Last time this happened Gene recommended that I should hit the hard disk
drive with a hammer on startup and it worked :). I was able to backup
important data, but I couldn't backup all data. I noticed that after the
HDD rest for a while, a week or so, it worked better when using the
hammer, resp. I used a slat.
I don't recall using the word hammer without the rubber prefix. That really
is extreme, although I do have an old Maxtor 7120S that needs a pretty good
bump to get it started. Once running, it has no bad sectors yet. The idea
is that you give the drive a good bump, with the ball of your hand, or a
small rubber hammer, striking the corner of the case so that the drives
case is spun a few degrees in the same plane the disks inside turn. This
breaks the heads loose from the disks, which have become so polished that
they stick to the disk like a set of machinists 'Joes Blocks' which are so
highly polished that one can bring them together in whatever thickness you
need to set a gage with, by twisting them. They will remain stuck together
until you twist them again breaking the atomic bond. If the drives case,
and the heads attached to it, can be given enough of a twisting motion
relative to the disks, by a sideways blow on the corner of the case, the
heads will come loose and the drive motor will then have enough power to
get the disks started. The heads will be flying on a film of air, as they
are designed to do, before the disks have turned half a turn. Soft wood
might do as it would dent, cushioning the blow somewhat without damaging
the case casting.
