Computer Data
Recovery
If you're seriously interested in knowing about
computer data recovery, you need to think beyond the basics. This
informative article takes a closer look at things you need to know
about computer data recovery.
Ever wonder how computer data is recovered? What happens to a file
when it gets deleted from the recycle bin? How data recovery
programs work? How does computer data recovery take place?
To understand how computer data recovery happens we must first
understand what happens when a data file is deleted. Does a file get
completely wiped out of the PC once it’s deleted? The answer is –
no. First of all a file once deleted just changes addresses and goes
in to the recycle bin. The real deletion takes place when it’s
deleted from the recycle bin as well. Then the question arises –
what happens to the file? Well. The file is right there inside the
PC, hiding in the hard disk.
The illusion within the virtual world gives us a false picture of
how files are actually stored in the disks. The partitions and the
drives that we see on our Windows are not arranged that way in
reality. The disk stores files in clusters unlike the way it’s
displayed on the monitor.
If you find yourself confused by what you've read to this point,
don't despair. Everything should be crystal clear by the time you
finish.
The Operating System knows what file is stored where. When a file is
deleted, the Operating System, like a robot, just removes the file
from its list without actually removing it from the hard disk. FAT
(File Allocation Table) and MFT (Master File Table) are like
contents in a book, which actually maintain the real table of all
files stored on the hard disk. So, even if a file is removed from
the Operating System its still there on the hard disk and can be
searched by looking up at FAT or MFT.
Computer data recovery involves a few simple steps to recover data.
The first step is to determine what type of recovery is required.
Accordingly, suitable data recovery program software is installed or
run. The search can be confined to a folder or drive. The entire
disk can also be scanned. The file type has to be selected to make
the search more efficient and quicker. Once these details are fed to
the data recovery program it’s only a matter of time that the
target, the lost data, pops up along with other lost data. From a
list of such files one has to select the target file for which the
search was intended and recover it.
The only care that one has to take when data is lost is to avoid
adding a new data file to the hard disk. This might really erase the
data by over writing it.

This article's coverage of the information is as complete as it can
be today. But you should always leave open the possibility that
future research could uncover new facts.
