Very interesting I would like to see this behaviour to make some experiments. I would like to simulate an unreadable sector... I see --make-bad-sector in hdparm, does that simulate an unreadable sector faithfully? (e.g. will it even be recorded in SMART current_pending_sector / reallocated_sector_ct ?) Also, how do I trigger a link reset manually? Thank you
