A 20 GB hard drive is always 20 * 10^9 bytes. I'm not sure why so many people on the linux-kernel list think otherwise, but the hard drive industry is quite consistent in its use of power-of-10 units to describe capacity. See: http://www.seagate.com/support/kb/disc/bytes.html ("all major disc drive manufactures use decimal values when discussing storage capacity") Answer ID 336 in Maxtor's "Knowledge Base" ("Hard drives are marketed in terms of decimal (base 10) capacity. In decimal notation, one megabyte (MB) is equal to 1,000,000 bytes, and one Gigabyte (GB) is equal to 1,000,000,000 bytes.")
