I was wondering if it was possible to make this drive accept 700mb disks. I can only use 650mb.Thank's

Hmmm that is very unusual these days!
The only way would be via a firmware upgrade if it's available. But how old is this drive? As most anything made within the last 2-3 years will do 700/80 CDR's

Hey pimpsta,
Got the same burner mate and only use 700mb discs, haven't downloaded any firmware updates so don't know why yours won't burn em.
I know its not much help mate but at least you know it can be done.
Mine won't touch datasafe discs, is yours the same??
