Well, y'all, to continue this little discussion Fernando asked what the exact error I got was, when I was trying to REINSTALL RedHat - it was: Invalid argument during seek for read on /dev/hda I actually gathered up backups (what I had) and swapped drives around, put the drive in question in another machine as slave, the machine booted fine of course but this drive failed to mount, and Gnome's hardware browswer showed the drive, but the root partition said "no filesystem" Then I swapped some more and it now sits alone in a machine, and I'm attempting to wipe clean and install Red Hat, and I'm getting the above error periodically during the preparation stage (before you actually click "install") Sounds like bad disk to ME - but I'm going forward with the install just for fun. Told disk druid to check for bad blocks. Is this going to format the drive, low level format, or just? what? - i dunno what other options I would put in that list *laugh* fun fun fun
