Re: ide-scsi -> write_g1: scsi sendcmd: fatal error

Something like this ?

scsibus0:
        0,0,0     0) 'TSSTcorp' 'CDDVDW SH-S203B ' 'SB00' Removable CD-ROM
        0,1,0     1) *
        ..

(This is a SATA attached drive. It appears
  as SCSI without ide-scsi emulation.)

Then try
  cdrecord dev=/dev/sr0 -dao ...
rather than
  cdrecord dev=0,0,0 -dao ...

This is deprecated too. But maybe it works.
I understand that cdrecord uses /dev/sg*
if you give it dev=0,0,0.
(We have a wealth of SCSI drivers in Linux.)

That's normal. There are two sects of distro
makers. Yours are in favor of "sr", others
prefer "scd", generous ones provide both.

That is really strange. I got 15 files below
/proc/scsi. Like:
  ./scsi/usb-storage
  ./scsi/sg
  ./scsi/scsi

I do not have a system with no (pseudo-)SCSI
devices. So i cannot tell whether the lack of
/proc/scsi is normal.
(On the other hand /dev/sr0 works for eject.
So somehow the system knows the drive as SCSI.)

Do you have any USB device attached ?
Usually they should show up like
  /proc/scsi/usb-storage/85
  /proc/scsi/usb-storage/28
  /proc/scsi/usb-storage/21

What do you see if you boot without ide-scsi ?
Do you get a directory /proc/scsi then ?
(Could it be ide-scsi confuses /proc ?)
  

Well, if no more insight can be gained, it
is time to ask some kernel people. I would
first try at Gentoo, because as said: ide-scsi
is not advised for 2.6 kernels.

At least one can ask why /proc shows no signs
of scsi info.
(If you meet unwillingness to deal with cdrecord,
i could offer my own burn program cdrskin for
testing.)


Have a nice day :)
