I decided to update the firmware on my NEC3520A from 1.04 to 3.04. I got the updated firmware from the NEC site so it is an official firmware update. I used a Windows flash utility that came with the updated firmware and it confirmed that I had an NEC3520A with firmware 1.04 and asked me if I wanted to flash it to 3.04. I chose yes and it started to flash but then a message came up saying there was an error so I cancelled the update. I noticed the light on the drive flashing so I left it for a while but it continued to flash so I rebooted the computer.
Now the drive does not work properly but the firmware is still recognised as 1.04. I tried flashing it back to the original 1.04 firmware but it failed to do it from Windows. The only thing I can think of now is trying it from dos. My drive was not the boxed retail version coming in a plastic bag with a software CD only. Could it be that a cheaper non-boxed bare bones drive requires a different firmware?
The drive could still be saveable as the firmware is recognised and it still partially works. According to the NEC site I got the firmware from I flashed it at my own risk so I have no come back with NEC even though I used their official firmware. I suppose I could still return it claiming it just stopped working properly but I want to see if I can fix it myself first. I have updated firmware on other drives before and never had a problem and have no idea why it failed this time. Any advice before I attempt to restore the original firmware from dos would be appreciated.
