I had an interesting problem while backing up some files to an external
hard drive.
I'm a teacher, so I create a folder for each class and put all handouts,
student work, etc., in these folders. Since I'm supposed to keep
everything for a year, I move the folders to an external hard drive at
the end of the semester. Doing this keeps them out of my hair until I
can delete them altogether.
Anyway, I didn't get around to moving my folders until today. When I
did, a couple of student papers were not moved. I got a dialog saying
they couldn't be copied because my hard drive doesn't support
encryption. I do remember opening and reading the files without any
problem. In fact, when I can't open a file, I ask the student to
resubmit it, and I delete the bad file right away.
So my questions are these:
* Why would the hard drive say files were encrypted when I can open them?
* Why would encryption matter to a hard drive? Presumably I might want
to back up my top secret files as well.
Just curious.
