Thanks Todd for the reply. There were no sectors remapped, which is odd as there were bad sectors originally on the drive. I ran MemTest86+ out of curiousity, and there are 5120 Errors, some at 0.4MB & 0.5 MB. The BIOS has been playing up, not recognising the Primary Master drive. This is the channel the Hitachi disk was on when it developed the sector read errors. Could a bad controller or bad RAM cause Hard Drive sector errors? The drive is as good as uninstalled, so I may as well send it for replacement. Regards, Keith NB: The box is down now, and I'll try and test and identify the bad memory module next. _______________________________________________ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
