Hi,
so I had this problem with my Seagate GoFlex Home device getting bricked after pacman update:

It bricked again and I have no idea how to restore it. I unpacked the whole structure on the disk, but I cannot see the disk get it's DHCP address - it runs with self-generated IP and (169.254.x.x) and sends ARP requests looking the 10.0.0.x addresses, similar to these ones:

I got lost and could use some guidance. What would be your next shot ?
