[newbie] Please Help! Unable to mount Yamaha CRW4416E (read only!) in Mandrake 7.0
I just installed Mandrake 7.0 yesterday, but have been unable to mount my
Yamaha CRW4416E CRW drive! (I have no problems with NT or Win2K doing so!)
BTW, I am only trying to use the drive as a cdrom in Linux (so far!)
In my system I have an older 12x CDROM drive which mounts fine with the
"supermount" arguments given to it by the /etc/fstab file (I can access
it by single-clicking on the "Cd-Rom" desktop icon in KDE):
-
/dev/hda1 /c vfat user,exec,conv=auto 0 0
/dev/hda5 /d vfat user,exec,conv=auto 0 0

/mnt/cdrom2 /mnt/cdrom2 supermount fs=iso9660,dev=/dev/cdrom2 0 0
-
The permissions on the /dev "files" are as follows:
[tom@fiend tom]$ ls -lsa /dev/hdb /dev/hdc
0 brw--- 1 tom disk 3, 64 May 5 1998 /dev/hdb
0 brw--- 1 tom disk 22, 0 May 5 1998 /dev/hdc

0 lrwxrwxrwx 1 root root3 Jan 21 16:47 /dev/cdrom2 - hdc
-
When I try to access the Yamaha CRW4416E (by single-clicking on the
"Cd-Rom 2" icon on my desktop), an error box pops up that states:
KFM Error
Could not list directory contents
file"/mnt/cdrom2

A little more detail can be seen in the /var/log/messages file:

I don't think there is an issue with permissions, since I get the same
results when logged in as root. Strangely enough, I also had problems with
RedHat 6.1, spitting out the following message (when I had it installed) in
the /var/log/messages file:

Re: [newbie] Please Help! Unable to mount Yamaha CRW4416E (read only!) in Mandrake 7.0
I had a similar problem. First make sure you can mount the CD-RW manually. I
think the installer is smart enough to determine the drive is CD-RW, so it
sets up the SCSI emulation for you. It just doesn't change fstab to reflect
this. Try (assuming you want to mount it on /mnt/cdrom2):
mount -t iso9660 /dev/scd0 /mnt/cdrom2
You may have unmount /mnt/cdrom2 first. If this works, change the following
line (again assuming fstab is trying to mount your CD-RW on
/mnt/cdrom2/):
mnt/cdrom2 /mnt/cdrom2 supermount fs=iso9660,dev=/dev/cdrom2 0 0
to:
/mnt/cdrom2 /mnt/cdrom2 supermount fs=iso9660,dev=/dev/scd0 0 0
You are changing the "dev=" portion to point at "/dev/scd0".
Hope this helps.
