It obviously cannot be larger than the device unless there's some error, but it can certainly be smaller. > Those 8036139008 bytes do exactly match the first 8036139008 of > the 8036286464 read on the Linux system so it is definitely the > same device. It is quite common that a few sectors at the end of the device (or between partitions) aren't used to keep certain constraints on the layout of the device or the file system.
