Read this before you do anything else
Switch it off now. The beep is a motor being forced.
A beeping drive is usually a spindle motor trying to turn platters that will not move, and the beep is the sound of that repeated attempt. The heads are commonly stuck to the platter surface, and continuing to drive the motor against that can tear the head from its arm or pull material off the surface it is stuck to. Unlike a clicking drive, this one is often failing to spin at all, which means every attempt is force applied to a stationary stack.
Emergency
External hard drive beeping
If your external hard drive is beeping, the most useful thing on this page is above this paragraph, and it is free. What follows is what the fault usually turns out to be, how recoverable this class of failure is, and what it would cost, including the cases we would tell you to take elsewhere.
What this usually turns out to be
The beep is the motor trying to start and not turning, and there are two quite different reasons that happens on a bus-powered external. Either the heads have settled on the platter and stuck there, which physically prevents rotation, or the port is not delivering enough current to spin a drive up from cold. The second is common, benign, and fixable by you in a minute. This is one of the few emergency-sounding symptoms with a genuinely good chance of being nothing.
A portable external is a normal drive inside a plastic shell with a USB bridge board. The bridge fails far more often than the drive does, which is why a dead external is better news than a dead internal.
Stiction: heads stuck to the platter surface
The heads have settled onto the platters and adhered. The motor cannot break them free, and forcing it is what causes the damage.
Seized spindle motor
The bearing has failed and the platter stack will not turn regardless of the heads.
Insufficient powerbetter news
A bus-powered drive on a weak port or a failing adapter can beep simply because it cannot start. Worth ruling out, and better news if so.
What to check first on an external hard drive
- Try a rear USB port on a desktop, or a mains-powered hub. Spin-up draws several times the current of normal running, and a marginal port fails exactly at that moment.
- If the enclosure has a Y-cable with a second USB plug, use it. That plug exists for this reason and is frequently left in the box.
- Give it one attempt on good power. If it spins and mounts, copy your data off immediately and treat the drive as suspect rather than fixed.
What not to do
Do not tap it, drop it, or twist it sharply to break the heads free, which is advice that circulates widely and works occasionally. When it fails it does so by dragging the heads across the surface, and it converts an inexpensive stiction job into a scored platter.
How recoverable this is
Almost always requires the drive to be opened before anything can be read, because the fault is that the platters are not turning. Once the mechanical problem is corrected the data underneath is frequently intact, because the failure is in the moving parts rather than in the recorded surface. That correction is cleanroom work.
What moves it, for your device specifically:
- Whether the platters were damaged during attempts to force them
- How many start attempts the drive has had since the beeping began
- Whether the head stack can be freed without surface contact
- Whether a matching donor drive is available
We will not give you a percentage for your device, and you should be wary of anyone who does. Nobody can know what is recoverable until the media has been imaged and read. What is above describes this class of failure; your drive gets its own answer after an assessment, in writing, at no cost.
What it costs
Assessed free, then referred at no charge
Cleanroom mechanical work
Clicking, seized or head-crashed drives need internal mechanical work in a controlled environment. We don't have one, so we assess it, tell you what we found in writing, and refer it on. That referral costs you nothing here.
Nothing is charged until you have seen a fixed quote for your actual device and agreed to it, and the assessment that produces it is free.
