1. A method for implementing an error detection scheme to read/write requests generated by an application program in a host system to a storage device, comprising:

  • receiving with a driver program in the host system a write request from the application program to write data blocks at a first size to target data blocks in the storage device, wherein the target data blocks in the storage device have a second size, wherein the second size is larger than the first size;

    generating with the driver program a checksum for each data block in the write request;

    transmitting with the driver program the data block with the checksum to the storage device, wherein the storage device stores the data blocks and checksums in the target data blocks.
