The secret splitting module is configured to recover secret data from at least two pieces of split data using secret splitting and the control module is configured to control reading out or writing each piece of the split data. Secret data is maintained within a virtual drive. The control module is further configured to read out first split meta-data from a first storage device, read out second split meta-data from a second storage device, cause the secret splitting module to recover virtual drive meta-data at least from the first and second split meta-data, and generate the virtual drive based on the recovered virtual drive meta-data.
