Re: Drive Sizes
Bernie,
Your clarification is not quite right. The *size* (capacity) is *not* just
defined in terms of formatted and unformatted, it's also "defined" by
*marketing* persons in one more fashion: marketing calls a megabyte
1,000,000 bytes ! (Makes the drive seem bigger than it really is.)
I've seen this on drives (or their accompanying literature), Wolf knows
about it, Al mentioned it to Derek, and Derek said, "Yes. I found this on
their site "Western Digital defines a megabyte (MB) as 1,000,000 bytes and a
gigabyte (GB) as 1,000,000,000 bytes"". I had trouble finding that specific
info myself until I searched WD's site for "defines a megabyte"; don't know
how Derek found it :)
While we know this definition is *wrong*, it's how drives are *labeled* by
their manufacturers, so it's mildly important to know it.
