What you're missing here is the fact that different tools report the sizes differently. Look into the difference between "GiB" and "GB": http://en.wikipedia.org/wiki/Mebibyte you have: 750156.38 MiB = 750156380 KiB = 750156380000 B = 732574589.8 KB = 715404.87 MB = 698.63 GB (with the "i" the factor is 1000, without it, the factor is 1024) HTH, Joost
