Standard hard drives that contain internal spinning platters require a cleanroom—a special static and dust-free environment that allows technicians to access components inside the drive housing. It is not safe to open a hard drive outside of a cleanroom and doing so allows dust particles to enter the mechanism.
Even airborne microscopic particles can cause the drive to malfunction, and the read/write heads will damage the platter surfaces. This reduces the chances for your data to be recovered and makes future attempts by a professional data recovery company difficult to impossible.
