The above makes no mention of anything on /dev/sdb.  So you haven't
mounted it, or it can't yet be mounted.

What steps have you gone through?

To make use of a drive, you partition it (even if that means using the
whole drive as one partition), fdisk is one tool that you can use.  A
quick glance at the above looks like you've done that okay.

Then you format it with a file system (e.g. man mkfs.ext3).

Then you mount it (e.g. man fstab &/or man mount).
