'[OT]: What to do on a HD that doesn't run?'

Hello,

   I have a 4.3GB HD from Sansung whose plate motor seens to be locked.
When I attach it on a computer and turn it on I don't hear the typical noise
of an HD motor running at high speed.

   Someone have an idea of what I can do with it?

   Thank you very much,

   Brusque

Smack it on it one of its edges. It is possible that the heads have
stuck to the platter and the shock will dislodge them.
Used to happen quite a lot on early (20MB) Seagate drives.
If the heads are really stuck, they will tear off when the drive motor
spins and you'll hear some horrid noises from your now junk drive.

If the electronics are toast, you can try swapping them with known
good electronics from another IDENTICAL drive. Your bad block tables
will be wrong, depending on whether the firmware stores them or reads
them from a 'protected' area of the drive, but you should be able
to retrieve your data.

Have you tried connecting JUST the power connector to the drive?
I have had instances where a reversed IDE connection has prevented
a drive from spinning up.

If all you want to do is get data off, open the lid & try to
hand-start (without touching the platters) If it starts, copy stuff
off and throw it away (after stripping out the neodymium magnets, of
course : http://www.netcomuk.co.uk/~wwl/neodym.html )
Take care not to breathe on the platters as the condensation makes the
heads stick - this can be rather spectacular if done at speed...!

We used to get this a lot when I worked as an IT manager.

What we used to do was to hold the drive on its edge and gently bump it
against a padded surface in the axis the platters spin (in a twisting type
of motion). I've still got a 4.7gb drive that occasionaly does this. In
extreme cases we used to do it with the power attached to give the drive
that extra oomph to get the platters spinning. It seems that the bearings
sometimes seize on the cylinders or get stiff with age.

Worth a try

I used to have an old 8086 laptop which had a drive like this. It just would
not start unless the end of the spindle was given a flick ( the spindle came
outside the sealed unit). Eventually with nothing to lose I took the cover
off, and found the heads stuck with what looked like oil.

It seems that what happens with older drives is that the oil seeps past the
seals in the spindle bearings, and radiates out on the platters as the disk
spins. Provided that the drive is spinning, the layer of oil is thin enough
that the heads do not stick to it. Once the heads go to the landing zone on
the inside of the disk then land, they collect the oil and it "glues" the
head to the platter and the motor does not have enough torque to unstick it
again.

This problem seems to have gone away as drive technology has improved, but
it seems there is still the odd bearing where the seal is not as good as it
could be and the oil seeps out.


The other trick that I have seen is where a drive will spin up, then spin
down. This was an affliction of Micropolis 1300 series drives. The flexible
cable going to the heads goes around a sharp edge, and the continual flexing
of the cable in operation causes cracks in the wiring. If the heads go to
the landing position the extra stress on the cable pulls the cracks apart so
there is no longer any signal from the heads. As the electronics gets no
reference track signal, it decides something is stuffed, and spins down. In
desperation it was sometimes possible to shake the drive at the critical
time to move the heads from the landing position, which allowed the cracked
wires in the cable to make contact again and the drive would typically keep
going long enough to get the data off it.

Check 12V supply in harddisk cirquit board.
I had a HD that got a solder jount crack in 12V supply.

Maybe also check motor coil connectors.

There are HD:s that are stoppable/startable by the driver/OS.  Maybe something wrong in BIOS setup...? (long shot)

Hi All,

Speaking of faults on drives ETC, *drives* (esp syquest ones) have pico
fuses on the inputs of the supply plug and Zenner diodes after the fuses.

I have a collection of drives here that all they needed were 1- 2 new pico
fuses and a zener.

Regards,

Kat.

   little finger smacks on drive edges with the power connector plugged
cured it.

   Thank you very much,

I once bathed a Conner 2020 laptop drive in freon and made it work for a
while after that. This is a more or less standard cleaning method for
platters so it is not very far from what the manufacturer does. Except I
also powered the drive with the freon on it.
