Apologies I am new to this. Just got a new sony CRX230ee (cd-rw drive) and installed the hardware without too many probs (apart from one BSOD about ‘not enough irp stacks’ which seemed to fix itself). The drive is defaulted to 40x burn and read speeds. I use Nero 6 to burn and it recognises the drives speeds. However whenever I insert media to burn to it will only burn at 12x? obviously would like to be able to use the 40x possible burn speed (52x when turbo). The media says it is ok upto 52x and I’ve tried afew different kinds, same prob. Tried media in other PC’s and allows full speed burn. Can anyone help?
