One thing that I see that is strange is the partition table on the
second drive. It says you have a 1 TB Win95 FAT32 partition. I
didn't think you could make them that big. What I would try is to
use parted or gparted to delete the partition table and create new
partitions that reflect how you are planning to use the drive. MAKE
SURE you change the drive to /dev/sdb before deleting the partition
table. Also, if you have any data you want on the second drive, back
it up before doing anything.

If you can, use gparted instead of parted. Parted is a command line
utility and can be harder to use.

One you have partitioned and formated the drive, you will have to
add it to /etc/fstab if you want it mounted automatically. (I forget
the GUI tool that does that - I just edit it by hand...)

You may be able to mount the partition on /dev/sdb1 if you really
want to. Use something like this to see if it has a valid file
system on it. As root, or using sudo, run:

mkdir /tmp/mnt
mount /dev/sdb1 /tmp/mnt

If it mounts, you have a valid file system on the drive. If the
system can't determine the file system, then it probably isn't
formatted.

Have fun.
