the CD ROM drive in my notebook computer is having random problems reading data CDs. Often when I put a software CD in the drive the light goes on for some time and then my computer will recognize the CD as an audio CD, with 1 dummy file called track 01. Sometimes it will recognize them no problem. These are all original commercial software installation CDs. I have been experimenting with about 5 different CDs and sometimes the same CD will work fine but later will have the problem described above.
Could this be caused by a dirty lens? I have troubleshooted this by turning off read ahead, reinstalled the master IDE controller, tried in safe mode and also ran the hardware diagnostics program that came with the computer.
