Hi, ehmm, am I the only one who sees this problem (since end November): I cannot mount, let alone burn, rewriteable CDs on -stable boxes (two) with adaptec SCSI-controller (one 1542, the other 2940) and SCSI-2 cd-writers. Recordable CDs read and write without any problem, changes settings in the Adaptec BIOS do not seem to make any difference. step 1, put (Windows created) CDRW in cd-writer: su-2.05a# mount_cd9660 -v /dev/cd1c /cdrom could not determine starting sector, using very first session mount_cd9660: /dev/cd1c: Device not configured step 2, put very same CDRW in cd-reader on very same machine: su-2.05a# mount_cd9660 -v /dev/cd0c /cdrom using starting sector 0 su-2.05a# ls /cdrom cd su-2.05a# step 3, put a CDR in cdwriter: su-2.05a# mount_cd9660 -v /dev/cd1c /cdw=20=20 using starting sector 0 su-2.05a# ls -l /cdw total 1 -r-xr-xr-x 1 root wheel 3728 May 1 1997 readme.txt If this helps, this is the output when trying to blank a CDRW: su-2.05a# cdrecord -v dev=3D6,0 speed=3D1 blank=3Dfast Cdrecord 1.10 (i386-unknown-freebsd4.5) Copyright (C) 1995-2001 J=F6rg Sc= hilling TOC Type: 1 =3D CD-ROM scsidev: '6,0' scsibus: 0 target: 6 lun: 0 Using libscg version 'schily-0.5' atapi: 0 Device type : Removable CD-ROM Version : 2 Response Format: 2 Capabilities : RELADR SYNC LINKED=20 Vendor_info : 'TEAC ' Identifikation : 'CD-R55S ' Revision : '1.0F' Device seems to be: Teac CD-R50S.

The other machine wich exhibits this behaviour, has a YAMAHA CRW4416S 1.0f = cdwriter (and both of them work correctly for CDRWs until end November). Any help, suggestions are appreciated. One of the machines is a production = box, but the other is halted almost every evening and I can easily test a patched ke= rnel. Thanx in advance, Arno Klaassen --=20 Arno J. Klaassen SCITO S.A.
