Need to start back to "0". What do I need to do?

Completely botched everything. Help!

I bought the My Book 8TB.

Hi,

You need to tell us something specific.

I cannot figure how to partition the My Book. I can see the My Book in Disk Management. One partition (3gb) for a laptop (Windows 10), a second (3gb) for a computer (Windows 7), and the other 2gb for an android phone if that’s possible. I have a My Book that’s 8 years old, but I have a feeling the HD in it is shot.

I did reformat the My Book for NTFS.
