I, too, recently had an IDE disk which I wanted to copy data from.  
Unfortunately for me, this disk was in the process of dying.  Many
errors, unfortunately for me, many were in INDEXF.SYS.  These corrupted
headers often would produce unsupported file structure errors when 
accessed.

It was also slow as hell, MONITOR would consistently show it with a queue
length of 149.9 while the output drive was something like .05 on average.
