If Nero shows the following error message on drag&drop of audio files:
Unfortunately Nero can not determine the SCSI/Atapi device belonging to the drive letter.
then presumably one of the following reasons will apply:
Unfortunately this is not possible. Currently it is only possible in Nero to draw audio files over from the CD-ROM drive
If you do not have a CD-ROM drive or the reading quality of the CD-ROM drive is bad, then you can only use CD recorder -> track saving to create an Audio CD which is to have tracks from various CDs. At the moment unfortunately there are no plans to use CD Writer to read audio tracks from.
HKEY_CURRENT_USER\Software\Software\Ahead\Nero - Burning ROM\General\SpinDownSeek
Set the value to 1.
If you are working in Windows NT and when starting Nero do not get an error message regarding missing Nero driver, then the Nero driver is not recognizing your CD-ROM drive correctly. We do not know why this phenomenon (rarely) occurs and do not know of a solution to it. As a driver is being developed for Windows 2000 at the moment which will also work in Windows NT4, we can currently only ask you to wait until then. The Windows 2000 driver will presumably be available at the latest when Windows 2000 appears.
