heads issue and possible media damage. ROM is native?

Most likely preamp is dead as well.
Also can be a motor coil break - we have seen one such drive here.

Where was the fault on the original PCB? Was the 5V TVS diode shorted?

Thanks Labtech!

Yes ROM is native, because Serial : W1Exxxx is the same tath serial in HDD's sticker.

That's good.

Yeah, best is to start eliminating things one by one, starting with simplest.
Besides PCB, preamp may be a problem as well. Check for residue on the media from it should it have blown. Because cleaning after is not fun.

Hi Dmitri

coils looks like tehere are ok.
i test it and measures are about 0,01 ohm

I test de PCB. i think not Diodes in this case.

I think tehre are 4 fuses. i atach pic (not real pic. googled pic)

in case of fuses they are not shorted
measure is: 0.001 Ohm

The motor windings should measure around 1 ohm, maybe less. The zero ohm resistors should measure 0 ohms. You should be using the 200 ohms scale for your measurements.

Did you check whether preamp is good?
Motor coils is possible, but definitely more exotic diagnosis.

Thanks fzabkar!

I used a very simpler scaler, maybe is not very accurate

OK, for some reason you notice the last sentence only :) Disregard the idea about motor coils.
Check the preamp.

Hi guys.

i test inside HDA, no dust on platers and no dust on filter.

I replaced Heads with donnors ones, the drive cames DRY and i have acess to user area.
Now i am trying to clone HDD with DE, but the problem is thath every 10.000 secs read i get 8 secs imposible to read, and every 5 minutes the drive stops, i need manually start another time, and continue:

every 10.000 secs read i get 8 secs imposible to read.
then every 5 minutes the drive stops.
and i need manually start another time.

every 10.000 secs read i get 8 secs imposible to read.
then every 5 minutes the drive stops.
and i need manually start another time.

every 10.000 secs read i get 8 secs imposible to read.
then every 5 minutes the drive stops.
and i need manually start another time.

and so on

any idea?
