CDRW suddenly stops working til reboot

after using my cdrw drive once per restart, the drive suddenly stops working (it disappears from “my computer” and the power doesn’t work), it will not even let me eject,
I need to reboot to get it working again…can someone help?
it does auto detect on the bios and when i goto secondary ide drive it does appear as master in “DMA 2” mode, and there is no slave on the secondary.
I think this only started to happen after reinstalling winxp
