hdparm -t or dd between the drive and /dev/null or /dev/zero and the drive ( for a destructive write test ). > 2.

Not that I am aware of but it is simply a matter of dividing the current start position by the desired alignment and seeing if you get a remainder or fractional result. parted's align-check command does this, but simply answers with a yes/no as to whether it is aligned instead of how far off it is. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQEcBAEBCgAGBQJWfe+vAAoJEBB5UWFcu6UWcnwH/0Ft7FnlqG3z8WgPyxw/hjtP B6mf9fyPod/XlExE5YioAMIY/mj7u4AwYBHqvRsr7GqhIxc3PNdT31i1gfwi/khp sC+nJj39ShBp3C313MyRm9wbUQgMs88qXQAJWjQwRNs/suWyaSodOAzCsJ96aD0D xiT/9T8s4l3eXSGMeutFCtTRkFh8csOrQTO39Pq6es1uVoZd1fR3VC+HMwfyqt72 CDWhm2EAiAuNBYZ8g0LpD2WLqrh0ZHqui2svLnEZATpc1GsreZyc8jUNDZ9EXFs6 rfQXVXTQqXAHOkQCfF9tD9mLsKUOBN0yDkbl9Zb95gqPRjbqnqEeWq+iWsdSynI= =GLJ8 -----END PGP SIGNATURE-----
