And it's not saying or doing anything it just randomly reboots? That seems more like a hardware issue than something OS related since the OS isn't even on those disks. If it's just data disks you could unplug them to see if the machine still reboots. That would let you know for sure if they really are the problem or if it's something else. Are you sure the power surge didn't affect the power supply? Also did you do anything to the system after the power surge (like open it up for any reason where there may be a loose wire not plugged in all the way). The last thing I would mention is this could all be a coincidence and it might be related to heat, make sure all your fans are working and that there isn't any big dust buildup inside (gogo compressed air).
