What means "clear"? If on a disk there will be a particle of a dust,
its hit under a head most likely will lead to occurrence of a scratch
on a disk and damage of a head.


The main thing - not simply to replace heads, and to make it so that
HDD worked after that. It happens not so simple.
Sorry, but I shall not give the instruction on DIY replacement of
heads. It not on my behalf, the data after that become non-recoverable
;-)

I figured it wasn't that simple. Didn't hurt to ask, though. :)

If you are asking if I re-jumpered and/or
recabled the drive as a master or a slave,

Nope. There is a unique jumper config with those
drives as the only drive on the ribbon cable too.
yes I did these things. In fact, the stamp on the drive
says to leave the jumper off if it is a master only, then
connect to the master connector on the cable.

Yeah, the drive label is misleading on that.

I wish it was that easy...:(

May still be if its the only drive on the ribbon cable.

This is not allways possible - the heads of a number of drives can be
tracked all the way to a clip on the circuit board. It's almost easier
to move the platters across to a working drive.

I have written - " for example " ;-) It does not exclude other ways.

Just out of curiosity: How long does it take you to replace the heads in
a ''standard'' case (i.e. no special problems)? A day? Several days?
A few hours?

All depends on presence of necessary head assembly. If we have it, the
replacement usually take up to 1 hour for replacement process, and few
hours (or days sometimes) to make a sector-by-sector copy (it depends
on a condition of a disk). And for exotic models search for head
assembly can take some days or weeks...

So the actual replacement is pretty fast. Surprising.
I would have expected a day or so.
That finding the spares can be hard is no surprise at all. ;-)

Thanks for the info!

Not really. Harddrives would cost a fortune it it was that difficult.
It is either pretty simple or undoable.

Mounting heads in the factory is automatized, robotic work.
We are talking about manual work here. A completely different
thing.

In addition the heads in the factory are prepared for installation,
while transferring heads is different.
