Your worst nightmare
just became a horrifying reality. You keep hearing that little voice
in your head mockingly shout “you should have backed that stuff
up” The voice keeps echoing throughout your head as you perform
a quick inventory all of the important information that you just
lost…..your client database, a years worth of e-mail, your entire
inventory database, even your family photos.
|
Even worse, you’ve
got a deposition in two-weeks and key information needed to help win
the case were also lost. You quickly call a service technician and
have them come over to check the computer out, only to hear the
worst news of all….your data has been lost. When a hard drive
crashes, it’s too late to worry about what you “should have
done.”
What is hard drive data recovery:
Today data recovery is a multi-million dollar
industry. The number of data recovery firms out there seems to
exceed the number of fast food restaurants for the entire planet.
These companies specialize in helping their clients retrieve data on
anything from hard drives to flash-roms.
In the following
report, we will discuss what data recovery really is; the different
types, the costs, and what you can realistically expect when it
comes to getting your hard drive data recovered.
What To Do In The Event Of Data Loss?
Around 44% of all data loss is caused by hardware failure.
It’s important to make sure that you immediately shut your system
down if you suspect that hard drive has crashed. Don’t even try to
go through the shutdown procedure, just pull the plug from the wall.
Do not try to run off the shelf data recovery software or drive
utilities.
Many times these
applications will assume the drive is functioning properly and will
increase the risk of permanent data loss.
Types Of Hard Drive Failure.
When we discuss
hard drive data recovery in this report, we will primarily focus
on issues surrounding hard drive failures; since these types of
failures are most common. There are really two primary forms of
failure in a hard drive, logical and physical. Logical failures are
usually a result of file-system corruption. This can occur due to a
virus, accidental deletion of key files or registry components, and
in some cases even electro-static discharge. In most cases where a
logical failure has occurred, the drive is still recognized by the
system BIOS, but it will not boot. In most cases, your data should
still be intact on the drive, even though it may appear to be
inaccessible.
If the system BIOS does not detect the presence of the hard drive,
then chances are a physical failure has occurred. Physical failures
can result from a wide variety of causes. There are really two
sub-categories for physical hard drive failures; mechanical and
electronic. Mechanical failures usually result from a failure of the
spindle motor. Spindle motor failure can result from excessive heat
due to a bearing failure. The increased heat resulting from the
bearing failure will expand the drive shaft and therefore seize the
spindle motor. Suddenly, your drive will become inoperative.
Occasionally, you will get a warning that something bad is about to
happen. You may hear a loud whining, a grinding noise, even
high-pitched screeches. If anything like this starts to occur,
BACK UP YOUR DATA IMMEDIATELY.
Another physical issue that sometimes rears its ugly head is an
electronic failure. If you look at a hard drive you will notice a
circuit board on the bottom. This board is basically the brains of
the drive, and it is where the computer interfaces to the hard
drive. An electrical failure can occur unexpectedly at any time.
Even brand new hard drives are not totally immune to having
electrical failures. Sometimes it’s just a faulty component,
sometimes it’s improper installation (i.e. electro-static discharge,
grounding out the board, damaging circuitry during installation).
It’s important to also keep your system clean and well ventilated,
since excessive heat can damage the electrical components on the
drive. If you have a system that is in a somewhat contained area,
you may look at adding an additional 80mm fan to cool the internal
components of the system, especially the hard drive. No other
component of a computer works as much as the hard drive, and
therefore it is vitally important not to overlook it when cooling
issues arise. A simple step like this can help against needing hard
drive data recovery services...
How Is My Hard Drive Data Recovered?
One of the most often asked questions that customers ask is, “how do
you get my data back?” Well, it’s really not black magic or rocket
science. It’s just a matter of having the right tools and the
knowledge necessary to know what to do, much like a surgeon
performing heart by-pass surgery. Many prominent data recovery
facilities have a large array of hardware, software and tools for
recovering data.
Generally speaking when a hard drive is received by a data recovery
firm, the first thing they do is evaluate it, and determine what
recovery solution will be necessary. If the drive failure is a
logical issue as mentioned earlier, then a scan of the drive will be
performed to try and repair the file system corruption. Sometimes a
partition can be repaired and the drive restored to the status that
it was before the failure. If this is not possible, then a very
low-level scan will be performed that essentially searches every
sector of the hard drive for files. Once the files are located, they
can then be copied to the media of choice, i.e. a CD-ROM, DVD-ROM or
another hard drive. Logical recoveries can take up an enormous
amount of time, especially if the drive is on the verge of physical
failure. It’s not uncommon to allow for one day of scanning and a
day for recovering the found files.
