The disk has NO bad sectors. It has been checked using two different tests.
1) seatools (The seagate test tool passed the deep test where it reads

2) dd of the entire HD image onto another HD.
No sector errors were encountered in either case.

No, this is Linux kernel 2.6.15.1 with no patches.

I cut and pasted the Linux version number to the top of each trace 
output in my original email.
