Reading CD Discs on an IDE CDR Drive

From balou nguyen on Wed, 14 Jul 1999

I recompiled my kernal 2.2.9-19 to use my cd-writer as per the cd-writer howto. I had to enable scsi-emulation in the block devices, and enable scsi support for cdrom in the scsi. Now xcdroast works great, but I can't mount my cd, and I can't use cdplayer.

I can still play the cd if I go through xcdroast though.

Commands I have tried include:

mount -t iso9660 /dev/sg0 /mnt/cdrom

I would never expect that to work. The sg driver is for "generic access" to a SCSI device. It doesn't provide the semantics for block read/write (like a hard disk or other filesystem driver)

insmod ide-cd
mount -t iso9660 /dev/cdrom /mnt/cdrom

What are the major and minor numbers and type of the device node to which your /dev/cdrom points? If /dev/cdrom is not a symlink, make it so.

or

mount -t iso9660 /dev/hdc /mnt/cdrom

Is this drive the master on the secondary IDE channel? If not, than this is your problem. Try /dev/hdb (slave on primary channel) or /dev/hdd (slave on secondary channel).

I've also tried the other various recommendations in the howto without success...

You may have me stumped. I haven't purchased an IDE CDR or CDRW yet. So I don't have first hand experience with this. (I've been meaning to get a CDRW or a DVD RAM drive soon. Maybe I'll know better in a month or so).
