Are you suspecting the dumped image to be faulty? If so, check the ROM file 
supplied with e.g. VICE or for that matter download ROMs from Zimmers and 
configure VICE to use those instead of the default ones. If the floppy drive 
emulation still works, it possibly can't be a problem with the image data.

Anyway, did your customer use the correct DOS version, related to which 6530 
RIOT chip is inside the drive? I see there are three sets on the FTP:

DOS 2.5
DOS 2.5 revised
DOS 2.7 - Is this for the 8250? At least it goes with a different RIOT.

Best regards
