Devices · portable and external disks
A drive you carry gets bashed about in ways a desktop disk never is — and it carries an extra component that goes wrong all by itself: the USB bridge. Both faults can be undone. Trial and error cannot.

| The wording | What that tells you | First step |
|---|---|---|
| You need to format the disk in drive X: before you can use it | The file system has gone RAW, often after a yanked cable; your files remain | Don't hit Format |
| USB device not recognized — the last USB device you connected malfunctioned | Nothing is enumerating — bridge or disk | Swap the lead once, then leave it |
| Unknown USB Device (Device Descriptor Request Failed) — Code 43 | The device never reports its identity to Windows | A fault in the bridge — bench work |
| The drive is not accessible. Data error (cyclic redundancy check) | The disk inside has bad sectors | Leave it unplugged |
| Not Initialized or RAW in Disk Management | Unable to read it, Windows suggests erasing | Refuse; initialising wrecks the data |
| One of the USB devices attached to this computer has malfunctioned | The caddy has lost power or its bridge | Usually the board rather than the disk |
As soon as it lands with us, your device gets its own case number. An engineer works out the fault, says what can genuinely be pulled off, then puts one fixed price in writing — no charge for diagnosis, no obligation, and no chargeable work until you approve it.
Caddy faults and disk faults get told apart first — plenty of 'dead externals', old Iomega and LaCie ones included, are sound drives behind a failed bridge.
On WD units and plenty of others, the encryption sits in the bridge chip itself. We lift the keys off that original board so your files decrypt properly, instead of coming back as scrambled sectors.
Hardware imagers take a sector copy, the directory structure is rebuilt from that clone, and everything comes back to you on fresh media with the postage covered.
You sign off a complete list of the recovered files first; only then does the recovery fee fall due. Everything returns on fresh media, postage paid, and the job stays open until you confirm the files open at your end.
Worth knowing: those 2023 SanDisk Extreme portable SSD faults ended in a class action against Western Digital, with 2TB and 4TB models shedding files out of the blue — and the firmware patch that followed never fixed the root cause. If yours is playing up, get an image taken now.
A clicking drive, and nine days until a dissertation was due. Donor heads went on, a patient image followed, and the bridge's encryption keys moved across — every chapter and reference came back with days in hand.
Post the lot, damaged enclosure included. Plenty of models keep the encryption keys on the USB bridge board, so without it even a perfectly good drive reads as noise.
No. It tells you the file system is unreadable, not that the drive is blank. A format overwrites the very structures we rely on to rebuild your files.
Travel treats drives badly — vibration, bumps and swings in temperature. A drive that was already borderline will often die the first time it is powered up on arrival. We hear that story on the bench all the time.
Nearly always. Treat the caddy as expendable; what counts is the condition of the drive and its PCB within — and whether the bridge chip is alive enough to hand over its keys.
Powering a damaged device up again costs you data. Start a case first; diagnosis is free whatever you decide.
