failure to blank CDRWs (2.2.18pre15 smp ide-scsi hp7100i)

Hi all,

Just to follow up on an earlier message / thread. I've updated to
2.2.18pre15 on the machine (dual celeron, gigabyte 6bxd) I was having
trouble writing CDRWs to, and it has made no difference,

With the same tools / os on my other cdrw equipped machine
(k7/up/ricoh 9060) the very same CDRW will blank perfectly happily.

Both machines have the CDRW as the sole device on the second

Using xcdrgtk's blank cd option which uses cdrecord 1.8.1 on the
failed machine gives the following log. Using speed=1 or spped=2
makes no difference to the error reported.
