Most drive manufacturers qualify a megabyte as one million bytes and a gigabyte as one billion bytes. This allows them to inflate their numbers slightly. (A megabyte is really 1,048,576 bytes and a GB is really 1,073,741,824 bytes.) FreeBSD, Linux, and Windows all use the "true" definintions when calculating drive sizes. Hence the smaller reported sizes. K.S. On Thu, 8 Apr 1999, Viren R. Shah wrote: : : I just bought an IBM 14GXP 14.4GB drive.
