I found the fix that worked. It is at the following link: http://forums.sandisk.com/t5/All-SanDisk-USB-Flash-Drives/i-might-have-destroyed-my-4gb-flash-drive/td-p/235732
Here is what I learned.
Right click computer >manage>storage>disk management
You should see the drive with unallocated space.
Right click the space, select “new volume”
Run through the wizard but do *not* format at this step.
When a new volume is created, it will ask if you want to format.
Format at this time.
Too bad the drive has to be formatted and all data lost. But at least I didn’t have to chuck it in the garbage.
