Earlier this year, I bought two identical USB drives for my repair tools. I spent a lot of time making the repair tools USB drive just the way I needed, so I rightly wanted a backup. USB drives always fail, and when you use one as much as I do, they fail quickly. This was, of course, the reason why I bought two identical USB drives. I decided to use Clonezilla to make the backup. I have had a lot of success copying drives with Clonezilla.
Today I tried to recover my backup using Clonezilla. I spent one hour trying. No matter what options I chose, what I did, it would not succeed. The error message it gave me corresponded to a disk too small, but how could an identical drive of an identical size be smaller than the original? Anyway, lesson learned. Now I will have to spend a lot of time re-creating my USB drive. This time, I am going to use a different backup program.
