Recovering data from a failed SAS drive? (RAID0...yes, I know)
Solution 1:
It depends on how the drive failed. 72GB 10k disks haven't been manufactured for years, so I'd suspect that your disks are at least 6 years old... possibly 9 years... You may have a mechanical problem with the disk.
The server you're talking about is an HP ProLiant DL360 G5. They were sold from 2005-2008.
Running RAID 0 is a calculated risk. Your data was striped across disks, and the failure of one renders the logical drive unusable.
You do not have any options to interface with the drive using a USB adapter. This is a SAS disk and protocol. It won't work.
If you haven't yet. Turn the server off. Let the drive spin down. Then power on and see if you can at least get it to be recognized by the controller.
If the data is important and it's just a mechanical failure, a data recovery firm may be able to help.
