I suspect there may be an issue with the hard drive on my NI PXI(e) Embedded Controller, how can I test it?

You can test the hard drive and memory of your controller with the included BIOS diagnostic utilities on the following NI Embedded Controllers:
  • PXIe-8135
  • PXIe-8820
  • PXIe-8840
Accessing BIOS Diagnostic Utilites
Complete the following steps to start the BIOS Diagnostic Utility.
  1. Power on or reboot your controller.
  2. When the message <F2> to run diagnostics appears, press the F2 key. The first diagnostic utility loads after a short delay.
Hard Drive Diagnostic Utility
The hard drive is tested first upon entry into the BIOS Diagnostic Utilities. A quick test is performed initially, and a more comprehensive test is performed second. You may abort and skip any test by pressing the <Esc> key at any time during that test. After both tests have finished or have been skipped, you will be presented with the testing results. If both tests have succeeded or have been skipped, Press any key to continue is displayed. In order to continue with testing, you will be required to press a key on the keyboard. 

Older controllers may make use of an external Hard Disk Drive Diagnostic utility that is run from a bootable USB drive. 

Note: If either hard drive test fails, the controller is not permitted to boot. You should turn off the controller and replace the hard drive.
