behavior and consistency are dependent upon certain factors. These
factors are broadly divided into software factors, hardware factors and
the surroundings.
The common software factors leading to a logical failure are:
i.) System files responsible for handling control to the operating system missing or corrupt
ii.) Unsigned drivers or drivers trying to access read only system area
iii.) Operating system files corruption due to incomplete automatic update, malicious software
The common hardware factors leading to a physical failure are:
i.)
Problems related to mainboard in terms of the chipset or connector,
power supply issue like incompetent power supply to run the hardware
setup
ii.) Problems related to
hard drive itself or the data or power cables
iii.) Improper setup of hard drive cooler fans (if any)
The common surrounding factors leading to data loss are:
i.) Heat dissipation issues related to closed or poorly ventilated surroundings like in a basement or store
ii.) Moist surroundings leading to the formation of thick dust layers and thus increasing heat
iii.) Direct sunlight leading to extra heat and thus hardware failure
We
should logically negate these scenarios so that we can narrow down to
the root cause of the problem and take corrective measures.
In case we find that the data loss is due to any logical failure, we can use
data recovery
software as they are programmed to meet the challenges due to all kind
of logical crashes. They scan through the file system, locate all the
files which are marked as deleted and are distributed as fragments
across the partition, logically rearrange them as per the file system
information and then recover them. The data recovery software are
indispensable in cases like file system corruption, hard drive
formatting operating
system corruption, accidental file deletion
or malicious software like virus, spyware etc. We can perform a ‘Do It
Yourself’ data recovery using these utilities as they are self
descriptive and User friendly.
We need to install the data
recovery software on another hard drive which is bootable. We can also
use a different working system preferably using the same operating
system platform as for MS Windows. Then, we can attach our hard drive
to the same for scanning. For attaching the hard drive we nowadays use
USB 2.0 Hi Speed or IEEE 1394/Firewire Cables, Attachments or
Enclosures. The same can be achieved by a Master and Slave setup that
requires hard drive jumper operations and thus is a little complex. We
should avoid any other jumper operations as of the mainboard as they
may lead to unstable system behavior based on BIOS settings.
We should always save the recovered data on a healthy hard drive.
In
case of data loss due to hardware failure where the hard drive is
either not getting powered or can not be recognized by the BIOS, we
need to go for hard drive recovery service. The data recovery service
is personalized help, delivered by data recovery experts. Such experts
can extract your data in all possible scenarios of physical data loss.
