How to recover data after Bitlocker decryption failed?

2018-5-11, Posted by Jerry to BitLocker Data Recovery

I was trying to decrypt a Bitlocker protected external hard disk overnight and it seems to be stuck at 45%. I waited for another couple of hours, but the progress was still unchanged, then I paused and then resumed the decryption, the problem persists, so I realized that the decryption had failed. There's over 100 GB worth of some pretty important files on this drive, so I'm eager to get those files back. Can someone tell me how to recover data after Bitlocker decryption failed? I'd be willing to pay a reasonable amount for a software solution.

If you’re experiencing this, we recommend that you pause the decryption and restart the computer and try again, or try decrypting on another computer. If the the problem still persists, the file system has been corrupted or BitLocker metadata has been corrupted after the decryption failed. Because Windows is no longer able to unlock this partition, we have to use data recovery software to recover data from the decryption failed Bitlocker drive. The common data recovery software cannot recover data from BitLocker encrypted partitions, so we recommend that you use professional BitLocker data recovery software Hasleo Data Recovery to recover data after Bitlocker decryption failed.

Please note that:
1. Bitlocker metadata must be intact: Bitlocker metadata was used to store the password and 48-digits recovery key when encrypting the drive with Bitlocker. In some situations, Bitlocker metadata has been corrupted so that lost data cannot be recovered even if you have correct password or recovery key.
2. Have correct password or 48-digits recovery key: The password or 48-digits recovery key is used to decrypt data from Bitlocker encrypted drive after the password or 48-digits recovery key you enter matches the password or 48-digits recovery key stored in Bitlocker metadata.
3. Don't save the recovered files to the partition where your lost files originally located. This prevents your data from geting overwriten.
