I built a computer at home and setup a RAID 1 array with 2 sata drives. One of the drives was in a removable tray that I could take out when I shut off the computer for a backup. Everything worked fine until the other day, the drive in the removable tray crashed. I took it out and reset the computer and got a message that said "Too many cold boots" but managed to boot the computer up using the other drive. I can't even access the removable drive anymore. I am a total newbie at this so was I using RAID in the wrong way or did the drive just screw up?
