Recovery of Personal Computer Data

Unless you're rather computer savvy, you probably believe that the data on your computer - such as a word processing document - is completely eradicated once it's been deleted or lost through some other means. This is really quite far from the truth. The recovery of lost data is possible, if you're equipped with the means and the knowledge to do so.

In the workforce, the system administrator is typically responsible for data recovery, and - depending upon company policy - will often perform the recovery and make the data available to you within the hour of the request. For those who are faced with data recovery on their home computer, however, all is not lost. Virtually all information is obtainable until it has been over-written by new data.

The principle is quite simple: when - for example - a word processing document is deleted, a copy of it still exists within a designated area of your computer's memory. As other data items are deleted, they continue to take up portions of the memory space. Eventually, the free space in that particular area is taken up and newly deleted data simply over-writes - or takes the place of - what had previously occupied that space. Recovery can be performed for those bits of data that have not been over-written.

Data recovery is often performed by government and law enforcement officials, in an effort to obtain evidence of a crime. While these agencies may have more advanced tools which can be utilized for the recovery of lost data, even basic home computers offer this function, provided the user is armed with the necessary knowledge to perform the task.
