Formatted and re-partitioned the USB key without realising it was the bitlocker key, still have the key file that was on it on a seperate computer. PC restarted and now boots with nothing on screen for about 60 seconds then turns off. Fast boot enabled in bios so i cannot access BIOS as it tries to boot straight to windows. what should I do?

Data Recovery in Bitlocker Encrypted Drive

Today my home laptop system asked for bit locker password after booting up (before login). Bit locker encryption was not enabled by me. However, to make the computer usable, C drive was formatted since there was no critical data in C Drive. However D Drive is still encrypted.



Kindly confirm

1. Can Bitlocker Encryption be enabled without intervention of the user?
   
2. Where to find the bitlocker encryption key?
   
3. How to recover the Data in Encrypted D Drive?
   

 

Bitlocker encrypted corrupt usb drive.

Hi Patriq,

Thank you for posting your question in the Microsoft Community Forums.

Appreciate your efforts to work on this issue.

I can understand the situation must be difficult for you when the Bitlocker encrypted USB drive doesn't work as it should.

Please answer these questions to get more clarity on this issue:

1. Does the USB drive work on a different PC?
   
2. What is the error code or message you get while trying to access the USB drive?
   
3. Do you have the Bitlocker recovery key for the external hard disk?.
   

However, let us follow these methods to ensure that the USB drive gets recognized on the PC. Once this is done then you can use the encryption key to decrypt the drive after which you can access the files on the drive. As there is data on the drive
which is not backed up, suggest you not to format the drive as this action will result in data loss.

Method 1: Plug in the USB drive into another PC to check if the drive gets recognized and if yes, then you can try to access the files in the drive.

Method 2: As you are able to see the drive when you boot under UEFI, suggest you to run check disk to fix any bad sectors on the external hard drive and check if that helps.

Check Disk or Chkdsk.exe is a built-in Windows utility used to check for errors in the disk media and in the file system. The Check Disk utility or ChkDsk.exe checks file system errors, bad sectors, lost clusters, and so on.

Note: While performing check disk on the hard drive if any bad sectors are found on the hard drive when chkdsk tries to repair that sector if any data available on that might be lost.

1. Open Command Prompt in admin mode. Click Start, type ‘Command Prompt’ and you’ll see “Command Prompt” listed as the main result. Right-click that result and choose “Run as administrator”.
   
2. Once CMD window is open, type ‘chkdsk (Your problem drive letter without parentheses): /x. This forces the volume to dismount. Also invalidates all open file handles.
   

Once this is done, restart the computer and see if that makes any difference.

Let us know how it goes.
