Seagate External Hard Drive Clicking After Power Surge - Can Data be recovered?
Quick Answer
Yes. Power surges often damage the drive’s electronics or firmware, not the actual data stored on the platters.
Common Symptoms
Clicking sounds immediately after a power surge
Drive no longer mounts or is not detected
Burning smell or a completely dead circuit board
What NOT to Do
Do not replace the PCB yourself
Do not keep testing the drive with different power sources
Seagate drives store adaptive data in ROM — improper handling can permanently prevent recovery.
Professional Fix
PCB repair or donor board matching
ROM chip transfer (when required)
Firmware stabilization before imaging
Typical Success Rate
75–90%, depending on the extent of electronic and firmware damage.
When DIY Makes It Worse
Each power-on attempt after a surge can further damage electronic components or corrupt firmware, reducing the chance of successful recovery.
Next Step
Power the drive off immediately and request a free professional evaluation.
