could be that during the clone process, not all the blank space is actually cloned and transferred which would result in the different size.
Perhaps there is also an element of compression being applied here.
i asked this question recently but didn't get an answer. it's not a big problem or anything, i'm just curious. when i clone my mac book pro (snow leopard os) hard drive using SUPER DUPER, the cloned external drive doesn't match the mac hd in gigabytes. my mac hd is max 250 gigabytes, my external drive clone is max 320. however the mac hd reads as 233.71 gb used, and the cloned ext. drive reads as 216.54 gb copied.
shouldn't a cloned drive be exactly the same size as the original drive (mac hd) that's being cloned?
seems funny to me. thanks in advance,
