Abstract
The application relates to utilizing a head assembly, having a default boot-up head and at least one other head, in a depopulated configuration. If, during testing of the head assembly, the default boot-up head is found to be flawed, it designated as faulty in a non-volatile memory in the head assembly. The head assembly with the default boot-up head is used in a data storage device.

An apparatus comprising:
- a head assembly comprising:
- a non-volatile memory configured to store a status of a head in the head assembly,
- wherein the non-volatile memory is inaccessible to the head.
A method of using a head assembly having a default boot-up head that is faulty, the method comprising:
- designating the default boot-up head as faulty in the head assembly,
- wherein the designation of the default boot-up head as faulty is carried out substantially independently of a data storage device in which the head assembly may be used.
