I don't have your specific hardware, but I have a Yamaha CRW4416S
rewritable CD device, on an Adaptec 2940UW HBA which also gets weird
sense errors, has problems writing a CD successfully, and has trouble
even reading standard audio CDs. The details of which I posted to the
list about a month back.
I know that there are some obscure firmware problems with the 4416S, but I
suspect the SCSI driver software in Linux to be the culprit in this case.
Certainly, this bit of sympathy is falling short of the answer you were
hoping for. Some consolation that we have the source code, but, I have
other software to develop, and debugging device drivers code that should
be stable is at this point more of an irritation than a challenge,
admittedly.
