The present disclosure generally relates to data storage devices, such as solid state drives (SSDs), specifically utilizing the data storage device memory in the execution of host commands. A controller is configured to receive a command pointer or a data chunk from a host device, mark a destination used for the command pointer or the data chunk, determine whether a last chunk of the command pointer or the data chunk has been received, and determine whether the command pointer or the data chunk uses an illegal combination of locations after determining that the last chunk of the command pointer has been received. The controller is further configured to return an error message to the host device upon determining that the command pointer or the data chunk uses an illegal combination of locations.
