Hey everyone.

I'm having a heck of a time finding information about using CD-RW drives
with SCO unix. The latest thing I found was an article saying that SCO does
not officially support rewritable CD drives. While there is a package
available called CDRECORD, it apparently only works with SCSI drives. Has
anyone out there had any luck with IDE rewriteables? Any help greatly
appreciated. THANKS!

I very much doubt you'll have any luck with an IDE CDRW driver with SCO. Linux
doesn't support them properly (it fact by pretending that IDE CDROM's are SCSI
devices Linux can then talk to them through the "generic" SCSI device driver).

Hold on a minute, SCO supports IDE in a simular way to NT, by pretending that
it is a (weird) SCSI host adaptor. So CDRecord might work after all...

Yer pays yer money, yer takes yer choice...

Cdrecord works only with SCSI drives. Since it's released under the GPL,
you are certainly allowed to hack it to extend its capabilities.

This does not currently work. Support is needed in the wd "host adapter
driver" which provides the virtual SCSI interface to ATAPI devices;
until that's present, you won't get ATAPI CD writing to work.

Sorry, it won't.

However, ATAPI really _IS_ SCSI, disguised behind a layer of cheap
paint. It's SCSI with enough small tweaks that you can't just use it
and expect it to work -- needs specific driver support to do things like
translate SCSI command blocks into nearly-identical ATAPI command
blocks. For IDE CD writers to work, the wd "host adapter" driver needs
to know how to translate a few more blocks. Which I think is being
worked on.
