What does cdrecord --scanbus tell you?

Well, I can honestly say this isn't how Linux handles CDRWs... I've
been using them for at least 2 years now under Linux, ranging from my
first Yamaha SCSI burner to my more recent IDE Ricoh
relatively-generic CDRW.  Works like a champ all the time.  I've maybe
mis-burned a dozen CDs under Linux in 2 years and probably close to
2-3 dozen under Windows.

Does the CDRW work as a normal CD-ROM fine?  Ie. you can mount/umount
normal CDs and such under it?

hde sounds to me like an ATA100 controller.. do you have it on one?
Can you perhaps put it on the motherboard's ATA33/66 controllers?
FYI, I have a promise ATA100 card here with four drives (all ATA100)
on them, and my CD-RW is hda, and the only device on that bus.  It is
also ATA100, but perhaps your difficult is in having the CD-RW slaved
to an ATA100 drive?

Not much of a bone, but possibly worth investigating.  Of course, I
could be *way* off here...
