The problem is that cdrecord is not able to detect my drive correctly.
I have modified a bit the cdrecord source and got the -scanbus command
to work. I have also traced the problem to the pg.c source.
All the information I got is below. I hope somebody can shed some light
on this.
Below you will find the output of the command 'insmod pg' and 'cdrecord
-scanbus'.
I changed the source (libsgc/linux-scsi-pg.c) so that I skip the call to
write() in the function do_scsi_cmd() when sp->size is zero. With that
modification the inquiry information is received and shown alright but
nothing else (but -scanbus) works.
When sp->size is zero inside do_scsi_cmd, inside
drivers/block/paride/pg.c, at pg_command() dlen is also zero and that
causes and error. At the end of the message you will see the debug
output of pg.c (with a small change, to print just the dlen characters
on output) while cdrecord tries to do a -scanbus.
I think there is something illegal about dlen being zero in pg_command,
but I don't know what it is. I am sure somebody who know about ATAPI
and paride can find out the problem.
In case you wonder I have also sent this information to Joerg Schilling
(cdrecord's author) and am still waiting for his answer.
My configuration:
Cdwriter: HP CD-Writer+ 7500e
System: Debian 2.1 (Slink)
Kernel: 2.2.9
Cdrecord: 1.8.a20
With 1.8.a22, the version I modified the source of, the results are the
same.
Eduardo.
