Re: Please help with CD writer questions
I've had a lot of trouble setting up IDE writing systems. I just had one
system I was working on at my work, where the customer wanted an IDE
cd-rewriter working under NT and Linux. Found out that NT wouldn't use the
IDE writer, even after the drivers for SCSI emulation were installed.
I did get it to work with 2.1.125 kernel with IDE-SCSI emulation, but I
couldn't get either the writer or the reader to read or play audio CDs. I
also couldn't get the reader to use IDE and the writer to use SCSI
emulation.
I ended up swapping it with a SCSI writer, which reads and writes audio.
Still can't get the IDE to read audio tracks. Even though the drive says
it can handle CD-DA. Also have the reading problem on my own system. Any
ideas to fix it?
email, please. This list is very spammy for me.
