As part of this they replaced the motherboard, and realised that the new motherboard had one fewer SATA connector than the old one. They got very concerned, until they noticed that one of the drives in Web at the time wasn't actually in use at all, either as part of the RAID array or otherwise mounted, and Web seemed to work perfectly fine without it. This drive was labelled the "mystery drive" and put in Marks' pigeon hole. | ||
What the crew hadn't realised is that this drive ''was'' probably part of the array, until it had presumably failed some months ago (that's probably what all those emails were about...) - the array kept on keeping on, as a RAID-5 is meant to, but they were now one drive failure away from disaster. | What the crew hadn't realised is that this drive ''was'' probably part of the array, until it had presumably failed some months ago (that's probably what all those emails were about...) - the array kept on keeping on, as a RAID-5 is meant to, but they were now one drive failure away from disaster. | ||
