<p>An external device 20 comprises a boot loader 24 for an external operating system (OS) and partitioning information 22 of an expected location of a partition in data storage 11 of a computer 10 to which it can be connected. Preferably the external device also includes second encrypted data units of reference partition table data 220 for the data storage. The data storage 11 comprises a partition 122 and first encrypted data units of partition table data 120. Allowing the external OS to access the encrypted data, upon connection of the external device to the computer, by instructing to boot the computer from the boot loader; and during or after booting of the computer: comparing the partition information of the first and second encrypted data units; and if they match, allowing the external OS (112) to access, based on the partitioning information, the data storage. The comparison may be of hashes of the partition table data and the method allows users to bring your own device (BYOD).</p> |
