Data recovery relates to the many ways to extract data
from a inaccessible or otherwise damaged magnetic medium. Technology varies widely,
and there are no set standards as of yet for this type of service. The demand
for emergency data recovery is rising steadily and throughout time numerous devices
have been created that have aided the data recovery process.
The origins of data recovery can be traced back to the discoveries
of Charles Babbage and Ada Lovelace. In 1833, Babbage started working on
the creation of the first computer. This invention, which was later known
as the Analytical Engine, was based on the components of the modern computer
we use today. Babbage worked on plans for the engine for eleven years until
he reported his developments at a seminar in Italy in 1841. An Italian named
Menabrea wrote a summary of this seminar and published the article in French.
In 1843, Ada Lovelace translated Menabrea's article and suggested to Babbage
that she add her own notes. These notes turned out to be 3 times the length
of the original article, and Ada and Babbage combined ideas to finish creating
the Analytical Engine. Programs for the engine were punched on Jacquard
cards; as a result the machine was known as the "punch card system." However,
eventually Babbage and Lovelace ran into a problem: one of the punch cards
was damaged extensively by Babbage in the handling process. Retrieving the
lost data from the corrupted punch card turned out to be an extremely difficult
task, one in fact that neither Babbage nor Lovelace could do. A more advanced
data storage system was needed in order to correctly retrieve lost information.
This was the first known instance of the need for data recovery technology.
Over the years since the Analytical Engine was developed, the computer
field (and consequently the data recovery field) has developed at an overwhelmingly
rapid pace. As a result, the demand for new data recovery services has
advanced at the same rate. An extensive array of new ideas and concepts
have surfaced as technology has advanced. One of the major accomplishments
in the computer field was the ENIAC in the 1940's.
The ENIAC (Electrical
Numerical Integrator and Computer) was the first multipurpose computer.
Within the next decade computers began to be used commercially, largely
due to the incredible accomplishments of the ENIAC. Not only were multipurpose
computers able to store more information, but with the invention of the
ENIAC, computer use became more common. Consequently, there was more room
to store data and more people were using computers to store information.
Another major advance in the industry was IBM's first magnetic tape drive
vacuum column for data storage in 1952. This discovery further increased
storage and processing capabilities of the computer. Before the column was
introduced, weak magnetic tape was used to store data. The fragile magnetic
tape was a reasonable means for storage but the frequency of breakage and
sudden starts and stops was high. With the IBM vacuum column, the tape was
held down by a vacuum during movement. The decrease in breakage resulted
in a less occurrence of data loss and made data easier to retrieve when
there was a problem. In 1962, the Logic probe was introduced. The Logic
probe is used on electronic logic circuits to look into failed chips. While
the Logic probe only indicates state changes, it helps to identify the basic
reason a chip may be failing.
In recent years, hard disk data recovery
has continued to become a vital industry as computers become increasingly
important in our everyday lives. The data recovery
specialists at ESS are on the forefront of this rapidly changing field
and is dedicated to retrieving the data important to you.
