You might want to check on the health of your hard drive. A failing HD
will lead to all kinds copy failures.

Anyway: is there any way that you can verify if a jpeg file is working
correctly
/ not corrupt? Is there a way to verify that your "copy" operation was
successful?
(I have no evidence that the copy operation is what corrupted my files, so
maybe I should just continue on with my copy operations and trust that
they
are okay).
Your thoughts on this are appreciated!
it depends on what you're using to copy the files. Any decent backup
software will give you the option of doing a read-after-write check, which
means the software reads each block back after it has written it, comparing
them to make sure the write was successful. It should also give a choice
about what to do if the raw check fails - e.g. retry, continue, ignore - and
send you a message about it, on the screen, in an email or maybe a series of
cryptic beeps.
You should check your copy operation thoroughly before you decide to just
continue with it.
I run xcopy as a scheduled task rather than backup or some other specialised
software because it's simple and puts an exact copy on the backup drive
rather than some humungous file in a non-obvious format, and is easy to
restore.
