Joybell -

You cross posted while I was pretending to be thinking really hard.

If you've figured out how to get the extra drives off, then by all means try that out.

The caution against showing System files is because if you can see them you might be tempted to change them. Making them visible won't affect how they run. Just don't delete them without being pretty sure of what you're trying to accomplish.

Once you've checked out what's there - or isn't - you can of course put the check mark back if it makes them emote more intimately with the rest of your machine. One likely shouldn't operate a machine routinely with a naked system, especially one that blushes easily.
