No, you make a file system for a CDROM with mkisofs, then you write the resulting data to the disk in one shot. > mutsgo# cdrecord -dummy -data -speed=6 dev=0,3,0 /dev/rwdc0c > cdrecord: No such file or directory. No read access for '/dev/rwdc0c'. Sorry, typo. /dev/rwdc0c should of course be /dev/rwcd0c. > mutsgo# cdrecord -dummy -data -speed=6 dev=0,3,0 /dev/rwcd0c > Cdrecord release 1.8a22 Copyright (C) 1995-1999 Jörg Schilling > cdrecord: No such file or directory.

Reading my raw IDE CDROM, /dev/rwcd0c, gives me an error after about 150 MB... Lemme see... Using device /dev/wcd0c gives the same result... I wonder if... OK, it looks like the error I get is the result of getting to the end of the CD. It looks like the whole CD is copied, # cp /dev/wcd0c /var/tmp/cdimage cp: /dev/wcd0c: Input/output error # mount -t cd9660 /dev/wcd0c /cdrom # vnconfig /dev/vn0c /var/tmp/cdimage # mount -t cd9660 /dev/vn0c /mnt # diff -r /cdrom /mnt # ls -l /var/tmp/cdimage -rw-r----- 1 root bin 152764416 Aug 12 00:39 /var/tmp/cdimage # df -k /mnt /cdrom Filesystem 1K-blocks Used Avail Capacity Mounted on /dev/wcd0c 148928 148928 0 100% /cdrom /dev/vn0c 148928 148928 0 100% /mnt That is, they are exactly the same. Check in the above example if your source CD is not about 8761344 bytes. If the fact that the read is finishing on an error causes trouble, you can do like I did above and copy the CD image directly to a file on the HDD first. HTH. -- Crist J.
