This disk is bad, as can be seen from

    5 Reallocated_Sector_Ct   0x0033   253   253   063    Pre-fail 
Always       -       1
197 Current_Pending_Sector  0x0008   252   252   000    Old_age 
Offline      -       16
198 Offline_Uncorrectable   0x0008   243   243   000    Old_age 
Offline      -       10

These errors (partilculary those indicated by the last 2 lines) are 
definitely responsible for the messages in the logs, the filesystem 
corruption, and data loss.

There are Maxtor tools (at their webpage) to re-initialize the disk, and 
if you're lucky, the disk will be good the next 10 years. But the errors 
might as well show up again soon. So I'd return the disk if the data on 
the disk are important to you.

smartctl -a -d ata /dev/sda gives you all the info, including the info 
on the progress of the selftest.

HTH,

Kay
