The identified deviation may be analyzed for further information in a message. The message may be used to recover from the deviation.

Abstract: A drive (e.g., hard drive) carrier can have a frame with a door that can open to permit installation of the drive and can snap shut to secure the drive within the drive carrier. The drive carrier can include a connector lock, which can take the form of a pair of pins extending from the frame and capable of engaging corresponding retention holes of a connector of a cable. The connector lock can help align the cable's connector with the drive's connector, as well as releasably lock the cable's connector in place when operatively connected to the drive. Damping couplings can couple the carrier frame to a computer chassis. The damping couplings and the flexibility of the cable vibrationally isolate the drive from the chassis, while the connector lock ensures the cable's connector does not unintentionally disconnect from the drive.
