1. An apparatus to validate that a correct data segment is read from a storage device, the apparatus comprising:

  • a read request receiver module that receives a read storage request from a requesting device, the storage request to read a data segment of a file or object stored on a data storage device, the storage request comprising one or more source parameters for the data segment, the source parameters comprising one or more virtual addresses that identify the data segment;

    a hash generation module that generates one or more hash values from the one or more virtual addresses;

    a read data module that reads the requested data segment and returns one or more data packets and corresponding stored hash values stored with the data packets, the stored hash values being generated from source parameters of a data segment written to the data storage device and containing data of the data packets; and

    a hash check module that verifies that the one or more hash values generated by the hash generation module match the respective one or more stored hash values returned by the read data module.
