That was I, but it won't do you much good until you fix the
filesystem, which I can't be of much help with because I don't know
how it's broken.  Once you get it back the way it was (mountable and
readable but not writeable), see if you are able to write to it as
root.  If so, you can add an option to the mount command (or to
/etc/fstab) that will allow other users to write to it.

This suggests to me that you may have hosed the partition map on
/dev/sdb.  If so, you can use pdisk or parted to write a new one and
to create a partition where the old one used to be (if you know where
it was) without erasing the filesystem data it contains, but I'd
proceed extremely carefully and with the close supervision of somebody
familiar with the procedure, as a mistyped character can destroy your
whole universe.
