Abstract: According to an aspect, there is provided a method for guiding a user of a first computing device in selecting a suitable erasure process for a second computing device. Initially, information on a plurality of erasure reports describing erasure processes carried out for computing devices is maintained in an erasure report database. A remote computing device receives one or more device parameters characterizing the second computing device from the first computing device. The remote computing system compares the one or more device parameters to device parameters maintained in the erasure report database in response to the receiving and based thereon determines one or more expected erasure process properties for at least one erasure process for erasing a memory or part thereof of the second computing device. The remote computing system sends the one or more expected erasure process properties for said at least one erasure process to the first computing device.

Abstract: According to an aspect, there is provided a method for self-diagnosing a mobile device comprising at least one or more actuators, one or more sensors and a display. The method comprises, first, feeding a pre-defined control signal to a first actuator of the mobile device and measuring, in response to the feeding, a first electric signal using a first sensor of the one or more sensors. Then, the first electric signal is compared to one or more reference signals associated with the first actuator and the pre-defined control signal. If the first electric signal fails to match the one or more reference signals according to one or more pre-defined criteria, a negative diagnosis is indicated to a user of the mobile device using one or more of a display of the mobile device and one or more actuators of the mobile device.

Abstract: A method for erasing stored data from the memory of the network device and requesting data from the memory after completion of the data erasure procedure or accessing the memory of the network device after completion of the data erasure procedure. The method further comprises determining the outcome of the data erasure procedure based on: the results of a comparison between a response received from the network device in reply to the request for data and an expected response which is indicative of a successful erasure of the memory of the network device; or the results of a comparison between any contents of the memory of the network device after completion of the data erasure procedure and expected contents of the memory of the network device after completion of the data erasure procedure which are indicative of a successful erasure of the memory of the network device.

Abstract: A method for use in sanitizing a network of non-volatile memory express devices, comprises identifying the configuration of the network of non-volatile memory express devices including identifying one or more controllers of the non-volatile memory express devices; and identifying which portions of non-volatile memory of the non-volatile memory express devices are accessible to which of the identified controllers. The method further comprises performing a data erasure process in relation to at least one portion of the non-volatile memory of at least one of the non-volatile memory express devices based at least in part on the identified configuration of the network.

Abstract: A method for determining a wear value of a battery of a mobile electronic device comprises using historical battery status data to estimate an actual capacity Qact of the battery and using a design capacity Qdes ofthe battery and the estimated actual capacity Qact of the battery to determine the wear value of the battery. A computer program is configured so that, when executed by a processor, the processor implements the method for determining a wear value of a battery of a mobile electronic device.

Abstract: A method of erasing data from a data storage apparatus comprising a memory, the method comprises writing a known data pattern to a plurality of known memory locations of the data storage apparatus, causing the data storage apparatus to perform a data erasure procedure, reading data stored at the known memory locations after completion of the data erasure procedure, comparing the read data and the data of the known data pattern, and determining a verification result based at least in part on the result of the comparison between the read data and the data of the known data pattern.

Abstract: A method for use in repurposing, erasing data from, and/or disposing of an IT asset comprises transmitting a signal, for example an erasure target signal, from the IT asset to a server located remotely from the IT asset, receiving at the server at least part of a profile of the IT asset, and in response to receipt of the signal, for example the erasure target signal, at the server, identifying an action to be performed in relation to the IT asset based at least in part on the profile or part of the profile of the IT asset. The method may comprise transmitting instructions from the server to an erasure client, which instructions at least partially define the action to be performed in relation to the IT asset and in response to receipt of the instructions at the erasure client, performing the action in relation to the IT asset. The action to be performed may comprise an erasure procedure.

Abstract: A method of erasing data using a file-based protocol from a data storage apparatus for repurposing, reallocation to a new user or retirement of the data storage apparatus, the data storage apparatus comprising a memory using a file-based protocol, and the method comprises: receiving one or more signals representative of the available free space of at least one selected region of the memory; iteratively writing files to the at least one selected region of the memory using the file based protocol, wherein: at least one of the files is sized based on at least one of the received signals and the iterative writing of the files comprises writing the files in sequence such that for at least part of the sequence each file is smaller in size than the preceding file of the sequence; and wherein the files are written to collectively occupy all of the at least one selected region of the memory; and the method further comprises receiving an indication that said at least one selected region of memory is full following the
