 Isn't this the classic case of the OS using a base of 1024 to calculate=20
 size and the hard drive manufacturer using 1000 for the same purpose? =20
 My "3TB" Western Digital Drives show 3.0 TB using smartctl -a and 2.7 TB =
 
 using diskinfo -v.  I get the same 2.7 TB when I manually divide the=20
 media size in bytes by 1024 four separate times.
 
 Respectfully,
