Where is the diode?

[tom58]

Fried the drive......again.

Last time I just popped off the TVS diode and life was good for data recovery.

Anyone know where it is on this one?

The two right under you power connector. Test them

Can you please clarify "test them".

I have a Fluke Digital Multimeter (auto range); should I just set it to resistance mode and check for a dead short? Or use the continuity checker that beeps of shorted?

Thanks

Thanks for the cryptic answer. You couldn't just post a couple of simple instructions specific to testing the diodes on-board on a Harddrive here?

Before you guys go "randomly" probing about for "diodes" be aware that some cheap multi testers use a 9v battery.

so if you have your multi-tester set to "sounder", there is a possibility you can damage some of the Cmos inputs for some chips if you reverse bias the substrate of the device.

In English :
You can seriously shorten the life of some chips , by using the wrong analysis protocols
and please ALWAYS remember you anti-static wrist strap with integral resistor and grounding wire.
(notice that all these "pro" disk repair kits do not come with a cheap reusable $3.00 antistatic wrist band)

Remember safe repair is like safe sex: always wear the correct protection.

No, you wouldn't learn anything by me telling you how to test a simple diode.

What is the open circuit voltage and short circuit current of a cheap multimeter?

You don't check a diode with Ohm Meter, check it with a Diode tester option.
