Image sizes too big for SD card?

[MrWizerd]

I have 3 64 Gb Samsung Evo+ cards, all three are exactly the same size, when I try to use win32diskimager all three have gone through the test for speed and sectors and all three check out perfectly, no loss of data no corruption and speeds better than advertised. When I use diskimager it tells me that all three are around 900,000 bytes off... or bits.... Anyway the point is there all exactly the same size short. I have tried to remove there partitions, format them with different formatting tools, nothing seems to work. It also does it with my faster Samsung Extreame U3 32gb is also too small, though I don't remember by how much, for the 32gb image of course. When I use a unix machine to DD the cards, while it takes a VERY long time, they do write without issues, but I have never been able to confirm the cards work, as I was burning the touchscreen version and was having nothing but problems with it. I finally got it to go once but then restored a backup of something that bricked it, and gave up on the cards I had and bought another and was able to get it to come up on the first try after phoenix. Though phoenix took about 15 times to burn it correctly. But I have burned Ubuntu and Android HDMI over and over without problems booting. The only image I have had issue with is the Touch Screen one.
