Here a question that I have about my new drive. NEC has this website http://support.necsam.com/oem/cd-rom/ND3540A.asp and logically, that is where the firmware should be found for my drive. However, when clicking on the Firmware Updates link, in the result list I do not see 3540A listed. Is it because the drive is OEM? Should I use the firmware from the 3520 or 3500 drive?
