Mounting cdrs a bust

Interesting; the ATA: device naming spec doesn't always work properly IME. It's usually better-easier to give the normal device name, like "dev=-dev-hdc", even though Joerg complains about it.

All right, if it can successfully burn a CD-RW but not read one, there's something weird going on. How are you mounting it? Does a simple command like "dd if=-dev-hdc of=-dev-null bs=512 count=1" return some sort of read error? If dd works, it's something dumb happening within mount. Or a bad filesystem--I have a DVD here burned by a friend with an OS X app, and mount can't seem to determine the filesystem automatically; I have to manually specify -t iso9660 or it won't mount.

Devices that fit in an Ultrabay are a lot more expensive than standard 5.25" devices. So, the next thing to try is to upgrade the device's firmware (if possible). The firmware on IBM devices, while usually OK, can have many bugs. (A friend of mine admins AIX for a living, and has told me extensive stories of things like a SAN dropping all of its disks because of a firmware bug.) The firmware upgrade procedure may require Windows; hope you have that sitting around somewhere. HTH anyway,
