I haven't tried any other Maxtors. The eeprom on the HMHDS1 requests a specific drive, but whether there is any latitude- ie how similar these drives are to the models JVC use I don't know.
Perhaps the Geert Jan would have a better idea what the eeprom code is set to look for.
no problem, it was just a thought, i didnt bid on it anyway, 40GB is a bt small as spare drives do these dyas, so if it doesnt work in the JVC then it's a bit redundant to me :p
