parted at a last resort. parted is a disk partitioner and will wipe

looking for sda*, that's the internal disk
sda1 -> EFI
sda2 -> Recovery
sda3 -> OSBoot
sda4 -> Media
EFI is fat32 and should be empty
Recovery is hfsplus and should contain the recovery partition bits
OSBoot is hfsplus journaled, this is AppleTV OS
Media is hfsplus journaled where r/w and media contents live
atv-booloader does not know how to mount fat32, a patchstick created
by atvusb-creator does know about fat32 (newer version of
use parted to list the partitions. penbuntu also has gptsync for
sync'ing the MBR to the gpt partitions. only the first four GPT
partitions will be sync'ed. If recovery/osboot are popped, gptsync
will not help you.
The important thing is to check recovery and osboot partitions. I bet
they have been wiped. So possible you are looking at a complete
rebuild operation without having a good recovery contents. see

not make a backup
