I can clear the 80G/72G thing up right now (since it's something I complain about a lot.) The HDD manufacturer considers 1G to be 1,000,000,000 Just about everyone else in the computer world considers 1G to be 1024 * 1024 * 1024. Thus, what the HDD manufacturere calls 80G, computer OSes calculated to be 72G. You didn't lose the space to formatting, you appeared to lose it to a marketing gimick. By using 1,000,000,000 a 1G, drives appear to be larger than if you use the same system everyone else uses. Unfortunately, there's no standards body that has stated what the value is for a G, so the HDD manufacturers are free to do whatever they want. -- Bill Moran Potential Technology http://www.potentialtech.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
