Roger may be using a valid unit, but he's not using the RIGHT unit,
and Steve is. Hard drive vendors have long used strange units
(compared to the rest of the computing industry) to pad their numbers:
sometimes "1 MB" meant "1000 KB of 1024 bytes each" (1000 KiB), and "1
GB" meant 1000 of those MB. But many now settle on using base-10
powers to describe their drives, since that gives the biggest
significand (the "160" part of "160 GB").
The only hard drive vendor I know of selling "160 GB" drives is
Maxtor; their product manuals say: "Maxtor defines 1 Gigabyte (GB) as
10^9 or 1,000,000,000 bytes of data." It goes on to say that there
are a maximum 320,173,056 of addressible sectors (each 512 bytes) in
LBA mode, for a total of 163.9 GB of space. This makes 152.6 GiB.
Can we be done with this rather silly thread now?
