Kevin,
Although NI does not support replacing the hard drive on our PXI controllers, I have a few reccomendations that should help.
Most likely it is problem with the BIOS that you have installed on the hard drive.
Here is the latest NI BIOS revision for the 8175 controller.
If you have further trouble, visit
this website for instructions on how to reformat a hard drive on a PXI controller.
Thanks,
Travis
