Yes, relying on "all" 4GB eMMC's to be 100% the same size is not a good "backup/flash" design. This is why the official images use rsync and not dd.. Here are 3 of the eMMC's used for bbb's.. #Micron 3744MB: 3925868544 bytes -> 3925.86 Megabyte #Kingston 3688MB: 3867148288 bytes -> 3867.15 Megabyte #Kingston 3648MB: 3825205248 bytes -> 3825.21 Megabyte All "sold" ad 4GB models.. When crafting a *.img i usually assume "80%" of advertised space to play it safe..
