wrong password Bitlocker too many times), the BIOS splash screen is normal (with how access BIOS and boot menu), I can access BIOS by pressing F2 AND succesfully Bitlocker unlocks the HARD drive with the USB flash drive without having to ask for the password.

    So, my question is how Bitlocker unlock the HARD disk automatically via the USB when the PC starts?

    Thank you for reading.

    Note: I posted this question on http://social.technet.microsoft.com/Forums/en-US/w8itprosecurity/threads they suggested that I ask the Acer support.

    Thank you also get answers in the TechNet forums.  I'm sorry that you were unable to get a more complete answer it.

    We suggest that you uninstall BitLocker and decrypt the drive to determine if this restores your ability to access the BIOS.

  • DreamColor LP2480zx does not recognize the USB for calibration

    Hello

    I have a DreamColor LP2480zx, which does not recognize the USB connection to the computer during calibration.  I have my eye HP connected through this monitor, so I know the connection and the cable is good and mouse, keyboard.  My setup is like this:

    Reference Dell 690 running 64 bit + Windows XP

    DreamColor LP2480zx

    Apple Cinema Display 23 "

    I bought the DreamColor used, and in all other respects, it seems to work very well.  The original owner didn't have it calibrated within a certain time, but said that having had no problem with the previous calibration.  I installed the last APS (version 2.0) and updated to the latest firmware.  These updates produces no change in recognition USB problem.

    The interesting thing is, I was able to calibrate the Apple Cinema Display, using the same configuration of connection (mouse, keyboard, and HP eye connected to the computer via the LP2480zx) APS was able to see the USB connection and this very well calibrated monitor.

    I had trouble with this problem for a few days.  I've looked around quite a bit online and found a few others who have this same problem, but I did not yet find someone who can point out a solution.  If anyone has had this same problem, or has heard of results that correct it, please let me know, because it's very frustrating.

    Thanks for any help

    Clay

    An update to my previous post, I realized a work around for this problem.

    Apparently, this problem has to do with the Dreamcolor screen and/or software APS do not like working with 64 bit systems.  I'm not saying that it is always the case, but I saw the other posts on this problem on 64-bit systems, and I spoke with two other people personally who told me that they also had the same problem, try to calibrate its Dreamcolor monitor when it was attached to a 64-bit system.  HP does not seem to be concerned about this problem, because they do not even recognize its existence, but since I'm far from being the first to report this problem, he's obviously not a one-time problem.

    My solution was this: I had connect the monitor to a regular running XP 32 bit system.  After I did, I could re - calibrate the monitor without the problem of USB connection.  This isn't a very good solution because not everyone has access to several machines, running different operating systems.  But it's a work around, and it worked for me.

    Hope this helps other people who have this same problem with their Dreamcolor monitors hooked to their 64-bit systems.

    Clay

    PS- I posted this as resolved, only because I was able to calibrate my monitor.  It's not really solved the problem, but it gets the monitor working again.  Maybe HP will address this problem in the future, but I'm not holding my breath.

  • Satellite A200-1AE does not recognize the USB 2.0 flash drive

    I have a problem because my satellite A200-1AE with Microsoft Vista does not recognize the USB 2.0 flash drive. He asks me a program/software!
    The same USB works without problem on other computers with vista!

    Someone knows what to do?

    Hello

    First of all, you must disconnect all USB devices and must remove the USB ports and controllers in the Device Manager.
    After this procedure, you must restart the laptop. After a new restart the Vista operating system should recognize the USB ports and should reinstall USB drivers again.

    Then you must update the Vista to the State! All fixes and patches must be installed. Please note that you will have to visit the MS Update site for all patches

    Notes; MS has released a beta of Vista SP1. I installed it on my laptop and it has solved several problems.

    Best regards

  • Windows does not recognize the USB flash drive

    Hello
    My USB does not work when I plug. It seems that Windows recognizes the device because it is found in the Solution Explorer window, but if I want to create a folder or a file on the USB key I have the following message:
    "Cannot find this article.
    It is no longer in < %3="" null :="" optext=""> . Check the location of the components and try again. " < br=""> also the files that are copied to the USB flash drive are not visible in Explorer and it looks like the drive is empty.

    I want to emphasize that the same (Kingston) USB flash drive works perfectly under Windows XP operating system on another computer so it may not be a problem with the device. The same problem also appears when you use a different USB (another manufacturer).

    Thank you!

    Hey, 101 a.

    , I just posted a fix I found for my USB flash/go to work again.  It was a very simple solution, too.

    I unplugged all USB devices first, then tried my USB jump drive again.  IT WORKED! I've narrowed the problem to the new printer that I use.  It's a Mono Dell Laser MFP 1125.  Whenever it is plugged into a USB port, my USB doesn't work.  All other devices work, but not the USB is the printer is connected

    I don't know what done to block the flash/USB key, but unplug printer allows the jump command to work again.  I will contact Dell on what did the printer driver to block the flash player.  Just an info on the fix I found.

  • Questions of BitLocker read only not my USB key at startup to test before encryption Win 7 ultimate

    My computer hp laptop has TPM and bios is up to date as far as I know. To be honest, I'm sure that's not bios issue or a USB problem.

    I scoured internet and found the same unresolved issues with no will. For some reason any bitlocker app WILL create a key USB and MPT will be turned on. However, and fortunately, when I leave a test before the actual encryption process, Bitlocker will give me an error code saying that the key could not be detected on the USB after the reboot.

    If anyone of you has a real address and went through this answer please. If you don't know what you are talking about please pass. I just need to run more.

    Thank you and much obliged to those who can solve this problem.

    After deducting - more to guess and pray - I tried two things. Firstly I have updated the bios on the Hp page. To be honest I don't think it was the cure.

    What I think don't have it really that my USB drive has not been formatted to NTFS. Effing Windows says nothing of this during the test before encryption. I strongly advice that this is done before you encrypt, then check the box before you start! USB is in FAT32 or whatever and once I transferred all the files on hard drive and then deleted everything I formatted, it new and transferred all back. I then tried again to encrypt and Windows Ultimate edition finally recognize the encryption key on the USB port and have begun to encrypt - which takes a lot of time on my 500g SSD.

    before to make this mark of course, you delete the previous Bitlocker and TPM key facts of the attempts failed, so you don't get confused. The computer that is known, but unless you wrote, or have a photographic memory, you might get confused as well.* *.

    In addition, I don't know if it would have made a difference, but I reset the Bios to factory settings before the the reattempt and I deleted the password BIOS TPM preceding on the USB as well, so I'm not confused. My system is pretty bone bare, so nothing has been maleffected. Restart the BIOS will ask you if you want to make these changes or not.

    I hope this helps. I know that whenever I'm searching for answers here they never really. Most of the answers just to get out of the people *. See you soon!
