It was my USB drive, and here is my final post on the problem. I wrote:

The reformat worked. Looks like the USB drive became corrupted...again!
Before I reformatted the drive I copied all the files into a temporary
"Niels USB Drive", on my desktop.
Since the drive was corrupted, the drag and drop would freeze, soI had to
one sub-directory at a time. The drag and drops still froze, and the copy
boxes never closed, so I had to check that the files were indeed copied
to the temporary directory and could be opened.
I had to log out a couple of times to clear the copy messages, and then
copying directories to the temporary directory.
Once the files were copied, I used fdisk -l to determine the drive name
Then used the Gnome Partition Editor, Gparted (previously installed), to
and format the USB drive as FAT32. The USB drive needs to be readable by a
Windows XP machine, so FAT32 is mandatory.
Gparted is scary, because it is possible to inadvertently format the hard
instead of the USB drive (I have not, and never intend to confirm this
I like my drives to have names so after the drive had been formatted I used
label the drive:
$ sudo mlabel -i /dev/sdc1 ::Niels
The new label doesn't show up, so I unmounted and re-mounted the drive to
confirm that ubuntu could see the new label.
Lastly I copied the files back.
