Sony DVD writer undetected on slack 10.2

Hi, i have a Sony DVD writer which is detected during startup, but how do i mount it, i mean do i have to change the /etc/fstab & /etc/mtab entries, is there a tool i should use to do this?

my dmesg shows:

Code:

hdc: DVD RW DRU-820A, ATAPI CD/DVD-ROM drive
hdd: SAMSUNG CD-ROM SC-152G, ATAPI CD/DVD-ROM drive

and my /etc/fstab is:

Code:

/dev/hda4        swap             swap        defaults         0   0
/dev/hda3        /                ext2        defaults         1   1
/dev/hda6        /fat-e           vfat        defaults         1   0
/dev/cdrom       /mnt/cdrom       auto        noauto,owner,ro  0   0
/dev/fd0         /mnt/floppy      auto        noauto,owner     0   0
devpts           /dev/pts         devpts      gid=5,mode=620   0   0
proc             /proc            proc        defaults         0   0

and /etc/mtab is:

Code:

/dev/hda3 / ext2 rw 0 0
proc /proc proc rw 0 0
/dev/hda6 /fat-e vfat rw 0 0
devpts /dev/pts devpts rw,gid=5,mode=620 0 0
usbfs /proc/bus/usb usbfs rw 0 0

I think you just have to add a line to fstab and create a mount point for it, such as /mnt/dvd.

/mnt/dvd already exists so just add a line to fstab the same as the entry for your cdrom, except with /dev/dvd and /mnt/dvd.

thanx for the reply,
i added this line in /etc/fstab:

Code:

/dev/dvd         /mnt/dvd         auto        noauto,owner,ro  0   0

but when i mount using:
# mount /mnt/dvd

i get this error:

Code:

mount: No medium found

and by the way, even though i couldn't mount the dvd, i am able to write dvd's from K3b

Have you rebooted after changing fstab?

sharathg786 · 10-31-2006, 11:00 PM

Yes I have rebooted and by the way, the cd-ROM is connected as slave & DVD-writer as master to the secondary IDE channel.

sharathg786 · 10-31-2006, 11:46 PM

Hey I did this and the problem was solved

, however i wanted to know if it is a safe way to do it:

I changed my /etc/fstab which earlier looked like:

Code:

/dev/dvd         /mnt/dvd         auto        noauto,owner,ro  0   0

to this:

Code:

/dev/hdc         /mnt/dvd         auto        noauto,owner,ro  0   0

and now i'm able to mount the DVD.

Assuming /dev/dvd and /mnt/dvd exist, it should have worked. Which kernel are you using? If it's 2.4, you need to put append="hdc=ide-scsi" in /etc/lilo.conf, and then re-run lilo. Using /dev/hdc should be fine though.

michaelk · 11-01-2006, 07:07 AM

/dev/dvd and /dev/cdrom are links to actual devices i.e. /dev/hdc. /dev/dvd might actually be linked to hdd not hdc. It doesn't matter what you use in the fstab i.e /dev/dvd or /dev/hdc as long as it is valid.
Check out
ls -l /dev/dvd
&
ls -l /dev/cdrom

BTW k3b does not use the fstab entry when burning.

sharathg786 · 11-01-2006, 08:35 PM

Yep, thanx for the suggestions, I'm using a 2.4 kernel & /dev/dvd is linked to /dev/hdd, will change it to /dev/hdc

Not automatically.

rm /dev/dvd
ln -s /dev/hdc /dev/dvd