If the drive has suffered a physical failure, then the recovery
procedure is quite a bit more challenging. As mentioned above, there
are really two sub-categories of physical failure; mechanical and
electronic. An important element in recovering data from a physical
failure is having the necessary parts to get the drive functioning
again. Unfortunately with hard drives if you have a 20GB Maxtor Hard
Drive for example, then you will need another identical 20GB Maxtor
Hard Drive for salvaging parts. In cases where the electronic
circuit board has failed on the hard drive, then you have to have
the exact same circuit board on hand in order to retrieve the
necessary circuit components for replacement. Many times you cannot
even exchange circuit board for circuit board. These repairs
generally require soldering skills and a thorough knowledge of
electronics to be successfully completed. You will most likely hear
“Class100 Clean Room” thrown around a lot when talking to
data recovery professionals. Simply stated, a Class100 Clean Room
maintains exceptional air purity, and contains less than 100
airborne particles larger than 0.5 microns in each cubic foot of
air. This is vital in protecting sensitive internal components of
hard drives. Anytime a hard drive is having an invasive procedure
performed on it, a Class100 clean room or better is needed.
The time frame for recovery is generally 5-10 business days for
physical issues and 2-4 days for logical issues. Sometimes if
components are not readily available, then it may take weeks to
complete the recovery. Some firms offer expedite service and you
definitely pay for this added attention.
What About Hard Drive Data Recovery Software
This is one area where you really do get what you pay for. Try to
stay away from software in the $20-$60 range, since these utilities
are generally very limited in what they can do. Also make sure that
you NEVER and just to emphasize, NEVER EVER get data
recovery software that writes anything at all to the damaged disk.
You run the risk of overwriting data that may otherwise have been
recoverable, but will be lost forever. If you are fairly computer
savvy, then there are a few good data recovery software solutions
available.
What To Look For When Shopping For Data Recovery
There’s an old saying, “you get what you pay for.” In most cases
this is true. However, just because a company with a fancy website
quotes you $3,500 for data recovery, does not mean that they are any
better than a company that quotes you $1,500. Also, try to stay away
from companies that want to charge $50-$300 for evaluating your
drive. There has been a movement in the data recovery industry over
the last couple of years to offer a number of free services. Most
reputable data recovery companies will evaluate standard IDE drives
free of charge; so don’t let the word “free” this or “free” that
stop you. The hard drive data recovery market is quickly becoming
saturated, and a company does not necessarily cheapen itself or lack
expertise by offering free evaluations.
You will find as you shop around for data recovery that prices vary
greatly. You will get quotes that range from $300 to $5,000 for
standard hard drive recoveries. It’s not uncommon to literally get
quotes that have at least a $1,500 high/low spread. We shopped one
prominent data recovery company where we gave them specific
indicators of a physical hard drive failure. We were eventually
quoted a price range of $600 to $2,900 for the recovery. Many times
this is a bait and switch type tactic. They get you to send in the
drive with the low-end $600 price, then they let you know it’s going
to cost $2,100 for the recovery. You end up being well under the
$2,900 high-end price, but well over what other reputable companies
would charge. Since most customers won’t go through the pain of
having the drive sent back, only to have to send it out to another
company, these bait and switch companies end up making huge profits
off of unsuspecting customers.
Try to find a company that will give you an up front cost for either
a logical or physical recovery. Most companies will be able to tell
you within a couple hundred dollars the cost of a recovery. However,
don’t misunderstand a company that gives you a price for two
different procedures. For example, some companies will give you a
price if the failure is logical and a price if the problem ends up
being physical. We called one firm and were told that if the drive
had a logical failure the price would be $400 and if it ended up
being a physical issue the price would be $1,600. This is not a
high/low spread as mentioned in the earlier example, this is simply
quoting a price for two different types of recoveries.
On average you can expect to pay anywhere from $400 to $600 for
logical recoveries, and $1,200 to $2,000 for physical recoveries on
standard IDE hard drives. If you have RAID drives, SCSI, etc.
depending on the configuration prices can be as high as $15,000.
Remember, backup
backup backup backup backup!!
Can My Data Be Recovered?
In most cases the answer to this question is yes. On average, the
success rate for data recovery professionals is about 75-85%.
However, there are times when the data is just lost, either due to
extensive damage to the platter or unavailability of replacement
parts.
How Do I Get Started?
If you have a hard drive that has crashed, the most important thing
you can do is contact a data recovery professional immediately. Make
sure you aren’t being charged an evaluation fee if you have a
standard IDE hard drive. Most companies only charge evaluation fees
for complex RAID and network server drives.
You will find links to various data recovery firms on this page. We
do not support or endorse any of them, but they are listed for your
convenience. It is important to do your homework, call and talk with
the companies. When you find one that you feel comfortable with,
give them a chance. Your hardest job, may be finding data recovery
firms that actually have someone available to answer the phones. Ask
questions and be sure to have the following information available:
-Size of the drive
-Operating system (i.e. Windows 98, Windows XP, etc.)
-Situation of failure (what happened just before the drive stopped
working)
-Is the drive recognized by the computer's BIOS or not
Good luck in getting
your hard drive data recovered, and make sure you always backup your
important information on a daily basis. For more information visit:
