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.

Clean rooms are used extensively in the pharmaceutical, semiconductor manufacturing and biotech industries. Data recovery centres typically use a Class 100 clean room that has an allowance of 100,000 particles per cubic meter (compared to 35 million particles per cubic meter in a normal room).

Why Are Clean Rooms Essential For Hard Drive Repair?

Clean rooms are used for data recovery to prevent dust, electro static discharges and such disturbances. These kinds of precautions become necessary because even microscopic dust particles can damage the image on the drive platters, and make data recovery difficult.

With each generation of disks, data is packed more and more densely on the disk platters. It is thus increasingly important that data recovery be attempted in exceptionally clean rooms.

Another consideration for using a clean room though is the warranty on your drive that will be made invalid if not repaired by an authorised agent or in a clean room environment although in reality the value of the accumulated data on most drives is by far massively more valuable than the drive itself, so all the more reason to ensure that it is only worked on in the cleanest of environments to prevent further damage.

So in summary clean rooms are essential for maximising the chances of a successful data recovery from a failed drive, are necessary for warranty considerations and perhaps most important of all to protect the integrity of any data on the drive because in many cases if the data is not backed up once lost it is gone forever, the loss of which can be devastating for both individuals and businesses alike.

If you need to hand over your hard drive to a data recovery services company check the validation of their clean room. At the very least it should be class 100 certified although the top companies will have invested in even better standards, for example ISO class 3.
