6.2.2.1 Packaging
The drive or option kit must be heat-sealed in a moisture barrier bag with bag supplied by WESTERN DIGITAL.
6.2.2.2 Storage Time
The drive may not remain inoperative for a period of more than one year whether or not the original shipping

6.2.3 Corrosion test
The drive shows no sign of corrosion inside and outside of the hard disk assembly and is functional after being
subjected to seven days at 50°C with 90% relative humidity.
6.2.4 Atmospheric condition
Environments that contain elevated levels of corrosives (e.g., hydrogen sulfide, sulfur oxides, or hydrochloric acid)
should be avoided. Care must be taken to avoid using any compound/material in a way that creates an elevated
level of corrosive materials in the atmosphere surrounding the disk drive. Care must also be taken to avoid use of
any organometallic (e.g., organosilicon, or organotin) compound/material in a way that creates elevated vapor
levels of these compounds/materials in the atmosphere surrounding the disk drive.
