[CentOS] Flash Drive problem?

[Ron Blizzard]

I've been having an odd problem lately. When I drag files from the
computer to a flash drive, they appear to copy, but when I try to use
the files I find that only the name was copied (file size of 0). When
I copy the same files to the same flash drive, from the terminal,
everything seems to work.

Has anyone else experienced a problem like this? It's starting to get
a little frustrating.
