A mounting for a disk drive unit includes a carrier for carrying a disk drive unit during required movement of the disk drive unit. The carrier defines a space into which the disk drive unit can be inserted, and the carrier is adapted to be inserted with the disk drive unit into a receiving frame for operational use. At lease two resilient devices are mounted on the carrier for securing the disk drive unit in the receiving frame when the carrier is inserted into the frame, at least one resilient device being mounted on each side of the carrier. Each resilient device is movably mounted on the carrier to allow movement of the device as a whole relative to the carrier, and the resilient device is arranged to secure the disk drive unit in the receiving frame by acting between disk drive unit and the receiving frame. A method of handling the disk drive unit comprises placing the disk drive unit into the carrier engaging a robotic device with a coupling structure projecting from the front of the carrier. The method then includes lifting the carrier by the robotic device and inserting the carrier into a receiving frame by a substantially horizontal movement.
