ATAPI cdrecord issue 2.5.67

[Grzegorz Jaskiewicz]

I noticed strange bahavior while truing to record CD using ATAPI on
2.5.67 kernel:

bash-2.05b$ cdrecord -scanbus dev=ATAPI

Well, FAKE non CCS disk ?
i have on this port Sony CDRW :

bash-2.05b$ cat /proc/ide/hdd/model
SONY CD-RW CRX215E1


2.4.21-pre7 still is able to see this drive and i can record CDs on it.
2.5.67 failes.

it works fine if i will do dev=/dev/hdd
but still output of cdrecord is supprising to me.
Also after inserting ide-scsi /dev/scd* nor /dev/sg* apears.

Well, that is allright. Just wondering about this -scanbus message :-)

You must use /dev/hdX device naming convention:

cdrecord --device=/dev/hdd -inq

At least, it works fine for me :-)

ide-scsi is still broken in 2.5... don't know if it's gonna get fixed or
deprecated as ATAPI support is working.

I don't like ide-scsi, but I need to use cdrdao to burn vcds. I wish
someone would patch it to support 2.5.x ATAPI.

And far longer than that. People seem to be testing and demoing 
crazy things like SATA attached scanners, printers and even enclosure
services.

ide_scsi for 2.5 is about item 5000 on my list of things I care about.
The core reset code is now close to right (one race I don't understand)
so it should be possible to fix the 2.5 ide-scsi code (maybe by porting
the perfectly workable 2.4 code again 8))

I think ide-scsi needs to be supported for some time going forward.
After all, cdrecord, cdrdao, dvdrecord aren't going to be the only
applications.

ATAPI tape drives will need ide-scsi too, unless ide-tape somehow
got repaired lately. And some people already use ide-scsi+st in
2.4 since ide-tape doesn't always work reliably.

ide-scsi isn't just for CD/DVD writers.

How long will it be before somebody develops an ATAPI, SCSI host
adaptor, I.E. a SCSI host adaptor which appears as an ATAPI device?

(I know that ATAPI really is effectively just a SCSI transport, but
you can already get SCSI, SCSI host adaptors, I.E. where the devices
on the second-level adaptor appear as the logical units of the host
adaptor, and there is no reason this couldn't be done using ATAPI).

John.

Whan I last looked at the ide-tape driver  , which was
back in 2.2, it looked like the big problem was actually 
in it error handling , rather than anywhere else.

I don't think it has been changed significantly it that regard
since.

IIRC , the behaviour which appeared to be caueing me a problem
was that some slow driver would be busy long for ide-tape to
get bored. It also didn;t like getting error codes which weren't
spelled out it the quik spec. The common travan mechanism I
get lots of here, spits out quite a few of those. (As well
as failing one of st's enquiry cmds).

Just to add to the list, I have an ATAPI MO drive that only works with
ide-scsi and not with any native IDE driver.
