It shouldn't be a problem. Geometries nowdays aren't as useful as they used to be and aren't really used much, LBA alleviates most of that. The geometries that FreeBSD uses aren't the same that the drive internally uses. In fact, using geometries has been the cause of an old 8 gig limit on hard drives, a newer 137 gig limit, and an old boot loader problem booting anything over cylinder 1023. As for the missing 8 gigs, that's probably because your hard drive manufacture used SI units (10^3=3D1000) instead of the standard units (2^10=3D1024) just to make the number look bigger. My 250 gig drive is only 238 gig in reality. >=20 > - ------------------------------ > Mike Loiterman > grantADLER > Tel: 630-302-4944 > Fax: 773-442-0992 > Email: mike@ascendency.net > PGP Key: 0xD1B9D18E >=20 > -----BEGIN PGP SIGNATURE----- > Version: PGP 8.1 >=20 > iQA/AwUBQjJw02jZbUnRudGOEQIFgACghb4rW7h8yi7Gy51D427MDeIlfMQAn1b5 > v4YVKUhIT9gwS6SZBMDDwYK0 > =3DKtaI > -----END PGP SIGNATURE----- >=20 > _______________________________________________ > freebsd-questions@freebsd.org mailing list > http://lists.freebsd.org/mailman/listinfo/freebsd-questions > To unsubscribe, send any mail to "freebsd-questions-unsubscribe@freebsd.o= rg" --=20 I sense much NT in you.
