[RndTbl] I/O error with dd

I back up my entire system, including Windows, by copying the entire contents of one drive to another using the dd command (boot to Linux rescue DVD). I have bays that allow me to remove the drives, and after copying father to son I use the son.

During the last backup I had an input error part way through a 100 GB vfat partition. I completed the backup using conv=noerror, and recorded the record number (1MB records). The father drive, containing the error, is a brand new drive.

A windows check of the partition does not reveal any problems.

Presumably, I have a corrupt file on the father, which could be restored from the grandfather. Is there any way I can find which files are on the effected part of the drive?
