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):
---------------------------------------------------------------------

/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
[tom@fiend etc]$ ls -lsa /dev/cdrom*
0 lrwxrwxrwx 1 root root 3 Jan 21 16:47 /dev/cdrom -> hdb
0 lrwxrwxrwx 1 root root 8 Jan 21 21:51 /dev/cdrom1 -> /dev/hdc
0 lrwxrwxrwx 1 root root 3 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:

The difference between the two distributions is that with RedHat 6.1,
I was at least able to mount & use the drive, however I can't with Mandrake
7.0.
To top this all off, when I installed Mandrake 7.0 yesterday, I used this very
same Yamaha CRW4416E as the installation drive, so I know Mandrake is
capable of reading information from it properly!
If anyone can point me in the right direction, I would be very
appreciative.
Thanks,
Tom
