A decent UPS can help here. >It depends on your exact situation, I was just pointing out that SW RAID >doesn't cover all the bases HW RAID does. If the disk is dead then the BIOS will skip it and the system should boot normally (I've tested this by pulling a disk since I didn't have a suitable dead disk to hand). A hard error in the 2nd stage boot loader, ficl or the kernel is definitely the worst case - I agree that this is very difficult for software raid to recover from. Note that even with hardware raid, there are still lots of failure points. The least reliable parts of a current computer are the CPU and PSU fans, not the disks. -- Peter Jeremy
