gene@coyote:~/rock64.imgs$ /sbin/gdisk -l rock-img-shrunk.img
GPT fdisk (gdisk) version 0.8.5
Warning! Disk size is smaller than the main header indicates! Loading
secondary header from the last sector of the disk! You should use 'v' to
verify disk integrity, and perhaps options on the experts' menu to repair
the disk.
Caution: invalid backup GPT header, but valid main header; regenerating
backup header from main header.
Warning! Error 25 reading partition table for CRC check!
Warning! One or more CRCs don't match. You should repair the disk!
Partition table scan:
MBR: protective
BSD: not present
APM: not present
GPT: damaged
****************************************************************************
Caution: Found protective or hybrid MBR and corrupt GPT. Using GPT, but
disk
verification and recovery are STRONGLY recommended.

Humm, atf? Decode plz. This is (presumably) a u-boot machine, no grub
stuff to be found.
Thanks.
