You'll need to provide some more details such as how old your FreeBSD 8 is, drive model number, controller details and the actual error message you are getting. I recently bought a Hitachi Deskstar 7K2000, which is sitting in an Astone enclosure (identifying as "Sunplus Technology Co.,Ltd."). Unfortunately, I'm limited to USB2 whilst I wait for the correct eSATA adapter. Whilst the first disk was DOA, its replacement is running perfectly (though slowly) with my 2-week-old FreeBSD 8.1-stable. In particular, one of the first tests I did was to write a pseudo-random sequence over the entire surface and then verify it to ensure that all sectors are uniquely addressable. --=20 Peter Jeremy --qDbXVdCdHGoSgWSk Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.15 (FreeBSD) iEYEARECAAYFAky8p9IACgkQ/opHv/APuIcZ4ACgmNmFnfd3MHew+6dSQktTKH+G MU0An3SZquOX2hdDSCmS7PngyenWypl0 =9Mco -----END PGP SIGNATURE----- --qDbXVdCdHGoSgWSk--
