How do I erase Time Capsule that is not connected
I have a 2 GB Time Capsule that was previously used on another system so it's full of stuff from that system.
I have not connected it to my current Macbook Air 13 (2013) and my current wireless is provided by Cox Cable rental modem and router.
I want to securely erase the HD on the Time Capsule to prepare for sale, but cannot figure out how to do this.
Can someone give me a clue?
Must I re-setup the Time Capsule with my new system just to erase it?
Does anyone know if the Time Capsule and Motorola (6121 I think) will work with Cox Cable in case I want to keep it?
Thx
