An implementation of such a method includes generating a device configuration ledger block based on initial assembly of components of a storage device, storing the device configuration ledger block on a node of a distributed ledger, detecting an activation of the device; in response to detecting the activation of the device, generating a current distributed ledger block based on current assembly of components of the storage device, comparing the current distributed ledger block with the device configuration ledger block, and in response to determining that the current distributed ledger block does not match with the device configuration ledger block disabling the operation of the device. ## Claims ### Claim 1 A method comprising: generating a device configuration distributed ledger block based on a hash of initial assembly of components of a storage device;
