Hi Markus, thanks for your information on cd and dvd drive.
I am a Linux and Knoppix newbee, trying to read write DVD-RAM media with udf.


Knoppix is 4.0.2 Kernel is 2.6.12 which is installed in hard disk /dev/sdb1.

DVD-RAM drive is ATAPI HL-DT-ST GSA-4163B

dmesg | grep 'DVD' displays:
hda: HL-DT-ST DVDRAM GSA-4163B, ATAPI CD/DVD-ROM drive

I think I followed your method to enable this DVD-RAM drive.

ll /dev/dvd displays:

lrwxrwxrwx 1 root root 8 2006-04-14 07:33 /dev/dvd -> /dev/hda



If needed do
root@mrk-fujibox:/# mkdir /cdrom /dvd
root@mrk-fujibox:/# chgrp cdrom /cdrom /dvd
root@mrk-fujibox:/# chmod 770 /cdrom /dvd
In this part, shall I do
chgrp cdrom /dvd
chmod 770 /dvd
?

fstab is edited as follows:

And I tried to mount DVD,
mount -t udf /dev/hda /mnt/dvd

mount: /devhda is not normal block device

How do I mount the DVD-RAM drive ?

BTW mount displays:
/dev/root on / type ext2 (rw)
/ramdisk on /ramdisk type tmpfs (rw,size=1643952k)
/UNIONFS on /UNIONFS type unionfs (rw,dirs=/ramdisk=rw:/KNOPPIX=ro,delete=whiteout)
/dev/sdb1 on /cdrom type ntfs (ro,uid=1000,gid=1000,fmask=0177,dmask=077,nls=euc-jp,errors=continue,mft_zone_multiplier=1)
/dev/cloop on /KNOPPIX type iso9660 (ro)
/UNIONFS/dev/pts on /UNIONFS/dev/pts type devpts (rw)
/proc/bus/usb on /proc/bus/usb type usbfs (rw,devmode=0666)
automount(pid2876) on /mnt/auto type autofs (rw,fd=4,pgrp=2876,minproto=2,maxproto=4)
/UNIONFS/dev/sda7 on /mnt/common type vfat (rw)

hard disk sdb1 where the Knoppix image is located, is mounted on /cdrom

Thanks in advance.
