hi i have a external drive 1.36T There was a power failure when the process was 01% completed. When I try to access to the drive it says: bitlocker drive encryption faild to recover from an abruptly terminated conversion. this coud be due to rither all conversion logs being corrupted or the media being write-protected.

Hi, You can use the Bitlocker Repair Tool try to repair the data. If you can't repair it, I suggest you to format the disk.
