Western Digital HDDs’ Noise related to PCB

July 17th, 2012 Comments off

Causes & Solutions of Two Main types of Noise Which is occured in Western Digital HDDs (Especially Related To L-shape PCBs)

Clicking Noise and Continuous Noise

1- The Clicking Noise
when u power on the hard drive u will hear a noise like (click,click….click,click…click,click)
this noise may be related to the head stack or PCB, the first thing you have to do is to check the PCB By The following steps:

  1. first you have to clean the Whole PCB With a Solvent & Toothbruch then wipe it with a piece of smooth handkerchief to remove the dust & dirt from it.
    Caution: Cleaning of the PCB must be done carefully to avoid removal of any small electronic components.
  2. Check the Resistor (R120) , [ the right value of this Resistor is (0.12 Ohm) ] ,u may adjust ur multimeter to Resistor Measuring Mode to Determine its Value ,if it’s Damaged u have to replace it. but before that, u have to check Transistor Q3 , it’s a 6 pins transistor , for measuring this transistor u may adjust ur multimeter to Diode Mode,[ the right Value will be: (first two pins = 0.000 , second two pins =0.000 , Third two pins = nearly over 600)]
    if Q3 is Damaged it will burn ur R120 after u replace it , so be sure that Q3 is ok before replacing R120 & u may also Check Transistor Q6 by the previous method to be completely sure it’s safe to replace R120.
    Note: ( to be sure of The right values of these electronic components u may compare the values u have measured with the values of a working PCB’s Components)
  3. Check The Coils (such as L2 & L7) – adjust ur multimeter to diode mode then the right value must be ( 0.000 ) for any coil as u all know.
  4. inspect the whole PCB for any removed component ( such as small capacitors or Resistors ) … the removal of these small components may occured while forced cleaning of the PCB …. so becareful while cleaning it.
  5. in rare cases the firmware microchip may be damaged.

2- The Continuous Noise

sometimes there is a continuous noise come from WD HDDs mainly with L-shape PCBs
with motor ICs ( Smooth 1.3) , (L6278 1.7) & (L6278 1.2).
the noise is like : Trrrrrrrrrrrrrr or Trrrr….Trrrr…Trrrrr

so all we have to do for fixing this problem is:

  1. 1- clean the connection points which connect the head stack pins with the PCB using a pencil Rubber …carefully.
  2. 2- clean the motor IC pins thoroughly using a solvent & Toothbrush then wipe it with a piece of smooth handkerchief to remove the dust & dirt from it.
    -Note- the two steps mentioned above solve the problem in few cases.
  3. 3- if the two steps mentioned above didn’t fix the problem , you have to replace the motor IC cause it’s damaged.

Note: in case of Motor ICs (L6278 1.7) & (L6278 1.2) first try to desolder them then resolder them again before u decide to replace them with a new ones … this sometimes work , but if it didn’t work … replace them directly.

In case of Motor IC (Smooth 1.3) you must replace it directly. Image below Shows you where to clean.

Western Digital 2.5″ Laptop PCB Buying Guide

July 16th, 2012 Comments off

As we know:  Western Digital 2.5” Laptop HDD can’t spin; board/chip be burnt; interface broken; etc. These problems are caused by PCB malfunction. Swap PCB of your Western Digital 2.5” Laptop hard drives can resolve the problems.

1. Western Digital 2.5” Laptop Hard Drives PCB Buying Guide:

For Western Digital 2.5” Laptop HDD, just need the donor PCB has the same board number as yours.

western-digital-hard-drive-pcb-swap

2. Before Western Digital 2.5” Laptop PCB Swap you should know:

1. Most PCB’s BIOS chip(ROM Chip) store the unique information. We need change the BIOS form original PCB to replacement PCB, in order to make the replacement PCB compatible with the HDD.  The 8pins (4 pins on each sides) with 25P05VP、25P10VP、25F512、25F1024、25F1024AN、SST25VF512、SST25VF010, etc. are the BIOS Chip.

Tips: Most of the TV/Phone Repair Shop can offer these services for just $5-%20

2. Some PCB don’t have separate BIOS. The BIOS be integrated on the Main Controller IC(The biggest chip on the board, also named Main Chip). We should exchange the Main Controller IC to let the HDD be recognized.
