I think it has screwed me a bit already, but then, I didn't check until recently. I didn't even know about this "feature". But doesn't help much when those "badblocks" are recorded already. What would be the official way to remove them apart from rebuild the whole array? A friend of mine wrote a thing in python to remove the badblocks list from an offline array. I haven't dared to test it on a live system, but apparently it worked on his (5 drives in RAID-5 IIRC with three of them showing a list identical of badblocks).
