It would be more proper if this was to denote the size as "GiB" so the end result can be determined whether or not it is really "Gib". "[X]i" in it self does not signify the size of the data by which the result was calculated but only that the result has been calculated by 1024^N and seems to have been a mislead representation by other OS's. So whether were using BLOCKSIZE of "b B K M G T P..." can we adjust this so it displays the increment correctly please ? http://en.wikipedia.org/wiki/Byte http://en.wikipedia.org/wiki/Megabyte http://en.wikipedia.org/wiki/Gigabyte [...] http://en.wikipedia.org/wiki/Template:Quantities_of_bits http://en.wikipedia.org/wiki/Orders_of_magnitude_%28data%29 --=20 Regards, J.
