One of my hard drives in my raid is failing, so I took it out, bought a new drive of the same size...but when I put it in place of the failing drive and mark it as a spare, it doesn't rebuild...There is no options to rebuild either...Please help!
Thomas. Andrews, it is very important to know which type of RAID did you set up? RAID 0, RAID 1 or RAID5?
Please access the onboard RAID BIOS and check the status of the RAID. If it is degraded you should be able to replace the defective hard drive and rebuild it. There is a 50/50 chance the RAID could be rebuilt without problems.
If the RAID status is failed, that means that the structure was corrupted since the beginning.
Which Operating System are you using? Where you installed it?
