If it starts to number from the parameters it is parameter byte 9 which is the low byte of the maximum pre-fetch. Can you edit the modes and write them out if you don't change anything? If you can't we have a bigger problem with this drive. Peter -- Peter Dufault Real Time Machine Control and Simulation HD Associates, Inc. Voice: 508 433 6936 dufault@hda.com Fax: 508 433 5267
