Different people will have different ideas about what a clean room is and why it is actually such an important factor for data recovery. Essentially clean rooms are controlled areas designed to be free from minute airborne contaminants which could be a speck of dust or even pollen for example. Entry to a clean room is gained via an airlock and operators generally use specialist protective garments.

For professional data recovery companies a clean room is an essential asset as hard drive repair often requires the use of exceptionally clean working conditions.

Outside air is filtered to prevent dust entering the room. Filters and processes will be in place inside the room to remove internally generated contaminants during production and working areas are often further filtered locally such as laminar flow bench.

There are different “classes” of clean rooms, with each class limiting permissible different numbers of particles per cubic meter, as well as the maximum sizes particles. Thus a Class 1 clean room is one where the number of particles should not exceed 1000 particles per cubic meter.

The television has been the most used entertainment device in almost all homes in the United States ever since it was invented. It is still number one media source in the home, though the home computer is gaining ground, and it looks like it will stay that way for a long time to come. It has bypassed both newspapers and radio transmission media in terms of use and profitability. But a television relies on a service provider and the two types from which we can choose from are satellite TV or cable television.

Cable TV is transmitted through optical fiber cables and coaxial cables. The major advantage of cable television is that it the quality of its signal is not degraded in any way by mountains, trees or any other geographical limitations. The bad part of things from the cable company perspective is that it is expensive to continually expand and maintain the cabling necessary to broadcast the network content. Today cable television is offered by more companies compared to satellite broadcasting. Such companies are Cox cable, Charter cable, Time Warner, Bright House cable and Comcast cable. The competition to be the biggest and best cable company will ensure you that you will get your money’s worth.

Pen Drive storage devices have proved themselves to be a very practical and robust mobile storage method, far surpassing anything that has gone before. For the most part these devices are very reliable as they rely on solid state technology and therefore have no moving parts, which is a big bonus.

This doesn’t explain the huge number of failures noted in recent months, in fact the whole of the data recovery industry seem to be focusing a lot of attention in the USB Memory Stick Recovery sector, but why should good old trustworthy Flash Memory require such devoted attention?

USB storage devices are also dropping in cost all of the time. They are growing in popularity at such a rate that the number of devices shipped in 2007 was double that shipped in 2006. By the end of 2008, annual sales are estimated to be in the region of 300 million shipped units.
