IMHO you should be using ddrescue (preferalbly the one from GNU) to cop= y the disks onto new disks (at least the faulty ones). Do this first, s= ince additional access may result in more data loss.

Working live on bad drives isn't something I would recomm= end. --=20 Vennlige hilsener / Best regards roy -- Roy Sigurd Karlsbakk (+47) 98013356 roy@karlsbakk.net http://blogg.karlsbakk.net/ GPG Public key: http://karlsbakk.net/roysigurdkarlsbakk.pubkey.txt -- I all pedagogikk er det essensielt at pensum presenteres intelligibelt.= Det er et element=C3=A6rt imperativ for alle pedagoger =C3=A5 unng=C3=A5= eksessiv anvendelse av idiomer med xenotyp etymologi.
