The Custom NTF test lets you select which tests to run: Test
Unit Ready, Inquiry, Rewind, Buffer Test, Filemark Test, Clear All Logs, and
Write/Read/Verify. These tests are similar to the Standard tests, but they implement
the tests more often, and in more locations. These times vary, depending on the
device. By default, all tests are selected.
