Hard Disk Drive Breather Holes

Hard drives used in the OmniBook 800 have a breather hole located on the metal side of the drive (see Figure 26 for location of breather holes for both IBMâ and Toshiba). The hole is necessary to provide pressure equilibrium. The breather holes must not be obstructed. Any labels covering this breather hole must be removed to prevent data loss on the hard drive.

Just below the metal surface of the drive, a white material can be seen through the breather hole. This is a filter and should not be disturbed. A drive with this filter damaged should be considered defective.
