Through our code we are able to perform write on disk on X-Serve machine but our problem is that if we try to perform write using the same code on G5 (desktop machine) then it does not write on the disk. Please see the configurations of our machine and please let us know if this is due to difference in system configuration or firmware. We guess both this machine should be same for writing the driver code form developers point of view please correct me if I am wrong.
