Bitlocker Stuck at 84% in win 10 Pro. I am Unable to pause, turnoff or use my computer. RRS feed

  • Question

  • Hi, It has been a week since I lost access to my data partition. I have searched a lot to get solution but to no avail. I hope someone will have some idea how to fix this.

    I upgraded to win 10 pro and decided to use bitlocker on my data partition (D:). Bitlocker reached 84.1% in few hours and then it stop progressing. I waited for two days before I started worrying. At this point the computer is uselessly slow to the point it will take 5-10 minute for me to open anything. I found out that the cpu and memory is not used a lot but the hard disk is at 100% usage.

    I opened command com with elevated privilege  and tried to pause bitlocker but it did not work. I also tried to turn off bitlocker on that partition but that did not work either. These are some of the commands that I used in admi mode

    1.manage-bde -pause D:

    2.manage-bde -off D:

    The next thing that I tried is I shutdown the computer using the power off button(I took the risk).  When window start again, that partition was locked but now at-least I can use my pc. I can see the partition but I can not access it but if I unlock it using the password, bitlocker continue encrypting starting where it left an my pc becomes unusable again. Every thing becomes like toooo slow. 

    To recap this is where I am...

    1. Even though the encryption is not finished, I have the option to unlock the partition after I forcefully shutdown and turn on the PC by using the power button. I have  a working password and recovery Key. As soon as I enter the password to unlock the partition, it gets unlocked and encryption continues but it would not pass 84.1% and the system becomes dead slow again.

    2. I used password when I encrypt this partition. I have a working password and recovery file/key.

    3. I thought bitlocker faced some bad sectors with error even though it did not generate any message about bad sectors. I decided to run chkdsk from command prompt. I restarted the PC with my win7 pro recovery cd and tried to run chkdsk from command prompt "chkdsk D: /r" .It gave me some error message saying window can't perform chkdsk on raw partition or some thing like that.

    What I need to do......I need to stop bitlocker from trying to continue encryption so that either.....

    1. I could turn off bitlocker on that partition so that all my files are decrypted and never touch bitlocker again :-)  or

    2. I could pause bitlocker for a while and the partition stays unlocked and the PC becomes usable enough for me to copy all files on D: partition to external drive and then I could delete the partition or reformat it.

    As I have said in the beginning, I have tried to pause and turnoff  bitlocker from elevated command prompt before by using ......

    1.manage-bde -pause D:

    2.manage-bde -off D:

    to no avail. The command get executed but nothing changes. I know bitlocker is not paused because the PC will remain unusable. I also know bitlocker is not turned-off because I still can see the encryption process @84.1%.

    I have not tried bitlocker recovery app yet because I don't think It is relevant to my case. If anybody thinks that is the way to go, please let me know.

    Please let me know if you need further information.
