Rod, Microstudio requires an ASPI driver to be installed on your computer that identifies your CD-Recorder (either IDE or SCSI). I expect when you installed Win2000, your ASPI driver was modified, causing the problem. Click the Search button at the top and enter ASPI to see all the posts about this topic. If you still have problems, post a new reply under this thread.
As to unsuccessful write operations, the Installation Guidelines you were required to make to your computer when installing Microstudio have probably been undone by installing Win2000. You can find these on our website at:
