    Hi, I recently upgraded most of the hardware on my system, but pulled
    out the cdrom and installed it in the new box. Now I am not able to
    mount it successfully. This is a normal ATAPI IDE cdrom drive, and I'm
    running testing. The kernel is 2.6.10 and of course has the atapi
    driver compiled in.

    /dev/hdc is the cdrom device. This is what happens when I try to mount
    it: 

    ---
jashenki:~# mount -t iso9660 -r /dev/hdc /mnt/cdrom
mount: wrong fs type, bad option, bad superblock on /dev/hdc,
       missing codepage or other error
       In some cases useful info is found in syslog - try
       dmesg | tail  or so
---
The output of dmesg seems to indicate that everything is fine, up until 
I try to mount it.  Here is the related output:
---

...
hdc: ATAPI 50X CD-ROM drive, 128kB Cache, UDMA(33)

---
And then when I attempt the mount this message shows up in dmesg's tail:
---
hdc: command error: status=0x51 { DriveReady SeekComplete Error }
hdc: command error: error=0x54
ide: failed opcode was 100
end_request: I/O error, dev hdc, sector 64
isofs_fill_super: bread failed, dev=hdc, iso_blknum=16, block=16
---
The drive's jumper is set to "cable select".  I originally had it set to 
master, and changed it to see if it would fix the problem.
Any ideas?  Thanks in advance.
