The symptom · a drive nothing will show
Three questions in order will name the broken component. Does the BIOS list the drive? Does Disk Management? Does Explorer open it? Wherever it drops out of that sequence is your answer — electronics, firmware, or the volume — and your documents live in none of the three. Drives reach this bench from Nottingham and the rest of Nottinghamshire with the same sentence attached: the computer cannot see it. A circuit is what that sentence describes. One drive is £300 + VAT, the assessment ahead of it is free, the figure goes to you in writing before any chargeable work begins, and no fee is charged on most jobs unless your files come back.

| What it looks like | What usually causes it | What that means for you |
|---|---|---|
| Windows says Unknown, Not Initialized | The drive replies; missing are a valid signature and a usable partition table | Refuse that prompt |
| Windows wording: “…before Logical Disk Manager can access it” | Say yes and an empty partition map replaces the whole thing | Turn it down, then unplug it |
| Disk Management says No Media | Only the controller is answering. Nothing behind it can be reached, so this is hardware rather than a logical fault. | Leave it unplugged from now on |
| The BIOS shows no drive at all | Electronics or firmware: a dead board, a shorted protection diode, or service-area code that refuses to load | Repair down at component level |
| The BIOS lists a 1TB disk as 0MB | Damaged firmware, or a damaged translator, which is why the capacity reported is nonsense | Firmware tools, not recovery software |
| It takes power and does nothing | The board's supply side has failed, taking the TVS diode short with it | Recoverable, as a rule |
Your device picks up a case number the day it arrives, and an engineer then establishes what has genuinely gone wrong — at no cost, and ahead of everything else. Two things come back to you together: a plain account of what can be lifted and what cannot, and one fixed figure in writing. Agree to that figure, or turn it down and pay nothing.
Nothing is taken apart here, and nothing runs unattended. A moment in the BIOS. Disk Management next. Then a look in Explorer. From there the whole job narrows to one of three: mending electronics, rebuilding a service area, or repairing a file system against the copy.
Off comes the shorted TVS diode and on goes a fresh one. Where a board is past saving, a donor deputises for it — carrying your own ROM chip, since the adaptive values on it were taken from your own platters and suit nothing else.
The sector-by-sector copy is taken the moment the drive answers. Everything afterwards happens against that copy, with your own drive on a shelf, untouched.
The file list reaches you before any invoice does. Say yes and it is billed; say no and it is not — and on most jobs, if nothing comes back there is nothing to pay. Whatever comes off goes home on media bought in for your case, carriage at our end. Nothing here is closed until you have opened those files on your own machine.
Worth holding on to: an electronic or a firmware fault accounts for almost every drive that arrives invisible to its computer. Both exist to handle the introductions between a disk and a machine, and neither is where documents are kept. So an absent drive is reporting a hardware problem of its own, nothing more, and that is why this fault ends well more often than most. Finding out which of the two it is costs you nothing.
Mains power failed overnight at a Newark farm office, and by morning the desktop showed one disk where there had been two. Silent WD, no entry in the BIOS, and the TVS diode on its board was the fault. Its own ROM went across to a donor PCB, and the full image was off within two days of the parcel arriving.
Usually, yes. A dead board gets repaired or exchanged, and whatever killed it seldom pushes past the electronics into the platters, or into the NAND behind them. As jobs go, a drive with no sign of life in it is among the more predictable ones.
Never. A blank partition map is what that box writes, laid straight across the one that records where everything is. Say no, take the drive out, and get an engineer onto it before anything else has a turn.
No. What a drive like that has mislaid is its way of introducing itself, not anything written onto it. The fault sits in the electronics, or in firmware kept in the service area. Neither of those places holds a single one of your files.
Very probably. A spike gets absorbed by a protection diode, which is fitted so that it shorts and dies before anything further back does. The electronics went; what you saved is still where you saved it.
The look costs nothing. What comes back to you is a file list — what opened, what did not — plus one figure to finish the job, in writing, before anything chargeable begins. Most jobs carry no fee at all unless the data comes back. Leave the drive switched off until you have that list.
