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 IBM 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.

Figure 26 - IBM and Toshiba Hard Drive Breather Holes (respectively)

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.
