Custom Test Procedures for Tape Devices

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.
