Data is undoubtedly vital to both companies
and individuals throughout the world. Technology has
grown in leaps and bounds throughout the years and storage
media has grown with it. With the ever growing storage
demands, manufacturers now offer hard disk drives which
are now faster and larger than ever before. What many
consumers do not realize is that storage media has always
been a fragile science with precision being a key element
in it’s functionality. Precision and fragility
brings susceptibility to many elements of danger. We
believe there are 3 main trends in Data Loss and computer data recovery today –
manufacturers pushing the limits of hard drive capacities
& speeds, more critical company data placed within
disk drives, and faulty implementation of back-up
As touched on earlier, there is now more data being
stored in smaller spaces. A decade ago, hard drive storage
capacity was approximately 40 megabytes. In today’s
market, many hard drives store up to 120 gigabytes (GB)
within an even smaller media device – i.e. a 2.5”
laptop drive. With this amount of data stored within
such dense areas, mechanical precision is crucial to
The sensitivity of hard drives, also known as drive
tolerance, has always been incredibly small. The distance
between the read/write heads and the media platter is
so miniscule, any trauma such as an accidental drop
or a sudden shake may cause the head to make contact
with the platter resulting in physical damage to the
media. Currently most drives are designed with the read/write
heads 1-2 micro-inches from the platter. To put this
in perspective, a speck of dust is 4-8 micro-inches
and a piece of human hair is 10 micro-inches.
In today’s fast pace world, users find themselves
placing irreplaceable data ( i.e., company records,
accounting records, bank files, payroll records, sales
transactions, master’s thesis, etc) onto their
desktops, laptops and networks. When these crucial
documents become lost, companies may lose thousands
if not millions of dollars and some may even go bankrupt.
Drive recovery has never been more important in this
Most companies utilize backups and redundant storage
technologies as their safety net to protect themselves
from data loss. Backing up has always been and will
continue to be a company’s best defense against
data loss. Although this is the best option, backup
technology and procedures are not always full proof.
Failure may come when procedures are not implemented
properly by the administrator, system hardware is not
functioning correctly, software may become corrupted,
and tape/cartridge media may not be in working order.
Backup systems rely on perfect harmony between human,
mechanical hardware, and software to work as intended.
All too often, it is those crucial moments when data
loss strikes, that backups find themselves useless.
With increasing storage capacities coupled with decreasing
physical sizes of hard drives, manufacturers are storing
more information in smaller spaces than ever before.
Because of this, the question must be raised –
are we pushing the envelope faster than we should? Are
manufacturers risking reliability/MTBF (Mean Time Before
Failure) in place of performance and more sales?
With such an amount of mission critical data stored
within these delicate mechanical storage devices, most
people never truly consider what a huge impact a drive
crash can make on their lives until this traumatic experience
actually happens. Personal computers and laptops are
storing more data than ever before and this trend is
not slowing down any time soon. Data loss for most companies
are not a mere inconvenience, but instead a huge financial
liability and risk.
Below, you can see some percentage breakdowns for data
loss. We have found that in most cases, there are two
main reasons for computer data loss, data recovery services
and hard disk data recovery – hardware/system failure
& human error.
& System Problems
crashes, electrical outages or power surges,
deletions, overwriting files, causing trauma
to desktop or laptop.
Corruption or Application Error
displays an error message when a document is
opened. Installing or removing a program corrupts
Through our research and experience, we have compiled
a list of computer data recovery issues we’ve come across
most often. We hope that this information will assist
people in their awareness of data recovery services
and to educate themselves in the prevention of a data
Extensive physical damage is caused when the read/write
heads of a hard drive come into physical contact with
the media surface.
Unusual noise omitting from the hard drive – clicking,
grinding or scraping.
What to do:
At any time, if any unusual sounds are heard, SHUT DOWN
THE COMPUTER IMMEDIATELY! Permanent data loss may occur
if left running.
We consider this to be the most common natural occurrence/disaster.
Power surges may occur with common power outages
or lightning storms. Extreme power fluctuations
may severely damage media electronics and directly
effect a drive’s
read/write heads resulting in physical media damage
and/or data corruption.
Smoke omitting from computer, sparks, inaccessible data,
drive will not power up
What to do:
In most cases, damage will occur once power is returned
to the media devices.
- Unplug devices following all power outages.
- Utilize a UPS(uninterrupted power supply) or a power
surge protector to protect from future surges.
Water and electronics have never been known to work
well together and there is no exception when it comes
to our computer’s electronic components. A single
spill from a cup of coffee or water can bring your computer
to a screeching halt.
Electronics/hard drive water damage, moist, mold
What to do:
When moisture enters your components:
- Immediately power down computer and keep off.
- Do not attempt to dry your hard drive or electronics;
place in an airtight bag.
Even if a hard drive has dropped into a swimming pool
or has been left in a fiery inferno, IntelliRecovery
Drive Recovery can recover it!
What to do:
- Place charred hard drive within an airtight bag and
give it to the specialists.
There are literally thousands of viruses constantly
attacking computers in this internet age. Always protect
yourself with anti-virus software and never open emails
from unfamiliar users.
Unusual messages from unfamiliar users, computer acting
What to do:
- Utilize anti-virus software to attempt to remove viruses
- Update anti-virus software daily
- Following a virus, data may still remain inaccessible.
Contact IntelliRecovery California Data Recovery Specialists
in such cases.
- Be careful to not use any utilities. They may cause
Accidents happen, especially now that so many people
utilize portable laptops for home and business use.
Physical trauma may occur when we drop these devices
or accidentally run them over with our cars, or…
Unusual noises omitting from hard drive (clicking, grinding,
scraping), physical damage to media, drive will not
spin, not recognized by computer
What to do:
- If any of these indications are present, power down
computer and do not reboot.
Making up a whopping 32% of the computer data recovery
incidences, humans are the second leading cause of
lost data. Our fast paced day to day lives sets us
up for inevitable mistakes.
Accidentally deleting files, accidentally reformatting
drive, partition errors….
What to do:
- Do not run utilities to remedy problem yourself.
- Stop using the hard drive and send it to IntelliRecovery
engineers to correctly remedy the problem.
