Nowhere. |

Disk manufacturers measure kilos of data as 1000 |
49 |
Everyone else measures it in 1024 |
50 |
|
51 |
They do this because it fudges disk sizes to appear 2.4% bigger than |
52 |
they really are. |
53 |
|
54 |
When you get into TB drives, it gets worse as 1024*1024*1024*1024 |
55 |
differs from 1000*1000*1000*1000 bu a lot more than 2.4% |
