Your harddrive vendor lied to you ;) The difference is whether a
K is 1000 bytes, or what it really is, 1024 bytes in hexdecimal,
2's complements that computers use. So (1000/1024)^2, or
0.9536743164 * 60 gigs = 57.22 gigs. Your slight difference, ie,
57.1 <> 57.22 is due to 'df' rounding off to make the output human
readable.
