I have six hard drives in my system - four internal, and two external that are only powered up occasionally for backups.

My F:> drive is a two-terabyte internal drive that is backed up to my identical external L:> drive. F:> is somehow listed as a system drive. It is entirely data, containing nothing but a few audio books. (Few = 3877 books, 1769 gigabytes. )

Because it is shown as a system drive, it seems to be using up 29GB more space than the L:> drive, and when I run backups it throws errors trying to back up a very few files that apparently are involved in this "system" business. Not a great problem, just annoying.

What do I need to do to convince the computer that the F:> drive is not a system drive?
