OK, a belated follow-up to this... I upgraded to 2.6.10, and tried many combinations of dropping the suid bit and using dev=ATAPI:x,y,z, dev=ATA:x,y,z and dev=/dev/hdx. Nothing worked. I still got the same flood of errors and lockups. Though for some odd reason, cdrdao carried on working all through. Extensive googling revealed about three people who also had a CyberDrive CW-088D and they couldn't get it to work either (though apparently the CW-058D does work). A couple of days ago, the drive ceased to make good recordings - the burn process (using cdrdao) would complete normally, but reading the disk back produced input/output errors after an undefined but large number of sectors had been read. Reading the disk with a different drive produced the same result. I replaced it with a Philips PBDV1640B CD/DVD writer, and without any software upgrades cdrecord started working again (using dev=/dev/hdx and not suid). (Result for CDs; I haven't tried burning DVDs yet.) I have written http://pigeon.dyndns.org/stuff/cw088d.html in the hope that it will help others avoid finding out the hard way that the CW-088D is buggy. -- Pigeon Be kind to pigeons Get my GPG key here: http://pgp.mit.edu:11371/pks/lookup?op=get&search=0x21C61F7F
