Next time read the content of the ROM with external programmer and SOIC8 clip, or better yet use something like WDR 4.0 Free demo to read the content of the chip without swaping it, because it's obviouse that you can't do the task (soldering surface mounted components) properly ....

Hi,
the shorted pins are connected on PCB - that's why I shorted them.
Both EEproms are still working. I desoldered them with hot-air-Station. After that, I removed the solder with desoldering wick. Unfortunately, I used a wrong soldering tip and that's the reason for the ripped pad and dark stain. Next, I soldered them both (old and new one) with a flux pen. That's why you can't read the label.
Please have a look on the old PCB. It looks better. I know, the EEprom you mentioned is soldered in a bad way.

Judging by the recorded sound, heads are not stuck at all.



Cool .....



Tell that to the owner of the drive instead .....

Can you read the contents of the ROM for the 2 PCBs using WDR tool ? DON'T WRITE ON IT, JUST TRY TO READ IT.

We know the situation is getting worse. What is going to be done about it?

Thanks for the answer.
But why does the new PCB don't start with old EEprom (imagine EEprom is ok)?

God..dammnned! You're just making someone else's repair bill go 2x higher.

How it "looks" inside the by-now-overheated chip is more important. Did you not work quickly enough? Use too much heat too long? Not use a shield over the chip, thus heating the body too? Why are you experimenting on someone else' critical work?

I will try WDR.

I'm going to test WDR. Is WDR able to work over USB or do I have to conntect the HDD to SATA?

MCU Can't read the contents of Flash ROM chip / the contents can't be loaded to RAM.
PCB Without ROM connected to drive will not even spin if you power it up. The same if ROM is damaged or can't be read ...

Status quo:
- Old HDD spins up with old PCB
- New HDD works with it's own PCB (with bad soldered EEprom)

- Old HDD didn't spin up with new PCB (with changed EEprom)

Does WDR run with wine and over SATA-USB-Interface?

Are you SURE of that ?
Attached picture is for a diferent WD drive, yet i don't think the legs of the SPI Flash ROM chip are suposed to be shorted ...

I'm really sure. Nevertheless, I ripped that pad off after I tested this new PCB with the old EEprom. It's now shorted and is still working (new HDD with it's own working PCB and EEprom).

Ok, maybe it's diferent on ROYL family then .....
Again, read/dump the content of the ROM for the 2 pcb s.

To be sure of being sure, you need to see the pertinent schematic.

- Run the program
- Options - Ports - Select the port where you have the WD connected.
- Be sure that "Safe Mode" is selected
- HDD - WD-ROYL
- Click on the icon of the ROM chip
- Read the chip.

Do that for the 2 PCBs.

DON'T WRITE ON IT.

Post the bin files here.

Yes, i know, but i don't have it, i don't have schematic for the ROYL drives.
Yet i would assume that the SPI Flash ROM pinout would be the same and it doesn't make sense for the legs to be shorted, at least to me ....

When you stop?!! I've read your last 4 posts on this topic. If you can't say anything than..."seed a pro" (perhaps like you) then say it once an go away!! You don't help anybody performing like this. I like to believe that everyone who ask for help here knows that with a software click or a hand shake could ruin forever the data. If that happens at a "pro store" and i'm sure that happens...they would simply tell you..sorry...we've done what we could. there is no malpraxis in this "world"!!

Spildit realty helps around..well... as much it's possible.

You have to connect HDD to sata and find SATA port on the software.

Option - Port - Costum - Scan PCI
