The external drive is Scotland’s favourite backup and its most-dropped device — a hard drive in a plastic shell, living on desk edges and in laptop bags. When yours stops mounting, gets knocked off the sofa or clicks in its case, the bench sees three distinct patients. The look, as always, is free.

An external is two things: the drive inside, and the bridge board that turns it into USB. Bridge failures — dead ports, snapped connectors, fried power circuits — are common and the better diagnosis, because the drive within is often untouched. But here’s the trap DIYers hit: many externals encrypt on the bridge itself. WD My Passports and several Seagate ranges pass data through hardware encryption on that little board — shuck the drive, connect it directly, and you get gibberish, not files. The bench decrypts through the proper channel; if you’ve already separated drive from enclosure, send both, including the board.
Externals fail mechanically more than internals for one unfair reason: they fall. A powered, spinning drive that hits the floor tends to damage heads or platters at the worst moment — mid-operation — and the post-drop click is exactly the head damage it sounds like. The garden-variety story from our own postbag: an external dropped onto concrete while working in the garden. If that’s today’s story, the rules are the mechanical rules: no retries, no software, padded box, Princes Street. Desktop externals and multi-bay units (LaCie Big, WD Duo) add a wrinkle — some stripe data across two disks as RAID 0 — so send every disk from the enclosure, labelled.
Decent odds it's the enclosure: bridge boards and their connectors fail far more gracefully than drives do. That's a favourable diagnosis, sometimes a same-week turnaround — but resist confirming it yourself by shucking the case, because hardware-encrypted models turn to gibberish outside their own bridge.
It's the classic drop injury: head damage, mechanical, recoverable in most cases via donor parts and careful imaging — provided it isn't powered repeatedly 'to check'. Every retry is the damaged heads over your platters again. Off, boxed, sent.
Yes — routinely. Their hardware encryption lives on the bridge board, so recovery works through or around that layer properly. If the enclosure or its board has been separated or replaced, include the originals in the box; they can carry the keys to your data.
A free diagnostic first, always — then a fixed written quote before any work begins. No surprises on the invoice, because there's no invoice until you've approved the number.

Getting a device onto this bench only takes two moves, and the clock on your free look starts the moment it lands.
Strip out cables, caddies and power bricks — none of it helps — wrap the device so it can't shift in transit, and either post it insured to 83 Princes Street, Edinburgh EH2 2ER or bring it in yourself. Tuck a note of what happened in with it, and enclose the shipping form if you've printed one.
Arrival gets confirmed, the diagnostic runs at no cost to you, and the call that follows names the fault and states a fixed price. The bench stays idle on your device until you say go.
£300 + VAT fixed, free diagnostic first. If it’s an encrypting enclosure, keep the board with the drive — the bridge may be the only key.
