Cause of loss · a drive formatted

Birmingham formatted drive recovery. It comes down to one word — quick format, or full?

Nearly every accidental format is the quick kind. It drops a clean, empty index on top of files that have not shifted a single sector, and as ways of losing data go, there are far worse. A full format that is left to run its course is a different case, and you should hear that from us before you pack a parcel, not after.

What each kind of format does.

A quick formatOnly the index is swapped out; the data itself does not move. The drive looks empty, and yet whole folder trees usually come back.
The full format, post-VistaMicrosoft changed this with Vista: as a full format works across the disk, it lays a zero into every data sector. Once one has reached the end of a hard disk there is nothing to retrieve, whatever a firm with an invoice to raise may claim.
clean, and clean allOne takes out the partition table and leaves everything below it untouched; the other writes zeros across the whole disk. A single word separates an afternoon's work from a total loss.
Where SSDs differTRIM usually fires the instant an SSD is quick-formatted — a Seagate or WD unit will start emptying its own cells with nobody having asked. More often than not the race is lost before the mistake even registers, but cut the power and phone us anyway.

Case opened, and the diagnosis costs nothing Free

Every item gets a case number of its own the day it lands. An engineer then works out what has actually failed and tells you plainly which files have a real chance of coming back and which do not. Only then does a price follow: one figure, fixed, in writing, and it costs you nothing to see it. Nothing is charged until you say yes.

Work out which one ran

Quick or full, clean or clean all, finished or stopped part-way — those answers shape everything that follows, so an engineer pins them down before anyone is promised a thing.

Lift the old index back

Working on the image, whatever is left of the earlier file system is pulled out from under the new one and put back together. Where enough records survive, filenames, dates and the folder tree come back along with the data.

Carving takes the remainder

Where nothing of the structure remains, each file type is spotted by its own byte signature and taken off the image intact, with names put back wherever a surviving clue allows.

Approved by you, then posted back

No invoice is raised until the full list of recovered files has sat in front of you and you have said go ahead. Your data comes back on media we buy new, posted at our expense, and the job is not closed here until every file has opened on your own machine.

What the first look turns up

  • Vista is the dividing line — plenty of advice online still says a full format 'leaves your files where they are'. That held for XP and has been wrong ever since.
  • A cancelled full format is not the end — the zero pass runs from the front of the disk forward, so what sat early is gone while the far end can still be intact.
  • One word, two very different outcomes — in diskpart, clean removes the partition table; clean all zeroes the lot. Few typing errors are as expensive.
  • A reinstall on the wrong disk hits twice — the format first, then gigabytes of new Windows laid down on top of it. Every minute it runs costs you more.

Here is the position, plainly put: if all that happened was a quick format, you are in good shape. Let a full format finish, or type clean all into diskpart, and nothing remains to search for, because a zero has been written deliberately into each sector — the behaviour of every Windows release since Vista. If a company tells you it can undo a completed full format, ask it to explain how.

The fitter formatted the family archive, not the spare

A quick format rewrites the index and leaves the data where it lies, which is the whole reason this one came back. Two matching 2TB disks sat in the same tower, and the fitter wiped the family archive rather than the spare. Nothing was written afterwards, so the archive listed out exactly as before.

Before the parcel goes.

Do this first

  • Stop the moment you realise
  • Record the exact command: quick, full, clean, or clean all
  • Shut it down; mark which disk it is
  • List anything written to it since

What not to do

  • Putting Windows back on that very disk
  • A second format 'to put it right'
  • Downloading recovery software to the volume you formatted
  • Hoping a finished full format can be reversed — on a hard disk it cannot

The questions that come up every week.

Is anything left after a quick format?

Nearly all of it. A quick format on a hard disk swaps the index for an empty one and touches nothing else, so every file is still lying in the same sectors. As long as nothing has been saved over the top, whole folder trees normally come back with their names.

Does formatting wipe it for good?

A full format that reaches the end does: since Vista, Windows writes a zero into every sector as it passes. A quick format does not, and that distinction settles most cases.

I formatted the wrong disk. Now what?

Put it down, switch the machine off, and let it be imaged. Every byte written after the error goes on top of files that were still coming back.

Does any of this apply to an SSD?

It is the exception. A quick format on an SSD normally fires TRIM, and the controller starts wiping cells of its own accord seconds later. Cut the power and ring us straight away: of all the format jobs, this is the one measured in minutes.
