RE: rebuild kernel or get new hard drive?

If you reboot from the console, on startup, it will ask if you want to
run fsck on the drives.  Answer yes. If you are running raid disks, it
should repair any problems if it is simply a bad spot on a disk.  If you
are not running raid or only have one disk, your problem will probably
be more severe.  If it is a bad spot on the hard drive, you might be
able to reformat that partition.  If the partition is root or usr, you
may need to rebuild the machine from scratch.  This will allow you to
run a reformat of the entire disk to fix all bad spots.  It may be that
the disk or its controller are bad and that would mean replacing it and
starting from scratch.

Good Luck.
