Accidentally Formatted FileVault Encryption SSD

The only way to recover your data is from a backup made before you accidentally erased the SSD.

You have two things going against you here.

1. Erasing the Filevaulted drive destroyed the encryption key stored on the SSD. If you don't have the Filevault recovery key, then you have no way to unlock the encrypted volume
2. More importantly, once you "erase" an SSD all data on the SSD is completely destroyed due to how SSDs work internally (especially with TRIM support enabled).

Even an expensive professional data recovery service will be unable to recover your data now. Live and learn.

From now on have frequent & regular backups of any media that contains important & unique information (including external drives). The more important the data the more backups or copies you should have. Keep in mind that cloud syncing services are not a backup solution.

Hi Erman4764,

If I understand correctly, you accidentally formatted (erased) the internal drive on your MacBook Pro, and FileVault was enabled. Unfortunately, even with your password, the chances of recovering your data are small.

If your Mac was made in 2018 or later, the T2 Security Chip (or the Apple M1 chip) stores special keys that are required to unlock your data. These keys would have been permanently discarded when the erase occurred, making it basically impossible to recover the data. A successful recovery would have to attack the T2 Security Chip (or the Apple M1 chip) and attempt to recover the missing keys.

If your Mac was made in 2017 or later, shut it down immediately and take it to a professional data recovery service. Because all of the necessary keys were stored directly on the drive, there might be a chance that the needed keys could be recovered. Provide your login password to the recovery service when asked, as it is required in order to decrypt the decryption keys.
