How to remove or change HD partition icon or name on unity file brows page?

[vichy]

hi All:
I use ubuntu 14.04 LTS  and use red rectangle partitions I show in
attach pics for back up my data.
But I will sometimes open backup directories instead of current
directories for file editing, since 2 partitions looks up the same

1. is there any method I can turn off ubuntu automatically show those
directories when I open unity file brows, like not show red rectangle
partitions in attach pic?
2. Could I change the name of those partitions as some special one
that I will mess up?(right now it show "400GB Volume" and I want to
change it as "BACKUP1", etc.)

appreciate your help,
