Compared with disk failure,head related failure occur in particular HD(head) from the first

cylinder and this is occurred continuously.(it is occurred in two more heads)

If failure is continuous, we are confused if it is head failure or disk failure. At this time

read the edge of cylinder again then it is head failure if error still be continuous at the

particular head and disk failure in sporadic case. And failure occurred with changing cylinder

and head continuously, it is called assembly failure in inner HDA or caused from other problem.

(HDA related failure )
