• 0xC0000221 error windows didn't load a critical system driver is missing or corrupt.

  Hey, I got a letter on my laptop to install service pack 2 for windows vista and I did it with no complications until I reset my laptop and when it came back I received an error:

  Windows could not start. A recent hardware or software change might be the cause. To solve the problem:

  1. Insert your windows installation disc and restart your computer.
  2. choose your language settings, and then click "next".
  3. click on "repair your computer."

  If you do not have the disk, contact your system administrator or computer manufacturer for assistance.

  File: \Windows\System32\drivers\ecache.sys
  Status: 0xc0000221
  Info: Windows could not load a critical system driver is missing or corrupt.

  I followed these instructions several times and made repairs to start ending telling me that "Windows cannot repair this problem automatically" and "If you recently set a device to this computer, like a camera or portable music player, remove it and then restart your computer." I have nothing connected to the computer.

  I also tried to restore the system that is not no matter how far back that I try to restore to.

• Cannot use Bit Locker encryption because Bit Locker critical system files are missing or damaged.

  Original title: file corruption

  My laptop is around the age of 13 months. For the 6 months charges I couldn't play all the music in the music library of the media player. the error message would say my music files have been damaged or corrupted. I tried to delete the files, but could not. unexpetedly about 2 weeks ago the media player has started working properly, and even though I was confused, I was happy to be able to listen to my music. However, when I did my weekly back, a message appeared that said that some files could not be backed up. My computer has since fallen twice and had to repair itself and then when I tried my weekly backup only yesterday, the computer won't start backup. reads the error message: Bit Locker encryption cannot be used because the Bit Locker critical system files are missing or damaged.

  I find it strange that "file corruption" has been cited again but when I try recommended fixes, nothing changes, just as it was when I had problems with the music. Help, please

  If the system or Mode restore safe work not and you do not have a Microsoft Vista DVD, make a repair disc to do a Startup Repair:

  Download the ISO on the link provided and make a record of repair time it starts.

  Go to your Bios/Setup, or the Boot Menu at startup and change the Boot order to make the DVD/CD drive 1st in the boot order, then reboot with the disk in the drive.

  At the startup/power on you should see at the bottom of the screen either F2 or DELETE, go to Setup/Bios or F12 for the Boot Menu.

  When you have changed that, insert the Bootable disk you did in the drive and reboot.

• Audio loss. UAA Bus Driver reads Windows cannot load the driver for this hardware device. The driver may be corrupted or missing. (Code 39). All the patches?

  Audio loss.  Device Manager indicates Microsoft UAA Bus Driver as: "Windows cannot load the driver for this hardware device. The driver may be corrupted or missing. (Code 39) ».  Tried to update driver and restore without success.  Tried the program of "Fix - It", which has identified an error with the sound system, but said that he could not fix it.  Restored to an earlier date but still what system did not go.  Tried to uninstall and reinstall the driver.  Uninstall was successful but reinstall it read that the hdaubus file does not exist.  I'm a computer dunce.  Any help out there?

  Hi BarbaraWolfe,
   

  There are many causes of Code 39 errors:

  • A required device driver is missing.
  • A required binary file is corrupted.
  • There is a problem with the file I/O process.
  • A driver that refers to an entry point in another binary file cannot load.
  Re-install the driver by downloading it from the link given:
   
  Universal Audio Architecture (UAA) High Definition Audio class driver version 1. 0a available for Windows XP, Windows Server 2003, and Windows 2000

  Help, please! Windows cannot load the device driver for this hardware (HL-DT-ST DVDRAM GH40F SCSI CdRom Device) because the driver may be corrupted or missing. (Code 39)

  Hello

  Code 39 means that the driver is corrupted or missing.

  Please make all below even if you have done some before as it is often the set of operations which solves
  the question.

  Try this - Panel - Device Manager - CD/DVD - double-click on the device - driver tab - click
  Update the drivers (this will probably do nothing) - then RIGHT click the drive - UNINSTALL - REBOOT
  This will refresh the default driver stack. Even if the reader does not appear to continue below.
  
  Then, work your way through these - don't forget the drive might be bad, could be a loose cable or
  slight corrosion on the contacts (usually for a laptop) and other issues.

• Windows cannot load driver DVD - RW - Code 39

  Accidentally, I messed up my cd-rom drive. Just recently, I bought a toshiba as100-s40dt and when I tried to play a dvd, it says that the DVD cannot be read because the region is not supported by the drive of cd-rom. I realized I can do only 4 changes so I thought maybe I could just download a software that can help me play the DVD without change the region settings in my laptop. I downloaded a software named DVD UnlockerDriver64 and as I restarted my laptop, I can't find my dvd drive in Explorer as well.

  It all started with the code 52 so we are trying to update the driver, it changed to code 39.

  Windows cannot load the driver for this hardware device. The driver may be damaged or

  Sing (code 39).

  (Could not load the device driver)

  HS device driver could not be loaded.

  Error status is 0 x %x

  

  I checked my driver and it says that I still have the best driver installed in my system.

  Help, please.

  Hello

  BTW, you should check with the support of this DVD Unlocker program since it is the
  cause of your disorder.

  Don't forget to check with the support of Toshia because OEM, they are responsible for the good
  operating Windows and hardware.

  I hope this helps.
