You have destroyed the prior filesystem, but you've never actually
created a new filesystem.  'mount' expects to find a filesystem. 
Sadly enough, a fat32 filesystem is not a bunch of zero'd sectors.

Many Linuxes have a mkfs for "DOS" filesystems, so if you wanted to
create a fat32 filesystem, try running:

/sbin/mkdosfs -F 32 /dev/sda1

(The -F 32 makes it create a "FAT 32" filesystem, instead of 12 or 16
or whatever the default may be)
