USB Drive and Data Failure

Data recovery is a highly specialized science which is
equally valid for rescuing data from both NAND and NOR flash. Although, NOR is
rarely used and is quite expensive, NAND is preferred extensively for mass
storage and a huge godsend for thin and smaller devices.

Globalization is the biggest achievement of human beings in this
era and for upcoming generations. It has changed the entire perception of every
individual relating to human needs and civilizations. A Chinese citizen asking
for a Coke, an African enjoying his lunch at McDonald’s and an American child playing
Japanese video games are all examples of globalization. Thus, no organization
wants to contract its limit over the boundaries of its nation, going global has
become the limit.

We all know globalization is only possible with a strong IT backbone.
Therefore, information should be transferred within seconds, able to be shared simultaneously
around the globe, should be portable and easily accessible. Hence, to meet this
stance in IT, storage devices with lightning fast data transferring have been
introduced.

USB Flash Drives:

A USB flash drive which is also known as a flash drive,
flash stick or thumb drive was commercially introduced by trek technology and
IBM in 2000. These USB drives are composed of NAND flash memory data storage wafers
in devices that are typically of low cost and are easily removable/rewriteable and
weigh less than an ounce, all that with a USB (universal serial bus) interface.

USB flash drives are the new age replacements of older
storage devices like: floppy disks, CD’s and Zip drives which were extremely small,
slow to transfer data and had low storage capacity as compared to flash drives.
A survey made on thumb drives and its uses around the world showed that approximately
88.22 million USB drives were shipped around the globe in the year 2005, in 2006
this increased to 115.7 million. Similarly, Gartner Dataquest statistics shows
that on average there is a 100% rise in the number of USB drives users purchased
worldwide.

USB Data Failure
and Data Recovery:

USB drives have become one of the major sources of data
transferring  sources since 2000. And
along with this, the rate of data failure due to virus attacks and device failures
is also increasing day by day. Many data recovering software products are
available in the market but due to the lack of knowledge and mishandling even a
simple recovery becomes a nightmare for the user.

Data recovery is possible via data recovery software but
knowing the right software for the recovery and using its functions correctly is
very important for a success in recovering the data. Sixty-five percent of data
loss falls under a Tier 1 type recovery process; data loss case can easily be fixed
economically as compared to Tier 2. It is often observed that each case becomes
much more difficult to recover from due to mishandling by end users.

Data recovery handled professionally is the best solution
for any kind of data loss from your pen drive, hard drive, memory stick or any
other storage device. A systematic scan of the damaged device is essential for starting
the right type of action for each attempt at data recovery. Depending on your
file system combination, the drives operating system and document types there
are different ways to handle data loss.

It is always best to consult with expert guidance for
scanning and determining your data loss type and severity because even a minor
mistake can permanently erase your files and data forever.

Data Recovery From Logically Damaged Flash Drives:

Logical damage is usually caused
by virus attacks and power outages. A virus attack on your device corrupts your
stored data and hampers the file system which leads to the absence of data in
your device or problems in showing you the corrupt files. Similarly, power outages
prevent data being completely transferred to your device. Hence, different options
are  used to get these errors under
control. 

In some cases, logical damage is
considered to be the main problem leading to the wrong actions taken which
creates serious data loss. All data recovery operations are carried out in
special labs where humidityFeature Articles, pressure and temperature are maintained.

Data Recovery From Physically Damaged Flash Drives:

Flash drives are fragile and one
of the benefits of its fragileness is its lightweight which makes these drives
handy and portable. But the risk of these drives becoming broken and damaged is
high. 

A physically damaged drive if managed
properly can have a 100% success in data recovery. Recovering data from a
physically injured device requires multiple techniques. Some recoveries include
simple scanning and data reading whereas in other complicated losses a special
disk-imaging procedure is used. Specialized microscopes are often used for
physically injured devices & data recovery.

This procedure is complicated; every
readable bit from the surface needs to be retrieved. Once the data is recovered
all of it is transferred to a safe medium; experts perform different tests to
determine the logical damage on the device if there is any.
