Example repair-bde command

In this example, a user tries to edit drive C and writes the contents from drive C to drive D using the recovery key file (RecoveryKey.bek) stored on drive F and writes the result of the test. this into the log file (log.txt) on the Z drive.

 repair-bde C: D: -rk F: RecoveryKey.bek -lf Z: log.txt

In this example, a user tries to edit the C drive and writes the content on drive C to drive D using the specified 48-digit recovery password.Recovery passwords must be entered into 8 blocks of each six-digit block with hyphens to separate between blocks.

 repair-bde C: D: -rp 111111-222222-333333-444444-555555-666666-777777-888888

In this example, a user forces the C drive to be removed and then tries to edit and write content on drive C by using the recovery key package, and the recovery key file (RecoveryKey.bek) is saved. stored on drive F.

 repair-bde C: D: -kp F: RecoveryKeyPackage -rk F: RecoveryKey.bek -f

In this example, a user tries to edit the C drive and writes the contents from drive C to drive D, he must type the password to unlock the C: drive when prompted:
