If there is physical damage to the hard disk drive, the drive may not decrypt completely or may be unusable.

If there are bad sectors in the hard disk drive, Endpoint Encryption will attempt to skip the bad sectors during decryption, which will lower performance depending upon the amount of bad sectors. If the bad sectors are in critical locations, the hard disk drive may be unusable.

Make sure that the hard-disk drive cable is properly connected before booting from the Repair CD
