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, drive reliability may be compromised
and could lead to permanent damage--doing so voids the warranty.
