Submission + - Apple kicks HDD marketing debate into high gear 2

quacking duck writes: With the release of Mac OS X 10.6 "Snow Leopard," Apple has updated a support document describing how their new operating system reports capacities of hard drives and other media. It has sided with hard drive makers who for years have advertised capacities as "1 GB = 1,000,000,000 bytes" instead of the traditional computer science definition, and in so doing has kicked the debate between marketing and computer science into high gear.

Binary prefixes for binary units (e.g. GiB for "gibibyte") have been promoted by the International Electrotechnical Commission and endorsed by IEEE and other standards organizations, but to date there's been limited acceptance (though manufacturers have wholeheartedly accepted the "new" definitions for GB and TB). Is Apple's move the first major step in forcing computer science to adopt the more awkward binary prefixes, breaking decades of accepted (if technically inaccurate) usage of SI prefixes?

    So let me get this straight ... i download a 4.4Gb File ... and it magically becomes a 4.6gb file in finder.

    And if i dont know this i just assume that it wont fit in a 4.4 DVD unless they include special glasses which make the 4.4 in the dvd read as 4.6....
    • Actually, all DVD[-RW]* manufacturers label disc capacity as 4.7 GB, so in that case it would be more straight forward. You'll need magical mind glasses that'll force you to see what they are actually printing.

The wages of sin are high but you get your money's worth.
