I have a Windows 2000 system that the CDs are recognized on. They disappeared after a software upgrade which was supposed to make the CDRW write rewriteable media. The drives are seen by the hardware and can be used to boot the system from CD. I have uninstalled the software, the drivers and reinstalled them both manually and with the new hardware wizard. Nothing makes them recognized.
In the event log I see an error that says aspi32 service failed to start due to the following error: The system cannot find the file specified.
I copied the cdrom.sys from a Windows 2000 system which has the same configuration and did not have the upgrade software installed, but that didn't help. I also checked the working system and it does not have the aspi32.sys file or any other file with that name.
My last attempt to get the drives recognized, I booted the Windows 2000 CD and repaired the installation, but that didn't work either.
How can I get the CDs recognized without reinstalling Windows 2000?
