Don't be told. Do the math. 320,000,000,000 bytes (hard drive manufacturer 'gigabytes'), divided by 1024 gives 312,500,000 kbytes, divided by 1024 gives 305,175.8 mbytes, divided by 1024 gives 298.023 gbytes according to a quick dc(1). -- Matthew Fuller (MF4839) | fullermd@over-yonder.net Systems/Network Administrator | http://www.over-yonder.net/~fullermd/ On the Internet, nobody can hear you scream.
