Do Not Swap Circuit Board on Hard Drive If you Care about Data

If you question any professional data recovery specialist about swapping circuit boards on drives. The answer will be the same: Under no circumstances do NOT try swapping the circuit board on damaged, faulty hard drive with one from another drive.

Technically, if you do NOT care much about data and willing to take a chances to experiment, you need to find the identical model of the failed hard drive and try PSB swapping.

Yes, in some exceptional cases it might work, but for the certain hard disk models only. All other ( 95+%) of hard drives will start clicking, or simply failed to be recognized by computer’s BIOS.

Replacing the printed circuit board may very well cause a mechanical failure and render your salvageable data unrecoverable. Moreover, switching boards will not work in most cases. The explanation to this is quiet simple, if you are a professional data recovery engineer: the drive information carried on its controller board is unique for each particular drive for certain models; other models required certain firmware version, matched chipset on board, site code, and so on.

Why is some firmware on PCB unique and practically makes the hard disk unrecoverable if it happens the original board is missed or lost? That’s because some drives fail to start if the tiny piece of microcode on PCB is not matched with the identical data on the spinning hard disk inside the drive.

Before shipping your hard drive for data recovery:
MAKE SURE the failed /damaged hard drive has its original PCB on it.
Regardless the PCB condition, e.g. missed/burned elements on it, the hard drive must have its own original board.

Needless to say that our lab is well equipped to repair hard drive and bring it up to the shape, when data reading is available from the disk. When is required, our specialists re-solder elements on the board (including main processor microchip), re-program ROM, and restore firmware microcode. As that is all part of the data recovery process by professionals.

What Our Customers Say...

From John A. Upper Marlboro, MD USA: Samsung SP0802N - I placed one working drive on top of another to get at a screw. The phone rang and I answered it about 10 minutes later I completed screwing the drives into their places. The screen was frozen. I rebooted and it never got into the OS as it said a file had been corrupted. I ran check disk and it told me that the c-drive was good. It would not complete a check disk on the d-drive as one or more files are corrupted. I had a local company come to my home as their advertisement said the do data recovery. A waste of money. The technician listened to what I said. Tried to boot it using my software and then he said the drive was not spinning. I told him that he had to be mistaken as I had successfully run chkdsk. He was not fazed. Although he pointed out a capacitor or a resistor on the drive and noted it had been damaged. It is on the left side of the drive about an inch and a half down from the bar code. He stated he could not do anything for me at that point and charged $75 for his service.

Thanks again for your help. I appreciate the items you were able to save. I will definitely recommend your services to others--have a Blessed Day.

From H-Tzer C. Geneva SWITZERLAND: Western Digital WD10JPVT laptop - Not spinning

Thank you for the nice work done. I received the recovered data on the external HDD. Sure I'll recommend you to anyone if needed.

From Gary D. Fredericksburg, TX USA: Toshiba MK2018GAP laptop - Drive failed to boot, started making grinding sound.

Hello,
I'm very pleased with the outcome of your recovery services. The Hitachi HDD-clone 'did' work and a 40 gig instead of the original 20 gig, thanks. All is well which ended well and I'll recommend your company to others that might end up in such a situation.
Prosperity to you all,
Gary
