I am experiencing this problem with my CD-R/W driver. I have windows XP and 2000 both installed on my system. The CD Drive is visible from windows 2000, but when i go to windows XP, i dont see the CD Drive there in My Computer. It used to be there earlier, but then it disappeared. Normally when some bad CD is inserted, it disappears ,but it appears again on restart. Now its not appearing altogether !!! I know that its driver is the cause. Will I need to download a driver for it ? What might be the reason? Howcome it is functioning okay in Windows 2000?
