CAUTION: Before attempting to remove or install a hot-swappable HDD while the system is

cause an HDD failure.
NOTE: Use only HDDs that have been tested and approved for use with the HDD backplane.
When you format an HDD, allow enough time for the formatting to be completed. Be aware that high-
capacity HDDs can take a number of hours to format.
