Specialist data recovery firms will work in climate controlled environs with extremely low levels of floating particles in the air, such as Class 100 Clean Rooms meeting specified standards. This is important because if devices like a hard disk are opened in ordinary environs, the minute dust particles in the air can settle on the disk platters and lead to serious problems for the read/write heads.
