[mythtv-users] Need help interpreting hard disk error messages

I have my O/S and original /video partition on a PATA harddrive that
is reporting errors with smartd and logging messages in
/var/log/messages, but I'm not sure where the problems lie (in a
particular partition?) and how to fix them (if they are repairable).
This may only be the result of transient problems I had with a loose
power connector for the drive, or these may be precursors of a
meltdown, so I kinda would like to know how big a cesspool I'm about
to step into.
Here is a sample of the messages in /var/log/messages:
Aug 24 09:33:56 localhost kernel: end_request: I/O error, dev hda,
sector 397318809
Aug 24 09:33:56 localhost kernel: hda: dma_intr: status=0x51 {
DriveReady SeekComplete Error }
Aug 24 09:33:56 localhost kernel: hda: dma_intr: error=0x40 {
UncorrectableError }, LBAsect=397318823, high=23, low=11442855,
sector=397318817

Aug 24 09:33:56 localhost kernel: hda: dma_intr: error=0x40 {
UncorrectableError }, LBAsect=397318823, high=23, low=11442855,
sector=397318817
Aug 24 09:33:56 localhost kernel: ide: failed opcode was: unknown
Aug 24 09:33:56 localhost kernel: end_request: I/O error, dev hda,
sector 397318817
Aug 24 10:02:57 localhost smartd[3470]: Device: /dev/hda, 71 Currently
unreadable (pending) sectors
Aug 24 10:02:57 localhost smartd[3470]: Device: /dev/hda, 31 Offline
uncorrectable sectors
I suspect these relate to the original /video partition because I have
a couple of recordings that I cannot copy off to the current /video
partition on a new SATA harddrive. It is possible that there are more
files elsewhere; I just don't know.
In addition, "fdisk -l /dev/hda" reports this:
Disk /dev/hda: 250.0 GB, 250059350016 bytes
255 heads, 63 sectors/track, 30401 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Device Boot Start End Blocks Id System
/dev/hda1 * 1 13 104391 83 Linux
/dev/hda2 14 30401 244091610 f W95 Ext'd (LBA)
/dev/hda5 14 1580 12586896 83 Linux
/dev/hda6 1581 1841 2096451 82 Linux swap / Solaris
/dev/hda7 1842 1906 522081 83 Linux
/dev/hda8 1907 30401 228886056 8e Linux LVM
and /dev/hda8 is the original /video partition. Doing a little math,
I come up with 30619638 sectors used for the partitions before hda8,
and all the messages pertain to sectors above 397,000,000.
Is this something I can fix using qtparted to reformat the original
/video partition (now mounted as /vidArch)? Do I need to use fdisk
and/or mkfs? Abandon ship and get another disk?
Somehow, I get the sinking feeling that this is a problem at a lower
level than partition formatting and the disk might be about to go
belly up.
Any advice would be appreciated.
Craig.
