Abstract: A first entropy indicator is calculated at a first time for a collection of data stored in at least one memory. A second entropy indicator is calculated at a second time for the collection of data. The first entropy indicator is compared with the second entropy indicator. Based on the comparison, it is determined whether to back up the collection of data and/or whether to retain an earlier backup of the collection of data.

Abstract: A Data Storage Device (DSD) or a server is set to an unlocked state to allow access to a memory of the DSD or to a DSD of the server. Communication is established with an access station using a wireless communication interface, and an access code is received from the access station via the wireless communication interface. If the received access code is determined to be valid, the DSD or server is set to the unlocked state. According to another aspect, communication is established with a DSD or a server using a wireless communication interface, and an access code is generated and sent to the DSD or the server for setting the DSD or the server to the unlocked state.

Abstract: Certain apparatuses, systems, methods, and computer program products are used for multi-plane memory management. An apparatus includes a failure detection circuit that detects a failure of a storage element during an operation. An apparatus includes a test circuit that performs a test on a storage element. An apparatus includes a recycle circuit that enables a portion of a storage element for use in operations in response to the portion of the storage element passing a test.
