No magic - just multiply the numbers together. 63 sectors per track, 16 tracks (heads) per cyliner, and 6218 cylinders is 6267744 sectors. If each sector is 512 bytes - which is normal - then the drive is around 3 Gig. http://www.mired.org/home/mwm/ Independent WWW/Perforce/FreeBSD/Unix consultant, email for more information.
