	If you inserted an USB disk drive in addition to your Terastation array, it will probably be automounted under ''/media'' folder under the disk's name. My Lacie 320G USB disk was mounted as LACIE. The commands above assume you want to mount the system in read only mode (does someone want to comment on the parameters? I mounted mine without any but I'm not 100% sure I should've done that. My array is now fine, though.) I also assume the disk you're backing the files up to contains enough space for your Terastation files. I only had 40GB of data there so I was ok.
