The fault · a clicking or beeping drive
That clicking is not the sound of your files being wrecked. Not yet. It is a head that cannot work out where it is, giving up, and going round again — and each attempt drags it back across the surface your data is written on. Cut the power and the dragging stops. Cut it soon enough and you keep the good odds.

| On screen | What's behind it | First move |
|---|---|---|
| A regular tick, one to three times a second | Servo marks are what tell a head its position; unable to read them, the arm goes back to the ramp and begins again, without end | Switch it off |
| A thin, high-pitched beep, nearly always a 2.5" portable | Nothing is turning — the bearing has seized, or heads glued down onto the platter are holding the whole thing still | No shaking, no tapping |
| Scraping or grinding sounds | A head is touching the surface: a crash in progress | Data goes with every powered second |
| Chirping noises as it spins up | Failed calibration, frequently following a bump | Off, and left alone |
| Clusters of clicks, then quiet | It resets itself each time a run of retries fails | Break the loop; unplug |
| It only clicks on particular files | One failing head, or damage confined to a single track band | Abandon copying; have it imaged |
Every item gets its own case number on the day it lands here. An engineer traces the fault, gives you a plain assessment of what is realistically recoverable, and puts one fixed price in writing. The diagnosis is free, you are under no obligation, and chargeable work starts only when you say go.
Nothing is plugged in until the mechanics and the platter surfaces have been examined. Should a clicking drive need to spin, it spins to our rules: a few seconds, watched, never left running.
Damaged head stacks are swapped for matched donor parts, seized spindles released, heads stuck to the platter lifted clear without touching it. The drive is then asked for one thing: a single full image.
A hardware imager works the disk gently, stepping over bad regions and leaving the frailest areas until last, so that a sound copy ends up holding the lot. The file system is then rebuilt on that copy, never on the drive.
You get the full list of recovered files first, and nothing is charged until you approve it. Data goes back on fresh media, return postage paid, and the job stays open on our side until you confirm every file opens at your end.
Power off is the entire plan: a head glides a handful of nanometres over the platter, which leaves no room whatsoever when something goes wrong. On the clicking drives that come through here, the thing that best predicts a good result is how fast someone reached the switch after the first click.
It came in ticking roughly once a second, with five years of EPOS records on it. Two donor head assemblies and one long, careful image later, the full ledger reached the accountant and the shop filed its VAT on time.
Usually. Clicking tells you the heads have stopped reading, and nothing at all about what is still on the platters. Fit matched donor heads, image slowly, and most such drives give up most of their data. The harm comes from leaving the drive running, not from the noise.
No. That advice belongs to a far older generation of drives. Put one in the freezer and you introduce condensation and shrinking metal into the mechanism — corrosion and fresh damage piled onto the fault you started with.
The click is the head stack hunting for the factory servo tracks, failing to find them, and returning to the ramp for another go. Broken heads, a dying preamp and scored platters sound identical; only diagnosis separates them.
No. Any software still has to read through the heads, so when the heads are going, each scan drives the very reads that kill the drive.
Switch a failing device on again and you lose a little more. Open a case before you do — the diagnosis is free, whatever it finds.
