I've had windows 7 encrypted files (my backups) on regular IDE disk, on partition of course.
When i was formatting my main hard drive, i've assidently deleted whole partition with that encrypted data. (deleted wrong partition by mistake)
Is there any way i can recover whole partition or at least some. I have my decryption key saved.
You can try this freeware to recover your data: http://www.squidoo.com/tested-data-recovery-freeware-re...
Or you prefer to use a specific deleted partition recovery tool: http://www.vimxsoft.com/partition-recovery/
Note for you:
1. Stop using this disk right now to avoid overwriting the original data. Any new data on it may decrease the chances of successful data recovery.
2. Save your recovered files on a different storage device in case of recovery failure.
3. Always back up you data in the future.
4. Create a new partition after the recovery process.
It's very unlikely that you will be able to recover your encrypted data. Recovery tools will not be able to see any files for recovery, only random noise due to the encryption. BitLocker (you did say you were using native encryption) doesn't simply encrypt the files but encrypts the entire volume in 16KB chunks. There is no recognizable filesystem left behind on an encrypted, locked volume. Now, if all that was done was to delete the partition then it <may> be possible to restore the partition table to its former self using recovery tools. However, if you formatted the partition as you indicated earlier then you can kiss the data goodbye.
