I also will add that the 'umask' option is taken from the current
environment.  If your .bash_profile already has a line of 'umask 022',
then you really don't need it in the mount command line.  I also think
that 'rw' is a default, so you really don't need that either:

mount -t vfat -o uid=bob,gid=bob /dev/hdd1 /scratch

'should' work.  You just can't change permissions on individual files.
Note that if you copy /scratch/foobar to your ext3 partition, it will
keep the same file permissions as how you mounted /dev/hdd1.  So in this
case if you copy over /scratch/foobar to /home/bob, the file
/home/bob/foobar will be chmod 755.  You can work around this by setting
the umask, dmask, and fmask options on a vfat filesystem.  dmask for
directory, and fmask for ordinary files:

mount -t vfat -o uid=bob,gid=bob,dmask=755,fmask=644 /dev/hdd1 /scratch

More that you needed to know about mount. =)
