I have a Dell Dimension DIM2400, XP Home Edition. Version 2002 w/ service pack3. Device Manager sees the CDROM and says it is working properly, but it is not. CDROM/DVD is a TSST corp CDRW/DVD TSH492B. It will play a music CD once in a while, but when I put in a program CD or a picture CD and go to the "D" drive on my computer, it shows nothing on the CD. I went through all the trouble pages w no fix. I did the driver updates and it says I am current. Thanks for your time.
