BitLocker Decrypting Still in Progress RRS feed

  • Question

  • So a while back I encrypted my external hard drive with BitLocker. Recently I have been getting problems with Bitlocker so I've decided to remove it and start decrypting. Currently the decrypting has stop for over 24 hours. I have tried restarting my computer, unplugging it and then restarting and many other failed solutions. After I plugging it now still decrypting the external hard drive (87.3% Completed). Due to the frozen decrypting I can't access my files on the external hard drive. HELP ME!

    Thanks In Advance!

  • Hi,

    If you have a backup of the external  hard drive, try to verify the backup, format the drive and restore from backup.

    If you haven’t, we could try to use repair-bde command to get the data out of the drive.

    Attach external portable hard disk at least equal to your original drive.

    Open elevated command prompt and then run:

    repair-bde E: G: -f -rp  567468-315348-618893-269918-444312-064559-109615-687632 -lf c:\log.txt

    where E is the original drive

    G is the new hard disk where we will get the data

    -rp is recovery password

    -lf is log file location

     

    After repair-bde is completed 100%, you need to run chkdsk on G drive before you use it.

    >chkdsk g: /r

    However, not every drive could use the command to transfer data completely, corrupt physical hard disk would not allow you to transfer data to a new hard drive.

    Best regards,

    Joy.

  • Hi Ty,

    We could use another external hard drive. It is not relate to old or new external drive, it is related to if it has enough space to received data.

    If you have any other concerns, please contact me at any time.

    Bests,

    Joy.

  • Hi Ty,

    I compared your capture with my provided command, I found you less one punctuation -. I have bold them.

    Try to run them again to check the issue.

    repair-bde E: G: -f -rp  567468-315348-618893-269918-444312-064559-109615-687632 -lf c:\log.txt

    Bests,

    Joy.

  • Hi,

    I suspect there would be a space missing or redundant, or have a wrong punctuation format. So I copy an example from Microsoft official website, and paste it here.

    repair-bde C: D: -rk F:\RecoveryKey.bek –lf Z:\log.txt

    We should better replace the file location, change the drive letter and to check the syntax again.(please keep the other words remained instead of typing them) rk means recovery key. Change the location with yours.
