So I put a SATA drive in my new TP2. Mounted fine on disk1part1. I unmounted it, then formatted it EXT3. Mounted, now it's on disk2part1 and disk1part1 goes nowhere.

Is there any way to either move the drive back to disk1part1, or remove disk1part1 from /media? Or I can even plug a USB drive into the plug and have that mount on disk1part1?

Basically I don't want a hanging chad here. It's 100% in my head and completely not important, I'm just wondering if I can do anything about it.

From web interface admin section you can:
Unmount it, clear the db cache (it's a button next to format), mount again - these usually fix it.
Or
Unmount it, put "/media/disk1part1" in the text box next to the drive, and hit the Mount button.
