Devices · internal hard drives
Desktop and laptop hard drives fail the same few ways: heads, motor, electronics or firmware. What decides the outcome isn't the fault — it's what happens next. Power it down, and let the lab take it from there.
Talk it through with an engineer
01273 964902
| The message | What it means | First move |
|---|---|---|
| You need to format the disk in drive X: before you can use it | The file system reads as RAW — the index is damaged, the data usually isn't | Don't format — power down |
| Data error (cyclic redundancy check) | Read verification failing, almost always bad sectors on the platters | Stop copying, image it |
| The request could not be performed because of an I/O device error | Windows can no longer talk to the drive reliably | Power down, note the model |
| Windows detected a hard disk problem | SMART self-monitoring is predicting failure | Back up now or image |
| Error 0x800701E3 — fatal device hardware error | The drive is failing at hardware level mid-transfer | No more retries — lab job |
| S.M.A.R.T. Status BAD at power-on | The drive's own health check has tripped at boot | Don't keep booting from it |
| BIOS shows 0GB or the wrong model name | Firmware / translator corruption — the drive has forgotten itself | Firmware-level lab work |
Your device is logged with its own case reference the moment it arrives. An engineer assesses the fault, confirms what's actually recoverable, and you get a fixed price in writing — no diagnosis fee, no obligation, and no paid work until you say go.
The drive goes onto a hardware imager that reads around bad areas gently instead of hammering them — your data is secured to a healthy copy before anything else.
Failed heads are replaced with matched donor parts; seized motors are released; damaged boards are repaired with the original ROM carried across.
The file system is reconstructed from the image, and you see a full file listing before you pay a penny of the recovery fee.
Before you pay the recovery fee you approve a full listing of what came back. Your data returns on new media with free return postage, and the case only closes once you've confirmed everything opens on your side.
How often do drives actually fail? Backblaze's public Drive Stats — the industry's only large open dataset — recorded a fleet-wide annualised failure rate of 1.36% for 2025 across 344,000+ datacentre drives, down from 1.57% in 2024. That's constant-workload server duty; consumer drives fail less often but far less predictably.
Two failed heads and a drive that hadn't spun in weeks. Donor heads went in, the drive imaged at 96% on the first pass, and the accounts, invoices and photos all left the lab verified.
Usually not. Clicking means the heads can't read, not that the platters are blank. With matched donor heads and careful imaging, most clicking drives give most of their data back. The killer is continued use, not the click itself.
Often yes, but be straight with us about it. A drive opened outside the lab is quoted individually after we've seen the platters, and no-fix-no-fee terms may not apply to prior-damage cases.
Diagnosis is free and the price is fixed in writing before any paid work starts. Logical faults sit at the lower end; mechanical work with donor parts costs more. You'll always know the number first.
Yes — IDE, early SATA and SAS server drives are all routine here. Age changes the tooling, not the outcome.
Every restart of a damaged device costs data. Open a case first — the diagnosis is free either way.
