- So why are floppies called 1,2M and 1,44M, when they are exactly 1,2*1024*1024
- and 1,44*1024*1024 ?
- And hard disks 213M when they are 213,000,000 ? I just recently bought a hard
- disk advertised as a 180M Conner. On the hard disk itself, however, there was a
- label of 170M, and MS-DOS Fdisk reports only 162.5M. A call to the vendor gave
- me the following story: The hard disk is 180M unformatted, formatted it should
- be 170M, which it almost was (169...).
- But the thing I don't understand is that the Norton programs call it a 166M
- drive.
- Any explanations/comments?
