Hard Drive PCB Board Problems If
you've ever installed a hard drive, you may have noticed the
green board on the bottom of the drive, and have probably
made a few educated guesses as to its purpose and use.
The green board is known
as the hard drive's PCB, or Printed Circuit Board, and it's
one of the most complex and intriguing parts of a hard drive.PCB

Please: Evaluate this
site Before attempting any form of self data recovery or hard
drive repair
What is the problem?
Does the hard drive spin?
If so does it click?
Does the armature kick out?
Do the hard drives heads vibrate to initiate?
Is there an odd smell to the drive?
If it doesn't spin do you here a slight or faint ticking sound?
Does the BIOS see the hard drive?
Does the BIOS see the hard drive as the correct model?
Are there funny characters showing on boot?
Does the operating system blue screen?
Important things you should be aware of before you do anything
to a suspected failed hard drive
Static discharge will kill a hard drive when handling... especially
the internal components
Dust will destroy your data... DO NOT OPEN! In my experience
I see so many hard drives destroyed by helpful neighbors when
the problem was not situated internal of the hard drive assembly.
Just because it clicks doesn't always represent an internal
failure.
Swapping the electronics runs the risk of further damage,
especially if the revision number of the PCB is different.
You will have a greater success of data recovery with less
risk if the original electronics is repaired.
Hard Drive Repair
& Data Recovery Information
The Printed Circuit Board
controls many functions to operate the hard disk drive, There
are 5 main features of a the electronics that can be unique
to each drive that is likely to fail, the first being:
POWER INPUT
The most problems we see here are mostly human era... forcing
the power plug in the wrong way
Unfortunately apart from a few notebook PCB's the is no protection
fuse to prevent PCB Damage
There is also risk of power surges making it through to the
electronics as well hard drive recovery/pcb question
--------------------------------------------------------------------------------
Was working on my pc,
which has mirrored 250gb drives. PC Locked up and heard light
clicking. This had happened once before, it was the power
cable loose on the sata drives. I touched the cable, pc remained
locked.... seemed like it powered up for a sec but nothing
happened.
Powered off pc, both drives unrecognized by system. Which
is odd for a mirror, but it must have gotten a power surge.
One of the mirrored drives clicks on boot (not clack-clack-clack
like a crashed head) but more like spin up, click, spin up,
click... like it can't find where to start. the other drive
gets no power at all.
FIRMWARE
Firmware is unique to the PCB this controls calibration and
track information so it is very rare to be able to interchange
the same model PCB with one that has another firmware revision...
so what this means, if your board shorts out the firmware
unique to the drive, you will be in trouble. Of course a good
main stream data recovery company will be able to replace
this and manually reprogram this chip
When hard drives fail,
occasionally it's due to a malfunction of the PCB board. Power
surges can cause this type of a failure, as well as dust contamination
and many other common computer problems.
