When I insert a cd rom into my combination drive it will not read the contents of the disc. My PC uses XP home and Device manager reports that the drive is working ok. If I un-install the driver for the HL-DT-ST RW/DVD GCC-4320B drive and reboot, everything works fine until I next switch on. I then have to repeat the driver removal again. The Drive is the only one connected to the Ide cable, Any one come up with a cure for this problem?
