This is similar to my dad's failed CDRW unit. I replaced the drive.
Here's how to test the drive prior to replacement.
1. Power down. Use the manual eject hole to open the drive door so we know it's not jammed.
2. With power off, remove the wide IDE cable from the drive.
a. Power up. (no need to boot the OS!)
b. Tap the drive open button.
If the drive fails to open, it's dead or not getting power.
Tell what you find out from this test.
Have managed to solve (through the help of Windows ME forum)an IE WMPDXM problem, caused when reinstalling windows ME after a failed attempt to intall IE SP1 - only symptom left is that my CD R/W no longer works - to be honest I haven't used it for a week or two, but now it doesn't even appear on the DEVICE MANAGER under CDROM - and no response when I press the buttom to open it - my CD Writer software also says there is no compatible device - any ideas?
