Recover partition or data from an encrypted disk

Hello all,

When i reinstall my Windows 10, I delete the partition on my second hard drive by error.
That second hard drive was encrypted with BitLocker.
Is there a software to retrieve the data that was on that drive.
I have the decryption key.

It's the same old story:

1 be careful. Rather clone your drive sector by sector using tools that can do it and work on the clone than trying to work with the original data
2 restoring the partition structure is possible, for example using c. grenier's "test disk"
3 when the structure is restored, you will be able to apply the recovery key/password to unlock the drive

(4) why no backup if the data is important?

To recover in-place, at a minimum it would be necessary to rebuild the partition table to match exactly what it was before.  Even then I'm not sure the information could be recovered.  As the partition was encrypted, there is nothing there now that a disk recovery tool such as RECUVA or R-Studio can latch onto.

If the information on that partition is worth retrieving, I'd send it out to a professional service such as Kroll Ontrack.  I'd certainly call their toll-free number and get the free evaluation before doing anything at all.

I stand with McKnife 100% on the backup issue.  If encrypted information is worth recovering, it is worth backing it up, unencrypted, before a disaster occurs.

I am afraid you cannot. You can use Active Disk Undelete Partition tool to restore the partition backup with a hope that Active Disk is aware of the encryption type used. Or use Undelete Partition Wizard from Paragon Hard Disk Manager if you have one at hand. It knows the BitLocker at least.
Introduction to R

R is considered the predominant language for data scientist and statisticians. Learn how to use R for your own data science projects.

The encryption type does not matter at all and tools don't need to be aware of it. If the partitioning is restored, all is good.

If the whole drive was encrypted and not just a partition then recovery tools will fail  to recover the partition table.
That is wrong. "The whole drive" does not exist, it is still a number of partitions that can be viewed without knowing encryption keys.

I tried everything you suggest and noting works so far.
I'm still looking for a solution.

The data on that drive was not valuables.
I was more appeal by the challenge to retrieve the data then the real value of the data.

Thanks for your input so far.
So you tried test disk? What did it reveal?

Hello McKnife,

Thanks for you help.

When the analyse/scan is completed, I just have the message "No partition found or selected for recovery"

I attached a file with the image I took.

Thanks again
Hmm, doesn't look good. No further idea but to try different tools. EaseUs partition recovery worked good, once.

Hello all,

Nothing seems to works.  So my conclusion: I need to reformat the drive and get the data back from a backup.
