Hi there, IM GOING MADDDDD!!!
I just got myslef the nec 3520a a few dayz ago, it as working perfectly fine, its on the secondary IDE channel as Master no slave, and in UDMA 2 mode.
Today I flashd the drive with the new beta patch, after doing this I'm now getting Device Buffer problems in whatever burning program I use, it just dropz and rises every few seconds causing the burns to be VERY VERY slow, when choosing 12x or 8x etc, the burns max itself to 2.4x and doesnt go over.
Im uninstalld the IDE and reinstalled, changed the IDE cable, updated my IDE drivers, and uninstalled them back to normal window drivers, and STILL i get this same problem.
WHAT CAN I DO??? This is doing my head in.
