    BitLocker Encryption on External Hard Drives


    Recently upgraded to Windows OS 8.1 Pro and cannot encrypt my HP external hard drive. Encryption pauses and states that disk has errors and please run chkdsk. Ran chkdsk and no errors found. Had no difficulty encrypting the C drive with the OS. Any suggestions?

    Go to the disk management and look at the external drive, under type make sure it says "Basic". Bitlocker can only encrypt devices which use that type.

    Check your policies:

    1. Windows key + R > type gpedit.msc

    2. From the left side, navigate to the following:

    Computer Configuration > Windows Components > Bitlocker Drive Encryption

    Check all the policies in this folder and it's subfolders - including any policies pertaining to enforcing "read only" permissions

    To all that have responded - thank you. I was able to encrypt the external drive by deleting all backup files from the drive. There was a lot of stuff on that drive and something must have been inhibiting BitLocker. After erasing the old backup files, it worked fine.
