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=00h�
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' /dev/cdrom: engaging DVD-RW DAO upon user request... :-[ 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) -- Turning BURN-Free on input buffer ready. trackno=0 BURN-Free is OFF. BURN-Free is OFF ... -- cdrecord: Turning BURN-Free on trackno=0 BURN-Free is ON. Turning BURN-Free off BURN-Free is OFF. ... -- BURN-Free is ON. Turning BURN-Free off BURN-Free is OFF. cdrecord: Turning BURN-Free on Performing OPC... ... -- prodvd will always just say "BURN-Free is ON." ==== 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) cdrecord -v -data -sao blank=fast gracetime=1 dev=1,0,0 speed=0 driveropts=burnfree test.iso ... cdrecord: Found DVD media: using cdr_mdvd.

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.
