No way= to improperly align anything if a drive honestly tells it has 4K/4K logical/physical sector. --=20 With respect, Roman --Sig_/0P04owr=KfW9Pk_8sgO/eLZ Content-Type: application/pgp-signature; name=signature.asc Content-Disposition: attachment; filename=signature.asc -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (GNU/Linux) iEYEARECAAYFAk3Z+ccACgkQTLKSvz+PZwgznACcD7uJNqgLlYcojds0iHcvsaD8 BWEAnREY4U08j9J0W8zaNnMpH4cSI0Xj =05I2 -----END PGP SIGNATURE----- --Sig_/0P04owr=KfW9Pk_8sgO/eLZ--
