Using Intel Matrix late last night I got an error that one of my drives failed. I quickly replaced the drive and the array rebuilt fine. Before RMAing the drive I figured i'd give it a test and hook it up to another PC. I was unable to access the drive at all or even format it but I decided to give it a try as a boot drive and install an OS on it forcing it to format. The drive now seems to be operating normally... I'm so confused why this would happen. Is it typical that a drive fails but isnt dead? Is it safe for me to re-insert the drive back into the array?
