Hey, I shot in the dark, but cabling might be a culprit. I've had some issues with cables, both with the ridiculously unreliable SATA connectors coming out a little as well as with cables which must have been insufficiently shielded. They all resulted in some similar messages about timeouts. One thing to try if these are 3.0gbs drives would be to jumper them to 1.5 (if possible) and see if that makes a difference. Or try another cable. /Patrik --------------enigC8CD0286BD3D01DB07CB5CFF Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.2 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iD8DBQFEgivnT+KvsdUW5p8RAjorAKCQM/eEvFrfoQBcEv96gheQzawCdQCff3B2 1DxUt8vfq/lEaoGubfcNsF4= =M49L -----END PGP SIGNATURE----- --------------enigC8CD0286BD3D01DB07CB5CFF--
