I have three external hard drives, 2 x 750GB USB3 Western Digital, and 1 x 1TB Western Digital Caviar Black spinner.
All three have identical data on them, right down to the last byte ... both for the size of data itself; and the size of data on disk.
This is true whether they are opened on W8 or Windows 7 machine. Yet when I open all three of them simultaneously on the machine that had W8, but now has Windows 8.1 ... while they all show the size of data, the size of data on disk is different for each one! Despite the fact that all three still show identical data on disk on Windows 7. Or even on Windows 8 if I reinstall it on the machine which 8.1 is installed on.
Can anyone explain to me why this is so? It is important because having the data on disk the same confirms they are exactly identical.
