DO YOU(er I mean your friend) HAVE THE CORRECT DISK INTERLEAVE

I have found this to be sooo far off befor that you would do well to check it.

How do I do this??   Spinwrite or the mace utilities Hoptimum will do it
for you......   YOU WILL HAVE TO BACK UP DATA FIRST....

Interleave on 6300s with 40 megers has been in the 4-7 range.  A plus
could  go as low as a 2 interleave.     DON'T assume someone did this
for you.  If you must use external rom code also consider a program
called RAMIT, it takes the romed code and caches it into ram on the motherboard
improving performance greatly..
