Hi. This is my first post and question in this forum. I am not a beginner by the way. I had CCNA in the past. Also, I use Debian GNU/Linux (Wheezy) since like 10 years at least. I say so for you , forum members, to make it easier for you to communicate with me and NOT to waste your time.

Whenever I restart/reboot the topology emulation, I see the disk0: unprepared, although before rebooting it was prepared and formatted. I always have to re-format the disk0: and start over. So, how I can keep the disk0: formatted there? I have disk0: in every router in the topology.
