Re: plextor PX-716A: OPC error, COMMAND SEQUENCE ERROR [growisofs]
A summary of my tests:
===== 1) I couldn't make dvd+rw-tools work with the 1x DVD-RW media I got.
dvd+rw-format [-blank[=full]]-> SK=5h/ASC=27h/ACQ=00h
growisofs -> SK=5h/ASC=2Ch/ACQ=00hù
I think this has to do with blanking since I got the same error with
cdrecord if I try to use a DVD-RW without blanking:
status: 0x2 (CHECK CONDITION)
Sense Bytes: 70 00 05 00 00 00 00 0A 00 00 00 00 2C 00 00 00
Sense Key: 0x5 Illegal Request, Segment 0
Sense Code: 0x2C Qual 0x00 (command sequence error) Fru 0x0
Sense flags: Blk 0 (not valid)
However, I tired blanking the DVD-RW with cdrecord and then
$ growisofs -dvd-compat -dvd-compat -Z /dev/cdrom=test.iso
Executing 'builtin_dd if=test.iso of=/dev/cdrom obs=32k seek=0'

:-[ PERFORM OPC failed with SK=5h/ASC=2Ch/ACQ=00h]: Input/output error
growisofs wll work with 4x DVD+RW media
===== 2) cdrecord-prodvd-2.01.01-i686-pc-linux-gnu
It works with both DVD-RW and DVD+RW media.
===== 3) cdrecord-2.01.1-5 (rhel4 recompiled on rhel3)
It works with both DVD-RW and DVD+RW media.
It reports confusing messages about BURN-Free (I always use
driveropts=burnfree)

==== 4) http://people.mandrakesoft.com/~warly/files/cdrtools/
As far as I can see these patches are the ones the rhel rpms are based on.
It seems those at the site are newer than the rhel ones.
I used cdrtools-2.01.01a01.tar.bz2 as a base.
and added
cdrtools-2.01.01-dvd.patch.bz2
cdrtools-2.01.01-warnings.patch.bz2
cdrtools-2.01.01a01-scanbus.patch.bz2
Couldn't use cdrtools-2.01.01-rawio.patch.bz2 since cdrecord would not
compile (I'm on a rhel3 system).
Couldn't use cdrtools-2.01a27-o_excl.patch.bz2 since the patch didn't apply
cleanly.
It will fail with (DVD-RW media, couldn't test DVD+RW media)

===== 5) linux issues
As usually, linux will sometime spit weird messages to the system log
without much details.
kernel: sr0: CDROM (ioctl) reports ILLEGAL REQUEST
This happened sometimes during dvd+rw-mediainfo (if run after cdrecord
-eject, cdrecord -atip), sometimes during other cdrecord commands.
To make user happy linux won't tell you what the problem/ioctl actually is,
however adding debug it seems to me the ioctl is always "Read TOC" so I
edited drivers/scsi/sr_ioctl.c changed
if (!quiet)
printk(KERN_ERR "sr%d: CDROM (ioctl) reports ILLEGAL "
into
if (!quiet && sr_cmd[0] != 0x43)
printk(KERN_ERR "sr%d: CDROM (ioctl) reports ILLEGAL "
If you know "Read TOC" is really important please tell me.
Thanks
