How can I extract data from a hard drive with clicking noises,
assuming I am working in a clean room environment? This question must
be answered in steps. (From start to finish.) What equipment do I
need to repair hard drives with mechanical problems such as clicking
noises? (must have a list of particular equipment and places they can
be purchased)
A correct answer will enable me to repair and extract data from drives
with mechanical failure with a success rate no less then fifty
percent. Another words using the techniques found in the answer I
should be able to recover at least 5 out of ten drives with clicking
noises. |

Can you clarify something for me? When you say extract, do you mean
"read data from the drive using the drive's own interface"? Or are you
open to other approaches such as dissecting the platters from the
drive, and reading the data from them using specialized equipment?
As well, when you say "mechanical problems such as clicking noises",
do you mean that the drives make audible noises but continue to
function, or do you mean that the drives makes noises, and no longer
work as expected? Normally, clicking noises imply something wrong with
the drive head arm, and is a precursor to either a head crash or a
failed arm. In the former case, some data will be lost, recoverable
only with specialized equipment and dissection; in the latter, the
only recourse would be dissection. Often, data can be read off the
failing drive before either situation happens, but there will be times
when there isn't enough prior warning of the failure.

When I say extract data from the drive I mean I don?t Care about the
Hard drive itself. The data can be exported to another drive or any
other media, as long as I get the data back in the same condition as
it was. I also need to know what equipment (hardware) exists that
can perform data recovery. Where I can find it.
90% of the time when a hard drive is making clicking noises it is
not recognized by the system and is unable to read the data. This
noise usually indicates that the head rack assembly has a problem. I
need to know how to extract the data after the drive has failed and is
making clicking noises.
If you can fiend a person who has knowledge and actual experience in
hard drive repair and data recovery, who is willing to share his
knowledge, I will make shore to compensate you for it \Thanks Dave

It sounds like you are looking for both the techniques and the
equipment that a data recovery business would have, companies who
specialize in extracting data sector by sector from broken drives.
Most of these companies use custom, in-house tools and software to
repair the drive electronics, or they use clean-room techniques to
transplant the platters from the failed drive to a working chassis so
that they can low-level extract the data. As a result, these companies
tend to be pretty tight-lipped about how they perform their magic, as
that's their competitive edge.
I will see what I can find out about the tools and techniques they use.

That is Exactly What I need, Knowledge about tools and techniques
data recovery. To help me extract data from a hard drive with
mechanical problems. ( clicking noises)
Remember the correct answer will help me recover no less then 50% of
all drives will hardware problems. The reason I say 50% is because I
have been snooping around in the recovery business and from the
research I have done I know its possible to recover about 70% of all
hardware problems.
Thanks In advance

So far, the few techniques and tools I have found information on do
not seem to come with any assurances of success rate whatsoever
(understandable since it all depends on the skill of the person using
them!). So, I am not satisfied with the probability that this will
lead to an Answer that in turn satisfies you and gives you full value
for the list price. I will keep looking, but I also invite my fellow
Researchers to take a look at this interesting question, and if any of
them feel that they can provide you with an Answer that will delight
you, I hope that they will mention this in a "Request for Question
Clarification".
The importance you place on the recovery rate means that the Answer
must refer to tools and techniques where any practitioner, no matter
how novice or expert, can reasonably expect at least 50% success. I
myself will not post an Answer until this criteria can be met.
