It appears I mounted the partition successfully (no error message when executing "mount /dev/sdc1 /mnt/skippy"), but when I change to the mount point directory ("cd /mnt/skippy") to get a listing ("ls -la") I get the following error:
ls: reading directory .: Input/output error
this is weird because I was able to mount and get a listing with my other drive successfully without error using the same steps.
any ideas why I'm getting an error with the first drive?
