Hard drive not working - burnt PCB?

chris0147 · 03-03-2012, 10:41 AM

Hi guys,

I need your help as I have got a problem with the hard drive. This morning the hard drive was working fine and there was no clicking noise. I was working on the hard drive to get the partition table to restore as it has been corrupted due to raw format. When I ran the test disk, it took me ages to complete the method to restore the partition, but I didn't realised what went wrong then the program started to stop working. I found out that the hard drive have stop working and it won't spin up when I tried with each different internal power connector. I have tried with my own hard drive which it works fine, so I guess the hard drive is dead.

However, I have looked at the PCB to find out why the hard drive won't spin up. I suspected as I can still see myself that the spindle motor wiring on the PCB to engaged with the motor axis to allows the platters to spins, is burnt. :(

Here's the picture:

Does anybody know if it have been burnt and where i can get a replacement PCB for this drive? If I get a replacement PCB is there even a good chance it would work again? It's an obvious to me that it have been burnt, it didn't go through the motor axis to make the platters to spins.

The model for that hard drive is MAXTOR 40gb DiamondMax Plus 8 and PCB is MZTCVGBRB5334A REV A.

Any advice would be much appreciated.

Thanks in advance

I wonder whether the spindle motor overheating/sticking didn't cause the contacts to burn out, especially given the work the drive was being put to.

Thats a really OLD drive so finding a replacement may be difficult have you checked E-BAY ? Why spend the $$ for an old 40GB drive ?

greenbrucelee · 03-03-2012, 02:43 PM

yes it looks burnt but for a drive that old what could you expect?

Measure the resistances between each pair of motor terminals (phases A,B, and C), and between each phase and the common terminal. Do this at the motor, not the PCB.

If the motor is bad, then a PCB will be a waste of money.

I don't care what you are saying, but it's not my hard drive and it's my brother's so who do you think you are.

I have checked on ebay and i can find the same hard drive, but i can't find the parts to get spindle motor wiring for that hard drive. Do I need to buy the pcb or if it possible to buy the spindle motor wiring?

if so could you post the link?

well its not my hard drive but its my brother and he want it get fix because he has got important files in that hard drive which he have forgotten to backup.

As you can see the picture of the burnt spindle motor wiring, do I need to replace the pcb or the spindle motor wiring and is it possible to get it working again?

Using antagonising language will not help you get a response or any help.

why not transfer the files from the disc to another disc or follow the advice in post 5.

I can't!!!! The hard drive won't boot up on boots, you can still see the pic on above as the spindle motor wiring is burnt, so i still want to know if it can be replacement and where i can get one from?

greenbrucelee · 03-05-2012, 10:11 AM

you dont need a pc to do it put it ina caddy or go to computer shop that will do it for you

post 5 is the correct answer

chris0147 · 03-05-2012, 10:18 AM

Yeah I know what you are saying, but you said "why not transfer the files from the disc to another disc" so I am saying that I can't transfer the files because the hard drive won't spin up.

I still need to know if i would need a new spindle motor wiring or if it would need to be soldering?

I have looked on ebay and it does have the same hard drive as I have got, but it only come with the whole hard drive. I am not too sure if it possible to get a new spindle motor wiring and where I could get one from?

greenbrucelee · 03-05-2012, 10:20 AM

you will have to buy the drive

**LMiller7** · 03-05-2012, 11:20 AM

Hard drive manufacturers do not make replacement parts available for their drives. To get one you would need to obtain a donor drive which in many cases must be a close match with the problem drive.

It's just worth all the hassel for an old 40 gig drive. It may or may not work, 50/50 at best. That's why backing up important files is very important.

How many times do you need to be told to MEASURE something?

NOBODY can determine the state of the motor until YOU provide us with MEASUREMENTS.

Go buy a MULTIMETER.

Here's one for FIVE DOLLARS:
Digital Multimeter - Save on this 7 Function Digital Multimeter

I think he is one of those people that wants everyone to do it for him and if something is slightly hard then he wont do it.

Your suggestion was correct.

I have already got one, so why do you need me to measure it and how many volts i need to measure it?

if it said on my multimeter that there is no volts, what i need to do? do i need to soldering the motor or buy a replacement?

Amd_Man · 03-07-2012, 02:59 PM

I would buy a new drive! It's just not worth the time for a 50/50 at best shot of working!

**satrow** · 03-07-2012, 03:03 PM

There won't be any Volts across it, you need to check the resistance as stated in #5 - Ohms it needs to be set for. Did your multimeter not come with a manual?

It's a job I wouldn't even consider unless the potential remuneration was high and the data worth recovering - even then, I'd want to have 2 known good identical drives as donors - and call in someone with better soldering abilities than myself to help out.

chris0147 · 03-08-2012, 03:47 PM

Thanks satrow, yeah I have got manual for my multimeter. I need to know what is the max resistance that I can check with the hard drive and i want to know where i need to point it on the hard drive?

what concern me is if i use too much reading over the max limits, it would blown up the multimeter :(

chris0147 · 03-10-2012, 09:12 AM

does anyone know what is the max resistance that I can check with the hard drive and i want to know where i need to point the wire onto the hard drive?
