The result was usually system hangs and this was with kernel 2.6.17.13. I upgraded to the latest production 2.6.20 kernel and experienced the same behaviour. I've tried to recondition the drive with dd writes to force reallocation but there are still read errors (appearing at other addresses) - anyway, the drive is bad, the point is there is a problem with how it is handled and I was starting to suspect my hardware, however I got this while trying to backup the array (which was fully sychronised - eventually) it appears it hit another read error. Note I'm using PATA drives on with a promise IDE controller (using the sata_promise module). Please investigate / let me know if you need more info and can help me out here. Thanks.
