Initially I had 2TB Seagate Expansion Desk HDD, partitioned into 500GB, 13GB, 500GB, all three Bitlocker encrypted and 1 more 500GB unencrypted partition, the rest of the space was unallocated. Yesterday, by mistake, while I was creating Windows Recovery Disk chose the wrong drive letter and ended up whole partitions above deleted. Here's what I have in HDD now: 32GB Windows 8 Recovery partition and 1831GB unallocated space. After that I haven't made any changes to the drive. I was able to restore the data from the last unencrypted part by using Getdataback SW but with no luck in my Bitlocker encrypted partitions. I would appreciate any advice to restore the bitlockerencrypted partitions as I have the password to decrypt and retrieve my data back. Thank you, Super Users.
