| Re: DVDRW Turns Into 'CD Drive'
Is this a new brand you're trying? I had a similar thing when I brought Tesco DVDs. Problem solved when I used a proper brand.
If you have XP, then you cal also fall back on system restore after the other stuff is exhausted. You would just need to restore the system to before the changes occured.
START > Accessories > System Tools > System restore
just incase you're not familiar with the feature |
