HDD halott?

Van egy 2,5"-os, 500 GB-os Toshiba merevlemezem, eddig egy netbookban volt. Nem sokat használtam, de SMART 100%-osnak írta.

Közben befigyelt egy androidos DVB-T settopbox, így vettem egy USB házat neki, ami értelemszerűen Y-kábellel csatlakozik a géphez.
A gépre hiába dugom fel, azt sem írni, sem formázni nem tudom. Ha mégis, az eredmény olvashatatlan, a gép nem csatolja fel a partíciót, még ha ext4 sem.
