External hard drive recovery, UK-wide.

A corrupt hard drive — one that’s suddenly unreadable, asking to be formatted, or showing as RAW — usually still holds all your data, sitting intact behind a damaged file system. The data isn’t gone; the map to it is. And if you’re asking how to recover a crashed hard drive, the single most useful step is to stop using it: a crashed hard drive that’s clicking or grinding is failing mechanically, and every extra minute powered on risks the platters.

Whether it’s a logical fault (corruption, a bad partition, a format prompt) or a physical one (a crash, failed heads, a dead bridge board), the fix is the same idea: image the drive first, then rebuild your files from the copy. That applies to every make we see — including a LaCie hard drive that needs repair or recovery, since LaCie enclosures are usually just a Seagate or Toshiba disk in a metal shell and are recovered the same way.

This is the question that decides everything, and it’s the reason not to panic the moment an external stops mounting. Inside almost every portable and desktop external is an ordinary 2.5" or 3.5" hard drive — or, in slimmer models, a soldered SSD — connected to the outside world through a small USB-to-SATA bridge board in the enclosure. That bridge, the cable, the socket, or the enclosure’s power circuitry can each fail on their own, leaving a completely healthy disk that simply can’t be reached. When that’s what has happened, recovery is often quick and inexpensive: we take the drive out of its casing, read it on dedicated equipment, and the files come straight off.

There is one important exception, and it catches people out. Many Western Digital externals — most My Passport models and some My Book units — encrypt their contents in hardware, at the bridge, and they do it by default whether or not you ever set a password. On those drives you can’t simply pull the disk out and read it: the raw sectors are scrambled with a key that lives inside the enclosure you’re trying to bypass. Recovering an encrypted WD with a dead bridge means repairing or matching the original board, or using your password to derive the key — a very different job from a plain enclosure swap. Knowing the difference is exactly why guessing at home — swapping cases, forcing the drive on and off, running Windows’ ‘repair’ — so often turns a straightforward recovery into a difficult one. We test which fault you actually have before touching anything else.

Externals lead hard lives — carried in bags, knocked off desks, unplugged mid-write — so they tend to fail in a familiar handful of ways, each needing a completely different response:

Enclosure, bridge, cable or port failure. The drive is fine; the path to it isn’t. Symptoms are a drive that’s dead on one cable or port but the light still flickers, or that spins up but never appears. Often the cheapest, fastest kind of recovery — once we’ve confirmed that’s the fault and ruled out encryption.

Dropped or knocked. Portable drives are at their most fragile while spinning, and a fall can drive the read/write heads onto the platters. If yours was dropped and now clicks, buzzes or isn’t recognised, switch it off and leave it — this is a clean-bench job (see clicking and grinding drives), and every extra power-on risks turning recoverable data into scratched, unrecoverable platters.

‘You need to format this disk’ or a drive showing as RAW. The file system is corrupt, not the data. Your files are almost always still there, and formatting is the single action most likely to bury them for good. Leave it exactly as it is and let us image it and rebuild the file system from the copy.

Clicking, beeping or grinding. Mechanical failure — a failing head stack or a seized motor. No software can fix this and running scans only makes it worse; it needs the clean bench, matched donor parts and careful imaging.

Won’t spin or isn’t detected at all. Could be the bridge, a burnt PCB after a power surge, or corrupt drive firmware. The data is usually intact — it’s the electronics that have failed — and the fix is board-level rather than software.

Slowing down, freezing or throwing read errors. A drive developing bad sectors is a drive on its way out, but usually still readable. Don’t keep working it — get it imaged now, while the sectors that still read can still be copied.

Accidental deletion, format or a lost partition. Purely logical, and very recoverable — provided you stop writing to the drive immediately, because new data overwrites the old.

More external drives are lost to well-meaning first aid than to the original fault. A few things to avoid while you decide what to do:

Don’t keep plugging it in and out. If a drive is clicking or struggling, every power cycle is another chance for the heads to damage the platters. One or two attempts to rule out a bad cable or port is sensible; repeatedly forcing a sick drive is not.

Don’t format it when Windows asks, and don’t run CHKDSK, Disk Utility’s ‘First Aid’ or similar repair tools on a drive that matters. Those tools write to the disk to ‘fix’ the file system, and on a failing or already-corrupt drive they routinely make data harder or impossible to recover.

Don’t run recovery software on a drive that’s clicking, slow or throwing errors. A deep scan hammers the disk with reads for hours — exactly what a dying drive can’t take. Software recovery has its place, but only on a mechanically healthy drive with a purely logical fault.

Don’t put it in the freezer. It’s an old myth; the condensation it creates does more harm than the cold ever solved. And don’t open the enclosure and reseal a bare drive if the fault is mechanical — platters exposed to ordinary room air pick up dust that a clean bench exists to keep out.

What does help: keep the drive dry and still, note anything you remember about it (for an encrypted WD, your password is the key), and get it looked at before the fault gets worse.

Once a drive is out of its case, the recovery happens at the disk level, so the badge on the front matters less than what’s inside — and we see them all. Western Digital (My Passport, Elements, My Book), bearing in mind the hardware encryption above. Seagate (Expansion, Backup Plus, One Touch, the older GoFlex range). LaCie rugged, Porsche Design and d2 drives — usually a Seagate or Toshiba disk in a metal shell. Toshiba Canvio, Iomega, Buffalo, Adata, Verbatim, Transcend and the rest.

Portable SSDs are their own discipline. Samsung T5, T7 and T9, SanDisk Extreme, Crucial X-series and similar often solder the memory straight to the board, so when a controller dies there’s no drive to ‘remove’ — we read the NAND flash directly using chip-off and monolithic techniques, then rebuild the data from the raw chips. And if your external happened to hold a cryptocurrency wallet file that’s now stranded on a dead drive, that sits right in our wheelhouse — recover the file first, then, if it’s password-protected, see crypto wallet recovery.

Every external starts with a free diagnostic, and the first test is the simplest: is it the box or the disk? We check the enclosure, bridge and power, and confirm whether hardware encryption is in play. If the enclosure is the fault and the drive is unencrypted, we lift it out and read it directly — often that’s the whole job. Where encryption is involved, we work through the original board or your key rather than around it.

If the disk itself is the problem, it goes to the right bench for the fault. A corrupt file system is imaged first and rebuilt from the copy, so your original is never altered. A mechanically failed drive is opened in clean-air conditions, given matched donor heads or parts where needed, and imaged sector by sector — slowly and repeatedly on the weak areas — onto a healthy target. Everything downstream then happens on that forensic image, which means the recovery process itself can never make your situation worse.

When it’s done you get a full list of the recoverable files to check, and a fixed written quote, before you decide whether to go ahead. On most jobs it’s no fix, no fee. And because the whole thing runs by insured, tracked post or by drop-off at our Belfast lab, you don’t need to be anywhere near us — we recover external drives for people right across the UK and Ireland every week.

External-drive recovery is priced per case, because a healthy disk behind a dead enclosure and a dropped drive that needs a clean-bench head transplant are worlds apart in effort. What stays the same is the honesty: the diagnostic is free, you get a fixed written quote up front, and on the majority of jobs it’s no fix, no fee — if we can’t recover your files, you don’t pay the recovery fee. No surprise charges appear once work is under way, and nothing chargeable happens without your say-so.
