Figure 3 Breather filter hole location

Caution: Do not cover, seal, or insert any object into this hole.

This hole has two purposes:

•To allow condensation inside the hard disc to escape

•To allow air pressure inside the hard disc to equalize with ambient pressure

Note. If this hole is covered, sealed, or penetrated by any object, the drive reliability may be compromised and could lead to permanent damage. Covering or sealing this hole voids the warranty.
