lated power feeds.


SOLUTION (B): Locate an identical logic board (being certain to match make, model, and lot numbers) and replace the problem logic board. If the unit powers up, begin copying data with great haste, you may not have much time remaining before the unit fails again. A hard disk drive that suffers damage from a power fluctuation can also have damage to the actuator (motor) within the unit itself; these malfunctioning components can cause damage to even a new logic board. Contact a data recovery specialist for additional assistance.


SYMPTOM #4: The hard drive unit emits an OCCASIONAL clicking sound.
DESCRIPTION: This is very common and often an overlooked sign of imminent drive failure. One of the locking points for the Cam/Actuator arm has malfunctioned and the arm swings overly wide, causing it to smack against the inner drive unit housing or stop block, which is usually made out of plastic. The drive most likely works and the volume is mounted and functioning perfectly. This condition promotes a false sense of security and will often cause a user to ignore the obvious warning signs. Data should be copied from this drive without delay. The drive will most likely fail soon, although it could function for many months, failing without warning at an unknown time.

SOLUTION (A): Copy data from the drive if the unit still functions and discard the problem drive.

SOLUTION (B): If the drive stops functioning, the cam/actuator arm has likely become locked in position. To temporarily correct this condition, try lightly tapping the side of
