i am using openhabian option 54 to take raw copy of my internal card.If my system is running and i insert the usb card reader with exactly same sd card as my internal one and start option 54 i get :
Taking a raw partition copy, be prepared this may take long such as 20-30 minutes for a 16 GB SD card FAILED (set random UUID) mount: /storage/syncmount: wrong fs type, bad option, bad superblock on /dev/sda2, missing codepage or helper program, or other error. sed: can't read /storage/syncmount/etc/fstab: No such file or directory umount: /storage/syncmount: not mounted. OK (dirty bit on fsck /dev/sda2 is normal)
if i do a sudo reboot ,after reboot the copy with option 54 work ok :
Taking a raw partition copy, be prepared this may take long such as 20-30 minutes for a 16 GB SD card OK
what seems to be the problem?
