How to recover data from a unallocated (deleted), BitLocker enabled partition?

    Question

  • Hello,

    when i used my win 10 my (media) Hard disk suddenly unallocated with 2 partition one it. one of the partition was encrypted with bitlocker

    Now I used window 7 ultimate and to try to recover my data I follow steps according to the great guide :
    http://www.normanbauer.com/2013/07/25/how-to-recover-data-from-a-deleted-bitlocker-enabled-partition/

    Now the problem was on the step to create recover.img :
    when i type "repair-bde F: E:\recover.img -rp 517253-653510-042988-665027-063393-559515-700700-268211"
    I get ERROR: cannot use 517253-653510-042988-665027-063393-559515-700700-268211 (the recovery key) to unlock the input volume, please try different recovery password or recovery key

    I am sure that it is the right recovery key. 

    I also have identifier and password for the bitlocker partition

    PLEASE ADVICE my Data is very important   !

    In addition, I agree with you, sometimes bitlocker will have some odd problems.

  • The only solution is never to use Bitlocker again in windows !

    It make no sense that there is no solution although that i have the recovery key and password !
