Charles:  Let's see what we have here.  Maybe a little more information will
help to fix the problem.

What kind/size of USB disk are you using?  I have a 120GB Maxtor drive and a
160GB Iomega HDD disk and both are happy.

Is the disk connected to the computer when the system boots?  If so the
output of 'dmesg' should show you what device file belongs to the disk. 

Were you able to determine the device file name, like '/dev/sda1' or
'/dev/sdb2', that it is using?

When you say that the disk is formatted as vfat, does this mean that you
executed the mkfs command?  You would have done something like

mkfs -t vfat /dev/sda1

to do this. 

I had a problem with the virgin format on my Iomega disk from the factory.
Although the partitions were acceptable to Windows, parted reported that
partitions were overlapped and the disk was not usable on Linux.  I had
similar results to yours:  the disk would spin up, run for a bit, and then
shut down.  After using mkfs, I was able to use the disk (I used ext3
instead of vfat to get support for large files).  But out of the box, it did
not work.  The Maxtor disk had no issues once I discovered the proper device
file name.

Perhaps this will give you some ideas that will help you solve the problem.
Remember that running mkfs will take a long time on a large disk (mine took
about an hour), and WILL DESTROY DATA on the disk.
