Samsung Hard Drive PCB Circuit Boards

June 10th, 2015 Comments off

Samsung Hard drives that do not spin up after the power has been supplied can be diagnosed as PCB failure. Because data recovery service is very expensive, sometimes we would prefer to swap PCB ourselves.

To find a matching replacement PCB, you should find out the PCB number which is etched on the PCB(begin with BF41-), see the following image:

What is Samsung HDD PCB’s BIOS Chip?

All of the 8pins (4 pins on each sides) with 25P05VP, 25P10VP, 25F512, 25F1024, 25F1024AN, SST25VF512, SST25VF010, etc. are the BIOS chip. It is easy to be found because there are not many 8pins chips on the PCB.

In most cases, you should exchange the BIOS before you swap hard drive pcb. You should have certain technique.

Western Digital Controller Board burnt

June 3rd, 2015 Comments off

Question:
I have a Western Digital 1TB hard disk -32MB cache, details are:

Model: WD10EADS-11M2B2
Date: April 2010
Control Board Number: 2060-701640-007 REV A

I am referring to the number that is etched on the board and not the one printed on the paper sticker on the board.

Problem:
The drive is currently not usable because a chip in Controller Board (SMOOTH Motor controller) is burnt and the drive is inaccessible and I want the data in it.

Answer:

You can swap PCB to try. Please refer: http://www.hddzone.com/wd-2060701640007-pcb-p-281.html. You need to change the BIOS chip before swapping PCB.

We know PCB includes 2 parts: Hardware (components) and Firmware (data in the chip); The firmware includes HDD’s unique configuration data. The HDD needs this unique configuration data to work. In order to have same circuit board firmware, we have to transfer the unique configuration data from the bad board to the good donor board.

How To Swap Hard Drive PCB

January 2nd, 2013 Comments off

As we know:  HDD can’t spin; board/chip be burnt; interface broken; etc. These problems are caused by PCB malfunction. Swap PCB of your hard drives can resolve the problems.

Which HDD’s problems are not caused by PCB:
HDD has a buzzing voice or a sound like it is trying to spin.
HDD can spin. However, it makes a lower clicking noise. It spins for a moment and then slow down.
HDD will power up normally (no ticking noises, errors etc) but will not be recognized by the computer
HDD will power up normally and be recognized correctly but will report a size of 0 bytes
HDD will power up but report SMART errors on boot

Hard Drive PCB Circuit Boards:

1. Seagate HDD PCB

These hard drives have 2 architectures: Barracuda (older) and F3 (new generation).

Barracuda Architecture. These hard drives have a dot (.) in the firmware version (“3.CDA”, “8.01”, “3.03”, etc.). Most PCB swaps are simple (~85%). In the other 15%, a ROM chip must be swapped.

F3 Architecture. Hard drives have no dot (.) in the firmware version (“CC44”, “0005HPM1”, “SD01”, etc.). The 8-legged firmware chip will have a number starting with 25, and must be transferred to a new circuit board.

Note: If your hard drive has a new PCB recognized by incorrect parameters (such as wrong model, different SN, or incorrect firmware), you must swap the chip.

2. Western Digital HDD PCB

WD has 2 types of PCBs.

Type 1 has an 8-legged U12 ROM chip that must be swapped.

Type 2 has a missing U12 chip, and PCB firmware is stored in the big “M” Marvell Controller Chip. That chip can be transferred.

3. Samsung HDD PCB

Most of the time there is no need for adaptation service, but in some cases an 8-legged firmware chip (with a number starting with 25) must be transferred.

4. Maxtor HDD PCB

Adaptation service not required. A simple PCB replacement should work.

5. Toshiba HDD PCB

Most Toshiba boards have an 8-legged firmware chip that must be swapped. The chip will have a number starting with 25.

For some Toshiba families, the chip might be missing unique adaptive data stored in the large controller chip. That chip can be transferred.

6. Hitachi and IBM HDD PCB

All Hitachi and IBM circuit boards have an 8-legged firmware chip that has a number starting with 25.

7. Fujitsu HDD PCB

PCB adaptation is not required, but occasionally, a firmware chip transfer is required.

In most cases, swap PCB is not directly change the fault PCB with the donor PCB. Should confirm the donor PCB should be adapted for the HDD.

Most HDD boards have the BIOS (ROM or NVRAM chip) which includes the unique data to access the HDD system area. If the BIOS information is not compatible with your HDD, there is no way to read the HDD’s data. Because of this, we should use the original PCB’s BISO when we swap PCB.

BIOS is the 8pins (4 pins on each sides) with 25P05VP、25P10VP、25F512、25F1024、25F1024AN、SST25VF512、SST25VF010, etc.

How to change BIOS
You can move the BIOS from your original PCB by using hot-air gun, then solder it on the replacement board. Or you can find the electronics repair shop to help you.

If there is no BIOS on the PCB, it means the BIOS is integrated on the Main Controller IC
You should exchange the Main Controller IC to let the HDD be recognized. Move the Main Controller IC (the biggest chip on the board) is complex jobs which need you have certain technique. Some electronics repair shop can do it.

Fix Hard Drive PCB Board

1. I have a Maxtor DiamondMax Plus 8 hard drive that I am trying to recover the files from. When the drive is connected, it’s beeping with loud noise. Also, I don’t see any activity in the computer when it’s connected. Would the PCB board swap fix my problem? How do I choose the proper board?

My drive is manufactured on: 24July2003
Size: 40GB
Type: ATA
Code: NAR61590
LBA: 80293248
I appreciate any help.
Regards,

2. I believe I need a replacement PCB for one of my 500GB Seagate drives.  Powered down last night fine, powered up today and BIOS does not see it.  Drive spins up fine, no clicking sounds.  Removed it from PC and docked it in an external SATA USB dock, still not recognized.  This was one of two “identical” drives that I had bought years ago.  After trying to swap PCB boards, found out that the two PCB boards were actually not identical.

Here is the drive and PCB info:

DRIVE INFO
Seagate Barracuda 7200.11
ST: 3500320AS
P/N: 9BX154-303
Firmware: SD15
Date code: 08384
Site code: WUXISG
WWN: 5-000C50-00B6DA1FA
STX – ST3500320 AS(B)

PCB MOLD INFO
08051 78054 molex 100438797

PCB INFO
PCB: 100466725
REV A DLAJ-4
GTC 12V-O
0807-74-38
PCB sticker: 100468974 H M837K380
MAIN CONTROLLER IC: LSI TTB5501D
HDD Motor Combo IC: SMOOTH 100369972

I think I found the board on your website.  Once I order the $39.00 replacement board, do I need to exchange the BIOS/Main Controller IC before I swap the hard drive PCB?  That does not sound like something that one could easily do.
