Data recovery should be done using a cleanroom technology, and companies that specialize in hard drives and data recovery should use cleanroom services for a number of different reasons. When a hard drive is opened in order to begin data recovery, it is then exposed to a number of different dust particles. These dust particles can then further corrupt the files or cause damage to the hard drive. If a hard drive is already damaged, doing data recovery in the cleanroom might give it a better chance of recovering the needed data.
When a data recovery company is using cleanroom services, the environment is free from any airborne particles. The area is restricted and employees must have specialized gowns and coverings, caps or hoods need to be worn, doors are closed as much as possible, and there is a double-door entryway in place. Many cleanrooms will need to come with HEPA filters, in order to remove dust particles that could cause problems with the hard drives. Data recovery that uses cleanroom technology is very specialized, because the cleanroom conditions are not easy to meet.
Due to these very specific requirements, there is a much higher chance of success for data recovery. A cleanroom is one of the safest places for a hard drive. With the best atmosphere achieved, using a cleanroom gives companies the ideal working conditions for data recovery.
There are certain cleanroom measures that make data recovery much more efficient. Not every data recovery process needs to be completed in a cleanroom, but in instances where the hard drive’s cover needs to be removed and can be exposed to plenty of dust and other particles, cleanroom technology should be used. A hard drive platter can rotate several thousand times per minute, which can stir up a lot of dust. With the dust, there can be a lot of damage done to the hard drive and the files can’t be recovered.
Federal standards regulate the control levels in a cleanroom, so in order to qualify as one experts use particle size. Experts will look at particles that are bigger than half a micrometer per cubic foot. The standard cleanroom for the data recovery industry is one with a Class 100 ISO 5 rating. A Class 100 ISO 5 rating will only allow for 100 particles for every cubic foot, leaving very few to damage a hard drive and corrupt files.
There are other benefits to cleanrooms for data recovery. Not only are there less dust particles in cleanrooms, but companies can also control temperature and humidity in order to further protect hard drives. Since cleanrooms have restricted entry guidelines, data would be secured in these instances.
