Re:Free disk space: 1.21 Giblets (Score 1)

I don't think it's ever been very ambiguous. Once a hard drive is formatted, file sizes and available space are always reported in powers-of-two units by the OS. At the logical level, powers-of-ten units are simply not used.

Only some hard drive manufacturers have used the powers-of-ten definition; but hard drives always have less usable space than the advertised capacity, since they're reporting the physical capacity before the drive is formatted with a file system. Either way, users would still perceive a discrepancy between the space available to them and the number on the box.
