and all should be as it was when you first used it.
Make sure it is formatted as OS X Extended (Journaled)
CAUTION: The ENTIRE contents of that drive will be erased when you initialize it.

I've been using it for quite a while now and it has operated flawlessly. But now i get the "the disk is full-backup failed" message. TM drive is 250G, my main drive has 117G used. So I decided to erase the TM drive and start from scratch. Now I get an error that says drive is 250G but 450G of space is required. I have no idea why it requires 3 times as much space as is on my main drive. I do also have a a disk image backup using "carbon copy"
How do i set it up as if it was the first time i used it?
