Fujitsu MHV2100AT wont spin up -- PATA laptop drive

[egotrip]

Hey guys,

Got a Fujitsu MHV2100AT that wont spin up. I go into the bios and the system doesn't recognize that the hard drive is attached. I then use a USB adapter, again the drive doesnt spin up.

I'm assuming my option is to replace the PCB on it. Any other suggestions?

I read somewhere that the drive heads could be stuck because of inertia and I can dislodge them by "spinning the drive like a frisbee" but I'm not sure how accurate that is.

I have attached pictures of the front and the back so all the information is present.

Can you hear or feel it trying to spin up?

Otherwise show us a photo of the other side of the PCB. I believe there may be a fuse near the IDE connector.

Thanks for the response!

No, there is no sensation of movement or sound when the drive is plugged into either the USB adapter or the laptop itself.

I have taken the pictures you have asked, and just so you know there doesnt appear to be any burn marks on the underside of the PCB.

Thanks again

Here is the fuse:

Ok, I see the fuse. Its tiny and has an N on it.

I cant see much more than that. What are my options at this point?
Thanks!

Measure the resistance of the fuse on the 200 ohms range of a multimeter. It should be close to 0 ohms. If it is open, then measure the resistance between SATA power ground and the load side of the fuse. If there are no shorts on the load side, then replace the fuse, or flow a small blob of solder over it.

Alright, I will see if I can get a friend to help me with this since my limit stops at replacing a PCB

And just to mention it, not sure if it makes a difference but you said SATA power when this is a PATA drive?

[fzabkar]

Sorry, that was another brain fart.

There are several ground pins in the 44 pin IDE connector:

If I'm not able to find someone to assist me in the hardware modifications you mentioned, replacing the PCB would also fix the problem?

If so, any idea where I might find one for this drive?

I believe there may be an 8-pin serial EEPROM underneath the foam, and above the hynix SDRAM. This component, or its contents, would need to be transferred to the donor PCB. It stores unique, drive specific information.

Your local TV/AV repair shop should be able to do this for you. Otherwise ask your board supplier if they offer a ROM transfer service. Such a service should cost no more than US$10 - $20.
