Very Computer

Hello,
Recently I installed LM 8.2 om my dual-boot PC which has TWO IDE cdrom
drives:
1. One CDROM (Asus X40) connected to /dev/hdd.
2. One CDR (LG) connected to /dev/hdb.

Both drives work (under Windows) and are recognized by the BIOS during
boot.
LM 8.2 created TWO CDROM icons on my desktop.
Yet, I can not access (read/eject) the ASUS (read-only) from Linux.

Please advise !

Following are the contents of my fstab file and the result from (a)
cdrecord -scanbus and (b) ls -l /dev/cdr*.

Thanks a lot !

Try the following, and try accessing the drive after each:
1) Add your username to the 'cdrom' group.
2) Create a new icon pointing to the correct device and mount point.
3) Try mounting it manually with 'mount -t iso9660 /dev/hdd /mnt/cdrom2'

The drive that is setup as a scsi device (see lilo.conf) is detected via cdrecord

Shouldn't the two line above read something like /dev/cdrom /mnt/cdrom .......
and /dev/cdrom2 /mnt/cdrom2 ......
where /dev/cdrom* are symlinks to the actual devices.

Well as regards my trials with CD-Rom issues- you may find the
following Mandrake reference useful:

http://www.mandrakeuser.org/docs/troubles/tqhvit1.html#sm

The article states that the first two parameters (/mnt/cdrom?) MUST be
present and identical for "supermount" to properly function. At least
that's my reading....

Also, you may want to read carefully this other Mandrake "errata" note:

http://www.mandrakeuser.org/docs/troubles/tqhvit3.html#cd

After reading, you may wish to do a "ls -l /dev/cdrom" and see where it
REALLY is linking to... I has a surprise you may too....

For some continual enjoyment you can read the thread "Re: floppy disk
and cd rom mounting problems" for a whole litany of on-going
"discoveries" regarding the supposedly AOK state the Mandrake
setup-scripts left my system in...

That's how things are done *normally*, but the OP is using Mandrake.
For some bizarre reason, Mandrake's recent distros use the
not-ready-for-prime-time devfs, and instead of using the tried-and-true
"mount", they use "supermount".  mount and supermount do the same
things, but the syntax is totally different for supermount.  devfs adds
another layer of complexity, since the old device names like /dev/hdd
are not there; instead, you have /dev/ide/host0/bus1/target1 .

This plays hell with newbies because then they try to get advice, and
all the old farts have no idea what is going on since no other distro
uses these things by default.
