As more and more data gets stored on storage media increasing the risk of data loss – the opportunities of data recovery seem infinite. One of the most important aspects in the data recovery process is that of the Clean Room. Basically a corrupted media is taken to the clean room once data loss has been evaluated and a price quote has been given. A Data Recovery clean room can be defined as an environmentally controlled space free of contaminants such as dust or bacteria.
In technical jargon, one can state that clean room technology holds a key position in the data recovery field. The absence of clean room technology can actually corrupt and damage the storage medium leading to more devastating data loss that it originally had experienced. In order to understand the function and importance of a clean room in a data recovery lab – one needs to know the inner structure and working of that particular storage medium. A hard drive is a typical popular storage medium used by huge corporations and billions of personal users. Hard drive data loss can be easily recovered through clean room technology. Basically, a hard drive is a fragile magnetic storage medium. The inside of a hard drive consists of one or more heads which read and write information to the platters of the drive. These platters are magnetic in nature and are extremely sensitive -- physically and magnetically – to any external pollutant or environmental factor. Opening a drive in an unsafe environment can expose the magnetic disk structuring to pollutants contaminating the disk platters. Dust, microscopic bacteria including heat particles possess the ability to wilfully damage the disk. In short, even a small pollutant can cause irreversible data damage. Thus, for the success of data recovery, it is crucial to open the drive in a controlled, pollutant-free environment. Pollutants in most cases come from air, heat, light and human errors. They usually include humidity, movement, dust, microscopic bacteria and human hair.
Even though the pollutant may have corrupted only one section of the disk, the entire disk is prone to data damage as pollutants such as dust and bacterial particles have the ability to spread rapidly destroying entire chunks of data. This means that a clean room can be deemed unfit if cleaned and dusted by hand. The room is cleaned free of any sort of pollutants with the aid of powerful air filters. Usually data recovery companies use and maintain a Class 100 Clean Room for portable and optical storage data recovery of tape drives. A class 100 clean room is one which has less than a one hundred microscopic contaminants per square foot of space. Clean room technology is always changing for implementation and usage of better and more technically advanced cleaning procedures. The level of clean room technology is usually gauged by the amount of air cleanliness available inside the room. In addition to controlling temperature including heat, light and bacteria level, one has to look into the aspect of human contamination of the disk. Engineers and technicians are advised to wear high-tech protective suits with masks and gloves to reduce the risk of data corruption by human breathing, human sweat and hair. In other words, the main objective of a clean room is the generation of pure and uncontaminated air through the constant removal of pollutants through humans, machinery, equipment and processes.
Clean rooms were first established in the 1960s to fabricate precision technology in various research and manufacturing industries. But, by early 1980s, clean room technology began to be used in data recovery processes in manufacturing industries. Today, clean room technology is used commonly in various data recovery companies such as Ontrack, Disklabs and Vogon International. Clean rooms have become an integral part of the process of recovering data as these rooms enable engineers to separate the exact cause of the data loss and restore saved data on another disk. The available clean room technology is able to detect microscopic contaminants and retrieve data in its original format as quickly as possible.
A clean room can be as small as an office cubicle or as large as a football field. It can either be permanent, modular or portable with hard/ soft walls. The sanitised, septic-clean environment of the clean room uses layers of specialised air filters and cleaners of HEPA i.e. High Efficiency Particulate Air Filters, air showers, air locks, directed air flow called laminar flow with regular cleaning and upkeep operations. Some companies such as Aero Data Recovery have introduced the concept of Clean-Flow Benches which are used as an additional wall of security against air pollution in the clean room.
