I've tried several different drivers and this is the only one that would work. I know it's not a large file. There's a read me file in side, follow it to a "t"! You will also need a direct tape access software program for the windows back-up program to recognize it. You also can't assignthe tape drive a drive letter with out the DTA software. It's not that difficult to do, just tedious. I'm not a guru, just followed the directions.
