I have RAID 5 with Three Hard Drives. This is a Dell PowerEdge 1750 with PERC 4/DI.
One of the drives is failing on an important server. In RAID I see:
Array Disk 0:0 Failed SCSI ProductID Rev0003 Seagate 136.63 GB capacity
Array Disk 0:1 Online SCSI ProductID Rev0003 Seagate 136.63 GB capacity
Array Disk 0:2 Online SCSI ProductID Rev0003 Seagate 136.63 GB capacity
I am not sure why the disk failed, but in Windows Server 2000 I see

Questions:
1) Should I rebuild the one failed drive, and then put it online?
2) Or should I buy a new hard drive and hot swap it?
3) What's the worse that can happen?
Doesn't the new drive need to be have NO metadata on it?
Antzs - RE: If the disk already failed, rebuilding it would not be successful anyway. It was still fail again.
The disk failed after I rebooted the server. How can I be sure it's a hardware fail and NOT a software corruption fail?
What's the worse that can happen if I rebuild the failed hard drive? See http://prntscr.com/evbuv6
