An example system may include a processor and a non-transitory machine-readable storage medium storing instructions executable by the processer to record, responsive to a first boot of a computing device, storage device identification data and storage device communication path data for a storage device of the computing device, generate a storage device hash value, characterizing a storage configuration of the computing device, from the recorded storage device identification data and the recorded storage device communication path data, and store the storage device hash value to be compared to a subsequently generated storage device hash value characterizing an updated storage configuration of the computing device at a second boot of the computing device.
