I reformatted the partition using mkfs.msdos -F32 /dev/sdb4.  The 
Properties display on both Windows and Linux identify it as F32 and VFAT.

The fstab entry is now

/dev/sdb4 /home/madolf/Common vfat 
noauto,uid=1000,gid=1000,auto,rw,owner 0 0

It shows up in /home/madolf as a disk volume icon on linux and \F on 
Windows.  All ownership is set to me not root.

PROBLEM: I can write and read on Windows. I can write and read on 
Linux.  BUT I cannot see on either system what was written on the 
other!  What's going on?
