Identify file(s) on specific disk sector



When tar'ing up an ext3 filesystem on a 3ware RAID I have, I got
the following errors in my system log:

Apr  7 21:27:46 allo 3w-xxxx[957]: Drive error encountered on port 3 on controller ID:0. Check cables and drives for media errors. (0xa)

The tar command itself reported no errors.  Neither are there are ext3 fs
errors in the log.  But the disk errors seem to imply to me that there is
possible file corruption.  Is there anyway to identify which files are
sitting on the above sectors of the disk?
