Linux N00b cant get scsi cdrom mounted

Im a rank n00b in Linux. I have installed Ubuntu server 10.10 today and I am trying to mount the scsi cdrom drive in a Dell Poweredge 2850. I can see the device in dev listed as scd0, but when i try to mount it to /media/cdrom or /mnt/cdrom I get a long list of I/O errors:
Buffer I/O error on device sr0. Im absolutely certain its something I need to learn and Im hoping someone can point me in the right direction. TIA!

Ok progress. I wasnt using -t iso9660 -O ro .. now that I have that, Im getting the following:
"according to mtab /dev/sr0 is already mounted on /media/cdrom"

However if I go to /media/cdrom and ls, there is nothing there. I have a CD in the drive, and it has a .run file on it.

Normally a file whose name starts with a period will not show up using ls. You have to use the -a parameter to see them.
ls -a /media/cdrom
If you used a GUI file manager like Nautilus you would have to enable "View Hidden Files" to see that file.

I wanted to help you with your first post but you didn't put in enough information. Generally you should include the exact command that you are using and the exact error message, for example.

That was the problem. Using the -a switch shows me the file. I read teh man page for ls, but it never occurred to me that the file would be hidden. I donwloaded it from fileplanet and burned it to a CD. Also the file name doesn't start with a period, its actually named . Does that mean the file has the hidden attribute set in it? Thats odd.. Sorry for not including enough info in the first post. Now at least I know I dont have a problem with the CDROM not being correctly mounted.
