Steve,
Are you sure the your kernel supports iso9660? Check that /proc/fs ( /proc/filesystems ) shows iso9660 in your kernel. After that I'd reset the system ( reboot ) to make sure that one of the drivers hasn't gone out to lunch. ( Or you could do the rmmod/insmod thing ). Did you setup the kernel parameter for ide-scsi or did a script set it up?
I haven't had this much trouble in the past with mounting drives. Did you build the kernel yourself?

Bill,
I checked out /proc/filesystems and iso9660 is supported. I was able to mount a CD in my DVD drive and look at it with no problems. I setup the kernel parameter for ide-scsi. I was following the instructions located at http://www.troubleshooters.com/linux/cdrw.htm. I built the kernel (2.4.23) myself. I rebooted but it made no difference.

Tim,
I tried the other devices you listed but got the same error. Since I rebooted, I decided to go into Windows (ugh) which read the CD-RW just fine.
After rebooting back into Linux I decided to take a look at dmesg in case anything stuck out. Included are the bits dealing with the CD-RW drive.
hdd: Hewlett-Packard CD-Writer Plus 9300, ATAPI CD/DVD-ROM drive hdd: attached ide-scsi driver. SCSI subsystem driver Revision: 1.00 scsi0 : SCSI host adapter emulation for IDE ATAPI devices Vendor: HP Model: CD-Writer+ 9300 Rev: 1.0c Type: CD-ROM ANSI SCSI revision: 02 ide-scsi: hdd: unsupported command in request queue (0) end_request: I/O error, dev 16:40 (hdd), sector 64 isofs_read_super: bread failed, dev=16:40, iso_blknum=16, block=32
These last three lines stick out at me. I'm guessing the error at ide-scsi might be causing the other two and thus the mounting problems, but have no idea what command it's bitching about.
Finally, since you might ask, here is the lilo entry:
image=/vmlinuz
label=Linux
read-only
append="hdd=ide-scsi"Thanks, Steve
