I need to find a PCB for this drive. Appreciate any help locating. Bought similar model HD on Ebay but slightly different PCB unfortunately, so no joy. Can't find anything current on Ebay and am not sure of PCB model #. Is it printed on white sticker? Anyway, have tried googling all numbers from sticker and chips but still no luck.

White Sticker:
0A29778
BA2798-
Z2R837
0A53

rectangular chip:
Samsung 725
K4S281632I-UC60

printed on PCB:
110 0A900026 01

Why do you need a new pcb?

Data recovery. Drive won't spin up.

Need a higher resolution picture. What do you think happened for the board not to spin?

I'll try to get a better resolution picture of the board up in a few minutes.

No idea on what happened to the drive. It belongs to a client and came out of a G-Tech G-Drive.

As an evaluation prerequisite, it is a good idea to ask customers what they think happened with the drive.

It may help validate some of the findings when running tests.

I did ask. The client had no idea.

Pictures attached are close ups of chips on PCB

The diode seems like it may be burnt, but cannot quite tell. Need a better picture, preferably taken from up top.

Search for diode here on the forum to learn how to test using a multimeter.

Will do, thanks for the suggestion. Just gotta locate my multimeter.

Will also try to get a better pic - been farming the pics out to my wife after failing with my original iphone pics.

Various pics of the diodes, etc.

Cannot locate test leads for multimeter!

It's got the clamp leads on it which makes testing small diodes difficult. Have ordered replacement set from Mouser, but the diodes don't look physically burned out to the naked eye. Sorry about the small pix.

Anyone on the board do PCB repairs and wants to take a look at this one? For pay, of course.

I"ve seen posts about flashing firmware on PCB's to make them work with different hard drives. I have an almost identical PCB from the same model hard drive. Can I flash the firmware to make it work with this drive?

"Almost identical" is not enough to say if it will work or not. Typically, matching the first two lines on the PCB's white label should make board compatible. This is just the starting point for this. Then you have to make donor PCB work with the drive by transferring adaptive information.

Can you hear some "buzz" noise from the drive? If yes, forget about PCB exchange - most likely the diagnose is "head stiction".

No buzz. Drive just did not spin up at all. With donor PCB (from board with same two lines on white label), the drive would spin up but would not read. Tried swapping ROM chip from original board to donor board, but same result.

Hi Everyone

Apologies to re-ignite an old post, but I have almost the exact same HDD/PCB that is being talked about here, with exactly the same problem, and stupidly, it houses the only copy of some very very important data. I am going to have to bite the bullet if I cant fix this myself and take it to a professional recovery place, but if I can save £500 (or USD $750) then all the better.

So here is what happened:

The HDD in question is from a G-RAID 2 1TB Enclosure, which as far as I am aware was setup as RAID 0. This RAID has been working without fault since it was bought in 2009, and a few days ago, after being brought home from a visit to my workplace, does not work. The light comes on, I can hear the fan start, but aside from that, NOTHING. Not mounting on a PC or mac, with multiple AC adapters and firewire/usb cables being tested - NOTHING.

I then opened up the enclosure as it is way out of the warranty period. All appears to be in order - nothing is burned, broken or looking bad to me. There are 2 x 500gb drives inside (striped to make 1TB) and they sit one on top of the other with a cradle in between them. Having fired it up again, I realised that the drive at the top is spinning, no bad noises, all fine. But the bottom drive - is not. No buzzing, no spinning, no vibrations - NOTHING at all.

I then thought I should test both drives individually, so I went out and bought a SATA-USB caddy. Again, the drive that is powering up, still powers up in the caddy, the drive didn't - still DOES NOT!

I get a "this disk must be initialized" error when I mount the one that powers up on my mac - which makes sense to me as they are a striped RAID set so they need to be mounted together. I did a deep scan last night with that drive on disk drill - but as expected, only very small documents or pictures were appearing properly, everything else does not appear at all and if it does, its garbled. Please correct me if I am wrong but this is because there are fragments of these files on both drives which have to be present to use these files properly.

Now, what I need to know is, what are my options? I have read alot of forums where people have had success by replacing PCB Boards and ROM Chips and the drive has worked again. I have also read other stories where it hasnt and the only option is then data recovery. I have uploaded pictures of:

G-RAID Sticker at the bottom of the Enclosure
Sticker on top of the HDD
Sticker on the PCB Board

Please please can ANYONE help?!

Thanks

Taj

Is this a test?

The PCB is missing the NVRAM chip!

i have this pcb fuzztone65 you want to buy ?
