I had the same problem but downloaded some of the firmware on the site, I had successfully flashed other drives before and wasnt too concerned but ended up changing my NEC ND 4550A to be named ‘Mad Dog’ something or other.
Now it seems to be named ‘NC3220M TAJ303Z SCSI CD Rom device’ I have tried running the only .exe firmware flash but that now can not see the ND 4550A, presumably because of the name change.
I am not knowledgeable at all about how these work but really just want a link to a simply run file that will flash the firmware, restore the correct settings but also make the drive multi-region.
If that isn’t possible is there a way of returning to how it was as it seems to have problems burning, probably because it has the wrong firmware now.
This is my first post on the forum so apologies if this is put in the wrong place or was answered recently, I couldn’t find anything obvious, and I’m the sort of person that needs it to be obvious.
