Western Digital Hard Drive Families (Part I)

DATARECOVERYUNION.COM05 mins

Western Digital Hard Drive FamiliesWestern Digital Corporation (often abbreviated to WD) is the second largest computer hard disk drives manufacturer in the world, after Seagate and has a long history in the electronics industry as an integrated circuit maker and a storage products company. Western Digital was founded on April 23, 1970 by Alvin B. Phillips, a Motorola employee, as General Digital, initially (and briefly) a manufacturer of MOS test equipment. It rapidly became a speciality semiconductor maker, with start-up capital provided by several individual investors and industrial giant Emerson Electric Company.

Noise related to PCB in WD HDDs (Part II)

DATARECOVERYUNION.COM02 mins

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) – clean the connection points which connect the head stack pins with the PCB using a pencil Rubber …carefully.

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) – 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.

Noise related to PCB in WD HDDs (Part I)

DATARECOVERYUNION.COM03 mins

Now discuss the Causes & Solutions of Two Main types of Noise which is occurred in WD HDDs (Especially Related To L-shape PCBs).

Clicking Noise and Continuous Noise:

1- The Clicking Noise
when you 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 & Toothbrush 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)], you may adjust your multimeter to Resistor Measuring Mode to determine its Value, if its damaged you have to replace it. but before that, you have to check Transistor Q3 , it’s a 6 pins transistor , for measuring this transistor you may adjust your 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 your 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 occurred while forced cleaning of the PCB…. so be careful while cleaning it.

5) – in rare cases the firmware microchip may be damaged.
