If you are running a system based on the Epox 8RDA+ mainboard, you are probably experiencing the NForce2 bug (not a hardware bug, it is a driver bug).
Many ppl had this problem. If you revert the IDE driver of the writer's channel back to the MS driver, instead of the NVidia driver, all problems should be gone.
This is a wellknown error and most likely to be solved in NVidia's Nforce2 drivers version 2.04.
I own a NForce2 board as well (MSI K7N2G-ILSR) and I had similar problems, but with Windows 2000. For me, installing the NVidia drivers worked, but this seems to be quite odd. For the best: use NVidia drivers for your HDD and MS drivers for your CDRW drive.
Try it, and rapport back
