You've just been lucky. I forget the exact scenario, but it is something like if journal replay is happening while the RAID is being reconstructed after a crash you can get garbage written to your disk. > Three times in the last 9 months one of the drives reported errors > and dropped offline, each time I have fdisked the bad drive, > formatted it, fsck'ed it and found no problems, fdisked it again, and > raidhotadd'ed it back in and it restored the array without problems. This is probably a matter of block remapping replacing bad sectors when you try to write to it.
