Mounting multiple CD's

From ali on Mon, 14 Dec 1998

HI

I've just recently purchased a copy of Red Hat Linux 5.0 and a new CD drive(ie. I now have 2 CD drives) and I need to know how to mount them.

The 2 drives are connected to the IDE on my soundblaster AWE-64 sound card and I need to know how to mount the drives from there. (I previously had one drive and mounted it using /dev/cdrom but now what do I use?)

/dev/cdrom is normally a symbolic link (sometimes a hard link) to some other device node such as /dev/hdc (first device on the second IDE channel) or /dev/scd0 (first CD device on the first SCSI channel).

The two drives are:
1) Samsung SCR-2030
2) HP CD-Writer Plus 8100

These (and the fact that you refer to your Sound card) sound like SCSI devices. You'd simply find out which of these your /dev/cdrom is linked to (by mounting it as normal or inspecting the 'ls -il' output of your /dev/ directory).

[ And, you could tell which one it was since its light will flash when you mount the disc. -- Heather ]

For the other you'd use a command like:

mount -t iso9660 -o ro /dev/scd1 /mnt/cdrom1

... where the -t specifies the filesystem type (ISO 9660 is the standard for normal CD's), -o is a set of options (read-only in this case) and the next two parameters are a device name (second SCSI CD drive), and an arbitrary mount point (usually an empty directory under the /mnt tree --- or an empty directory in any other convenient location).

You could name that mountpoint anything that your filesystem will allow (just about anything). I use /mnt/cd* or /mnt/cdrom* as prefixes to these names for obvious reasons.

If this new drive is on an IDE interface its likely that you'd use something like /dev/hdc or /dev/hdd for the device name.

Any help will be appreciated.

Thanks Ali
