Recovery and decryption are separate problems
Laboratory work may repair a drive, stabilise it or image readable sectors. If the volume was encrypted, that image is still encrypted. The encryption key is what turns those sectors back into usable files.
For BitLocker, check the relevant Microsoft account, organisation or printed recovery-key record. For FileVault, the authorised user password, recovery key or configured institutional route may unlock the volume. The exact route depends on how encryption was set up before the failure.
Find the key before spending on recovery
Tell us whether the drive asks for BitLocker, FileVault or another credential. If the key is unavailable, recovering more encrypted sectors may not create a usable result. We do not market password cracking or a guaranteed bypass for properly implemented full-disk encryption.
