Whall, on Ford small blocks you get a 302 when you bore out a 289, you could probably go the other direction if you sleeved an old tired 302 block down. ;-) Ted ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"

You think the formatting takes up the missing 16 GB (305 - 289)?

On 2007/02/02 15:18, Peter seems to have typed: > So now my question becomes "Where does FreeBSD get 289 from 305?". Well, for one thing, you never have 305GB. 1024MB = 1GB. You only had 298GB UNFORMATTED. Formatted, you had 289GB. With 8% reserve, you're down to 266GB. Remember the 2MB floppies? 2,000,000 bytes = 1.907MB UNFORMATTED. 1.44 MB formatted. Same principle applies to all disks. Formatting takes space, but makes the disk usable. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
