Red Hat Bugzilla – Bug 125202
cdrecord --scanbus doesn't find SCSI-CD-Writer
Last modified: 2007-11-30 17:10:44 EST
Description of problem:
My TEAC R55S SCSI CD-Writer works fine with Fedora Core 1.
devices: see attachment 1 [details]
Fedora Core 2 also recognizes the CDROM-drive at /dev/scd0 (CD-reading
works fine). But cdrecord only recognizes my ATAPI-CDROM, which isn't
a CD-Writer: see attachment 2 [details]
I have tried serveral former Versions of cdrecord (also the one
included in Fedora Core 1) whitout success.
The main problem seems to me, that there are no sg-scsi-devices:
...no result (successful in FC1, see attachment 1 [details])
I can find the CD-Weiter in the sysfs:
> cat /sys/bus/scsi/devices/0\:0\:3\:0/model
> cat /sys/bus/scsi/devices/0\:0\:3\:0/vendor
To resolve the problem. I made a link:
>ln -s /dev/scd0 /dev/sg0
0,3,0 3) 'TEAC ' 'CD-R55S ' '1.0R' Removable CD-ROM
but it still doesn't work, I get the follwoing error:
see attachment 3 [details]
Version-Release number of selected component (if applicable):
all cdrecord 2.x-versions an FC2
Steps to Reproduce:
1. cdrecord -scanbus
see attachment 2 [details]
Created attachment 100838 [details]
attachment 1 [details]: FC1-devices
Created attachment 100839 [details]
Created attachment 100840 [details]
attachment 3 [details]: cdrecord result
can you try:
# cdrecord dev=/dev/scd0
Created attachment 100852 [details]
attachment 4 [details]: output of 'cdrecord -v dev=/dev/scd0'
I already tried 'cdrecord -v dev=/dev/scd0' - with the same result (see
attachment 4 [details])
My Yamaha CD-Writer on the SCSI bus works with dev=/dev/scd0, although
it should be recognized with simple -scanbus it always works that way
but not on the FC2.
should work again with kernel 2.6.6

cdrecord --scanbus on kernel 2.6.6
I just updated the kernel to 2.6.6 and it works fine.
Thanks a lot.
