killall udiskie
Use a filesystem with CRC Checking.
sudo dd if=/dev/sdc of=DEVICE.IMAGE bs=64M iflag=dsync oflag=dsync
Make more then one image, then sha512sum the images to make sure you have the good data.
Mount Loop Image
- read/write
losetup --partscan --find --show disk.img
- read only
losetup --partscan --find --show --read-only disk.img
- mount
mount /dev/loop0p1 /media/temp
- remove loop device
losetup -d /dev/loop0
Save and Restore Partition Tables
pacman -Sv gptfdisk
- backup
sgdisk --backup=<file> <device>
- restore
sgdisk --load-backup=<file> <device>
- list
gdisk -l <device>
