There are a couple of cases where you can see bad block errors on a good drive. If a block is written with a bad CRC for some reason...the write head got a freak blip or it lost power as it was writing, or the data went corrupt while sitting on disk, then it will read as a bad block, but rewriting would fix it. A RAID media verify or a badblocks -n run can usually fix these. -- Zan Lynx <zlynx@xxxxxxx>
