The superblock is the record describing the characteristics of the file
system, and it's bad if the filesystem routines concerned can't make any
sense of it.  For a dos fs, the information is in the partition boot
record.  If it tries to read number of fats and fat size from the MBR,
which it will try to do if you tell it to mount /dev/sda, that would
look like a bad superblock.  I wonder if fdisk /dev/sda can make any
sense of it.  It should, I think, see 1 partition, sda4.  Do you have
data on it you need, or can you risk recreating the mbr to see if that
helps?

Maybe the Iomega disk has come too close to a strong magnet at some
point?
