Symptom
You hear a clicking noise coming from the computer.

The reason for this issue in many cases is a head crash or bad head alignment that causes the HD to fail to initialize.
It can happen to a new as well as an old HD, with older drives being more prone to head crashes and head failures.

Symptom
One or more of a RAID array drives failed or the RAID array failed to initialize and you no longer have access to the array data.
Reason
One or more of the HD failed or the array controller failed.
Action
Stop working immediately with the server, number the order of the HD (0,1,2…) and bring that array preferably with the array controller to a data recovery expert.
If the array failed to load, do not try to replace a HD, in case the array did not initialize it would not help and might cause the rebuilding on the array and you could lose the data completely.
Do not try to replace a controller – it doesn’t have the raid information structure of the old one and you might accidentally initialize the RAID array and delete the existing information.
Be advised that most RAID array data losses are caused by human errors.
MEDIA
RAID array (SCSI + ATA + SATA)

Symptom
Backup Tape couldn’t be read by the tape drive or the backup software while performing a restore of a backup.
Reason
Magnetic Tape might be old and has some surface problem.
Action
Bring the Tape for a diagnosis to a data recovery expert.
Please be advised that in some cases it’s easier and cost effective to recover data from damaged HD than a tape. In cases where you are restoring data because of other failed media we would like to evaluate both backup tapes and hard drive.
MEDIA
Magnetic Tape.
