Hi everyone, I have a 1TB Seagate external hard drive that suddenly stopped working. When I plug it in, the light blinks, but it makes continous ‘click’ sound (and sometimes a faint beeping noise). My computer isn’t detecting it at all.
I watched a YouTube video that suggested opening the top cover to unstick the heads. Is this safe to try at home? I have very important project files on this drive and I need them back urgently. Please help!

STOP! Do NOT open that drive.
I cannot stress this enough: Opening your hard drive outside of a specialized Clean Room will permanently destroy your data.
The “Click of Death” usually indicates a serious mechanical failure. Here is exactly what is happening inside your drive and why DIY fixes are dangerous.
What causes the “Clicking” or “Beeping” sound?
When you hear that noise, it usually means the Read/Write Heads (the tiny needles that read data) are failing to find the data track. They swing back and forth, hitting the limiter stop—that impact is the “click” you hear.
Here are the 4 most common scenarios we see in our lab:
1. Head Crash (Physical Damage)
-
The Cause: Did the drive fall or get bumped? The heads may have physically touched the spinning platter.
-
The Risk: If you keep plugging it in, the broken heads will scratch the magnetic coating off the platters, turning your data into dust. This is irreversible.
2. Stiction (The “Beeping” Sound)
-
The Cause: The heads are stuck on the platter surface instead of parking in the safe zone (common in Seagate and WD drives). The motor is trying to spin but can’t, creating a “beeping” or “buzzing” noise.
-
The Fix: This requires special tools to lift the heads off safely. Yanking them manually will rip the heads off.
3. Weak Read/Write Heads (Degradation)
-
The Cause: Aging components. The heads are too weak to read the “servo tracks” (the map of the drive), so they keep searching blindly.
4. Insufficient Power (The Only “Safe” Check)
-
The Cause: Sometimes, a loose USB port or a bad cable isn’t sending enough voltage to spin the motor fully.
-
Safe Test: Try a different USB cable and a different USB port (use a rear port on a PC). If it still clicks, stop immediately.
Why you must NEVER open the cover
Hard drives are sealed in a clean environment. The distance between the Read/Write head and the platter is smaller than a fingerprint.
-
Dust is Deadly: A single speck of dust is huge compared to the head gap. If dust gets inside and the drive spins at 5,400 RPM, it acts like a rock, crashing the heads and scratching the data surface.
-
Alignment Issues: The screws on the cover often hold the spindle alignment. Loosening them can misalign the motor, making recovery impossible.
What should you do?
Since the drive is clicking, software cannot help you. Running data recovery software on a clicking drive forces the broken heads to move aggressively, which causes further damage.
Your Action Plan:
-
Unplug the drive immediately. Do not try to “cool it in the freezer” or “hit it” (old myths that ruin modern drives).
-
Bring it to a Professional: This issue requires a Class 100 Clean Room to safely open the drive and replace the donor heads.
At Recovea, we handle clicking drives daily. We have the specialized donor parts and the clean environment required to swap the head assembly safely without exposing your data to dust.
It is better to be safe than sorry. Bring it in for a free evaluation before the damage gets worse.
