Bitlocker Encryption Failed and Decryption Stuck RRS feed

  • Question

  • Hi Microsoft Admin

    Last Thursday I tried to use bitlocker on my drive E. C is my OS drive. Drive E is only for data and documents, which was why i was hoping I could lock it. When I ran bitlocker and start the encryption, it stopped on 25%. It didn't give me any option to cancel or else, it also frozen my laptop. So there was no any other way, I had to force restarted it. But it ruined everything ..

    I can not access my drive E, even using the recovery password. It's encrypted but not completely, corrupted.

    I've tried many things thene I found the way to decrypt Bitlocker drive using Bitlocker recovery tools, on scenarion 16. I recover my E to my External harddrive using this syntax :

    repair-bde E: I: -force -rp [recovery password]

    I am doing it now, it works .. but only til it reached 25% too, just like the encryption process before.

    Now it really really stop at 25%, been 1 hour like this. What should i do now ?

     

    I really need your help, because all of my project data and work documents are in that drive..

    thank you

  • Is it still stuck at 25% or it made progress?

    If it is still stuck at 25% then it has encounter a bad block on the disk.

    That was the reason the bde never completed successfully at first place.

    you need to search a get a tool from internet which can mark bad block and after this repair-bde might work for you and you can access the data.

  • Hi,

     

    Base my  knowledge, The BitLocker encryption and decryption processes can be interrupted by turning the computer off, and it will resume where it left off the next time Windows starts. This is true even if the power is suddenly unavailable.

    I recommend  that you may use the BitLocker Repair Tool to recover the driver,  for more information :

  • Hi i have a samsung 500gigs that i used on windows 7 ultimate which i partitioned to 150g and 350g, so i locked the 350g partition with bitlocker and yesterday i decided to remove bitlocker on that partition and there was a power failure while the decryption was on 2% after that i switched on the computer and it freeze  on the Microsoft windows screen but if i disconnect the drive windows will open just fine. So i tried to put it to connect it with a external usb and the first partition is there on my computer and the bitlocked partition doesn't appear at all i even tried to connect on a windows XP machine it opened and the bitlocked partition wants to format..

    Please  help coz i wanted to try the (repair-bde) command but i don't know how to specify the drive letter because  it doesn't appear on my computer only the ather partition wich was not locked appears
