I have got an NEC DVD-RW ND-3520A drive installed. It plays DVD's ok and records dvd-r's and rw's ok. However, whenever I put in a blank CDRW the pc thinks the drive is a CD Rom only and will not allow any recording what so ever using any software. I have reason to believe that the driver got ruined when I installed a very cheap burning software which created a virtual drive. I have tried rolling back drivers and updating drivers to no avail. Can you help as I am on the brink of restoring the PC to return the drive to normal. I have an AMD 3000 processor, Windows XP, 1 GB ram. Anything else you need to know? Thanks for your time.
