Can't Copy to Half-Full Thumb Drive—Why?

Under the category of the more things change, the more they stay the same.....

From my dad: *Murphy's Laws on Computers*

• As soon as you delete a worthless file, you'll need it.
• Installing a new program will always mess up at least one old one.
• You can't win them all, but you sure can lose them all.
• The likelihood of a hard disk crash is in direct proportion to the value of the material that hasn't been backed up.
• There are only two kinds of computer users: Those whose hard disks have crashed, and those whose hard disks haven't crashed yet.
• Anything can be made to work if you fiddle with it. If you fiddle with something long enough, you'll break it.
