Is there a way to bypass disk restore limit

Question

Hi I had a image of my old 8GB pendrive and I wanted to make an additional copy on a new USB 3.1 pendrive. it is also 8gb so when I used the restore disk image it says the image is 23 mb bigger than the disk. how do I fix this!

Answer 1

Truncate image file

Removes unwanted space from end of image file so image fits on smaller drive when flashed

Input

ubuntu@ubuntu:~$ cd /media/ubuntu/DATA/
ubuntu@ubuntu:/media/ubuntu/DATA$ fdisk -l DiskImageofsdd.img
