Indeed this may indicate vibration > or other external sources of errors. That drive is most likely a Seagate, and if so, there's nothing to worry about. Literally every Seagate drive will have a high value in Hardware_ECC_Recovered, it's just a peculiarity of their SMART. Other vendo= rs' drives recover read errors using ECC too, but don't report that into the SM= ART metric. --=20 With respect, Roman --Sig_/3xuTBvJckA.nglvCUrTg2F9 Content-Type: application/pgp-signature; name=signature.asc Content-Disposition: attachment; filename=signature.asc -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.10 (GNU/Linux) iEYEARECAAYFAkxQnOQACgkQTLKSvz+PZwiQxQCcDKGJSf3FShufSemWtEPzFQbq l4UAoIPSW+aSKkLPsWU7N+APpI04fvQK =r3oa -----END PGP SIGNATURE----- --Sig_/3xuTBvJckA.nglvCUrTg2F9--
