FAIL Servo Op=0100 Resp=0003 Doesn’t Always Mean Head Failure

,

FAIL Servo Op=0100 Resp=0003 is one common error message in Seagate patient hard drives with head or platter surface damage. But sometimes, this error outputs in the COM terminal and the drive is normally accessed for data recovery and sometimes it is caused by firmware corruption.

When this error keeps coming and cannot enter F3 T>, it is usually head failure. When this error comes with other error messages, users need to diagnose the patient HDD further to find out the failure reason. The following is one working hdd with both firmware area and data area normally accessed.
