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