All Maxtor hard drives are assembled in a Class 100 controlled environment. Over
the life of the drive, a 0.1 micron filter and breather filter located within the sealed
head disk assembly (HDA) maintain a clean environment to the heads and disks.
Maxtor drives are designed to operate in a typical office environment with
minimum environmental control.
