tnx Chuck and everyone for the tips. Actually sorry for using msdos as a sample, but I knew that probably was a bad example to use and should have stuck with iso9660. Sorry about that I knew when I sent that I probably chose a bad choice for command line example. In any case I'll check to see exactly where things are pointing. I could even have a jumper problem. I checked to be sure it was set as master and save cause one drive got upset over cable select. However, worth just double checking that if I find referencing hdc or hdd doesn't work. tnx
