Help updating NEC 3520a Firmware

I have a external usb NEC 3520a with firmware v. 1.04 and would like to update the firmware to the offical release v 3.04 How do I do this? the computer also has a internal NEC 2500A burner installed Thanks :bow:

Probably the easist way to do this is to remove the external drive from its enclosure and place it on an internal IDE channel and flash it there

Thanks Dee but is it possible just to unplug the internal drive and then flash the external usb one with a usb connection

FWIW
I have no problem what so ever flashing with my USB 2.0 external drive. However, I have heard some enclosures are picky and may not flash properly. I think it all depends on the chipset in the enclosure.

I would think the newer enclosures should allow flashing. I flashed my CD-RW and DVD-ROM drives in my USB 2 enclosures. My enclosures all have a NEC chipset.

Thanks all my NEC flashed o.k. as a usb device and now has v3.04
