For some reason whenever i put in a +R disc into my 3500AG it says it sees it as a writable disc. but never can burn. the extremely strange part is when i put a DL disk in it shows the free space on that disc as being 3.99g(vista). This happens even if i put in a correctly burned DL disc. I've tried all different firmwares. I was originally on 2.16, upgraded to 2.18, then 2.19, then 2.1A. I just installed Liggy/Dee's 2.TG. Havent had a chance to try this yet. Is this something anyone else has seen. only being able to see 3.99gigs free on DL media even if the media has been burned successfully.
