DD clone boots but files are missing and with wrong permissions, why?
Hi,
I've got Armbian Jessie setup as I want and wanted to clone it for backup. But when I boot the clone I get errors that lightdm can not start and my home dir is owned by root and is empty. The sudoers file is missing etc etc. Any ideas why this is happening? I've cloned Raspberry images hundreds of times and never seen this. The original card still boots perfectly?
I've used this line to clone (on a Ubuntu machine)
sudo dd if=/dev/sdc of=~/sdclone.img
and when writing back
sudo
Always do a verify since otherwise you never know when your hardware and/or dd failed. The following might require an
apt-get install gddrescue p7zip
first. And then given we're talking about an SD card available as /dev/sda it's just:
root@ubuntu:~# cat /proc/partitions
major minor #blocks name
179 0 3887104 mmcblk0
179 1 3686400 mmcblk0p1
8 0 500224 sda
8 1 1024 sda1
root@ubuntu:~# md5sum /dev/sda
