1. A host in communication with at least one Data Storage Device (DSD), the host comprising:

  • an interface for communicating with the at least one DSD; and

    a processor configured to;

    send a request to the at least one DSD via the interface in preparation for sending a write command to the at least one DSD to store data in the at least one DSD, wherein the request is for environmental information indicating an environmental condition of the at least one DSD that is based on a number of times the at least one DSD has exceeded a write unsafe threshold within a predetermined period of time or an amount of time since the at least one DSD has exceeded the write unsafe threshold, and wherein the write unsafe threshold is a predetermined distance from a center of a track on a disk of the at least one DSD;

    receive the environmental information from the at least one DSD via the interface;

    determine whether the environmental information is within a threshold;

    send the write command to the at least one DSD via the interface if the environmental information is within the threshold; and

    perform a precautionary measure if the environmental information is not within the threshold.
