It also seems to be mounted by the hot plug manager (it is set up as 'managed' as you can see by the options). Did you just recently install it? If there are no problems try using fdisk to check/change the partitons to what you want (ext3 I assume) and format the filesystem, then change the line in fstab to reflect it properly and it should work.
