Also, incidentally, looking at the directory structure in Windows,
I've got a bunch of corrupted data on the drive. As Linux will not
let me do anything to the drive (nor does it show this data), and
Windows will not let me delete those files due to the names they're
showing up as (invalid syntax), I'm going to end up having to format
my drive it looks like.

Any suggestions as to how I can avoid this in the future? Because I'm
going to need to copy data back over it to get everything set back up,
and I'd rather not see it get corrupted like this again.
