Hi, i've worked out this is an Acer Cd writer. Problem i'm having is that for the last few months, alot of the cd's i am trying to burn are either stopping mid-burning, and fail, or they burn sucessfully, but their contents might not be able to be read. Doesn't seem to matter what the contents on the CD are, eg Mp3's, .bin or .iso files. Quite annoying. I'm running Windows XP with SP 1. I checked out the Acer site, and it has something about firmware drivers or updating. I downloaded the small firmware detect program but the version it gives me is H.DH, which doesnt appear on their lists. Any help would be much appreciated.
