two surfaces of the latching mechanism together and rotate the handle of
the disk unit towards you. Pull the disk unit partially out of the tower.
Attention: If you remove the device when the light is not flashing, data
may be lost, the disk unit may be damaged, or the backplane may be
damaged.
Note: The light above the device location will go off and remain off as soon
as the device is no longer making contact with the backplane.
Wait another 5 seconds to allow time for the disk to stop spinning. Then
pull the disk unit the remaining way out of the tower.
