Sorry to be so dumb but what is t43 ?

Usable ? Does it boot at all ? how far does it get ?

This seems reasonably common, even when there is no problems that I can 
see with a machine. When using parted, the error message is:
(parted) print
Warning: Unable to align partition properly. This probably means that 
partitioning tool generated an incorrect partition table, because it 
didn't have
the correct BIOS geometry. It is safe to ignore,but ignoring may cause
(fixable) problems with some boot loaders.

Bad blocks on the disk. Usually the drive is designed with reserve 
space, that is normally inaccessible. When a failing sector is detected, 
smart can remap the bad block to the reserve area (and lets you know 
about it). Sometimes this is indicative that the disk is beginning to 
fail - especially if more and more sectors show up as bad over time.

back it up to some sort of removable media using:
dd if=/dev/hda of=/root/mbr-backup bs=512 count=1
then you could use a rescue disk to reapply the backup attempts to fix 
are not successful.

I would be making a complete copy of the disk to another drive, in case 
there is information that you want, just in case the disk goes dead.

Without more info from you I suspect you would be getting less than 
optimal advice!
