Formatted by accident · media recovery

Formatted the wrong thing? It’s usually still recoverable.

Although selecting the wrong format does not mean that all of your information is lost for ever; a simple “quick format” will remove an index from the disk and leave the original location of your files on it until overwritten by new data. As soon as you discontinue use of the formatted hard drive, SSD, memory card or USB stick, we can usually recover your data while still located within our facility.

Most jobs — only pay if we recover your data
Any media, any make
!

Stop using the device — no reinstalls, no copying.

Quick format: all files will remain intact until something new is written over them. Therefore, don’t reinstall your operating system; don’t add any new items to the device; take no more pictures on the formatted card; because each of these actions can write data over what remains. The less new data that is written, the more can be recovered from it. Simply place the item off to the side and contact us.

// how formatting happens

The ways media gets formatted.

Virtually every format that we handle is a quick format which leaves the original data unchanged. This means that most of the time, with only a handful of exceptions, the original data is still available for recovery. Below are the cases we see most often:

▤Wrong drive quick-formattedWrong drive, card or stick gets formatted. A quick format writes an entirely new index (a new $MFT on NTFS, or new FAT tables) while leaving the clusters containing your files untouched. As such, most of your files are still located at their original locations.Most commonQuick format◈‘You need to format this disk’A corrupt file system causes Windows or macOS to demand a format, and it goes ahead. However, formatting only rewrites the index, not the data area, so the files beneath are normally unaffected and fully recoverable.PromptCorrupt FS▦Reformatted cardA card has been reformatted in a camera or phone, wiping its FAT or exFAT directory. The photos and clips themselves remain in the flash memory until they are overwritten by new shots, and their signatures let us locate and retrieve them.CardsMedia▣Wiped mid OS-installA drive was repartitioned or wiped during an installation. A new partition table and file system were written to the start of the disk; however, most of your data lies further in than that point and we rebuild the old volume around the new one.OS installDrives◐Overwritten after the formatOnce the damage has occurred, however, the largest risk is that the next time someone uses the device and writes some new information to it, that new information will settle into those now-empty blocks and essentially bury those original files forever. Once a block is reused, there’s no longer any way to recover that file.Time-criticalOverwrite⊘Full format or SSD TRIMModern versions of Windows can use full formatting where they write zeroes to every sector as they go. Additionally, on an SSD, TRIM erases freed blocks in hardware in seconds, both destroying the original data permanently. If you do either, stop immediately.SeverePermanent

// how the recovery runs

How formatted media is recovered.

Our recoveries of formatted media work copy first. Your original device is never actually touched live: first, a forensic image of your original device is made, then the original file system is built upon that image, finally, your files are pulled from that image.

01

Free diagnostic

If you tell us about the device that got formatted along with what happened, and when, we’ll figure out if the lost data can still be recovered. Following that, a written quote will typically be sent within 48 hours.

02

Image it first

Each device is first duplicated to a forensic image; everything we do runs against this duplicate image. Therefore, none of our testing ever affects the original media.

03

Rebuild the old file system

We locate your prior file system (NTFS’s original $MFT and boot sector, FAT and exFAT’s original FAT tables and root directory), often still intact underneath the newly created blank table, and rebuild that file system so your original folder names, file names and date/time stamps will show up again.

04

Deep-scan and carve

Any files we’re unable to link back to the prior file system are carved from the raw sectors based upon their contents: each format type has a unique header and footer (FF D8 / FF D9 for JPEGs, %PDF / %%EOF for PDFs and PK for ZIPs and Office). Therefore files appear even though there aren’t any directory entries associated with those files, and the results of both steps are then combined.

05

Validate the results

All things retrieved will be verified. The signature on all items will be confirmed; documents, images, etc., will be opened and the file’s checksum will be compared to confirm that an item which has been restored, was truly restored. All carved copies of files previously discovered through the metadata will be deleted prior to the data being returned to you.

06

Recover the files

The data will be duplicated into new media in the original order, and you can begin to use it once again.

07

Return your data

The media is posted back to you, or the recovery is made available as a free download for up to 75GB.

A few recent formatted-media jobs on various devices. Identifying details have been removed, and every result was verified.

// CASE 2026-039recovered
SanDisk 256 GBSD card · cameraFormatted

A holiday card formatted inside a camera by accident.

As this was a quick format in a camera, the original data had not been overwritten. We created an image, rebuilt the previous file system and retrieved virtually all of the original photos and clips.

// CASE 2026-033recovered
Kingston 128 GBUSB stickQuick format

The wrong USB stick quick-formatted, key work with it.

The index file simply was re-set while all data remained intact. Upon re-building the file system, every document returned to its prior state.

// CASE 2026-026recovered
WD Elements 2 TBExternal driveReformatted

A drive reformatted during a Windows reinstall.

We restored the original file system after creating an image. Next, we carved out the remainder of the data and were able to recover most of the data before anything else overwrote it.

// getting it to us

Two easy steps.

Simply send your device to us for a free diagnostic and describe briefly what happened. An engineer will review it and confirm your exact quote in writing before any work begins.

// questions

Formatted media — your questions.

The most common questions about recovering formatted drives, cards and sticks.

Usually, if it was a quick format. A quick format writes a new, empty index (a fresh $MFT, or a new allocation table on FAT or exFAT) but leaves the actual file data intact. Where the old file system has survived, we rebuild it to restore file names and folder structures, and anything we cannot rebuild, we carve out by signature. The two exceptions are a full format that writes zeros across the drive and TRIM on an SSD, both of which really do clear the data.

Quick format simply removes the indexes but does not remove the data. Therefore, a new $MFT & boot sector for NTFS, or fresh allocation tables for FAT & exFAT are created, while the clusters themselves remain unchanged. In modern versions of Windows, full format goes further than just removing indexes and clears every sector with zeros thereby destroying the data.

Immediately stop using it. Do not reinstall your operating system. Do not copy anything onto it. And do not save any new files on it because each of these actions overwrite the data that was formatted. Contact us as soon as possible to prevent loss of data. The sooner you stop using this device, the better chance we have to recover your data.

Yes. Formatted memory cards from cameras & smart phones are some of our most common jobs, and since cameras typically use a quick format most photos & videos usually survive. Assuming no new photos/videos were taken on the card after formatting, it is usually possible to rebuild them.

No! Leave it alone. This message usually means that there is damage to either the $MFT, partition table etc. Which makes the volume un-readable. But your data is still there! If you do a format, a new index is written over the old damaged one making recovery much harder. Please send in the device as it is, and we will create a good working version by copying off the damaged one.

Sometimes, though they don’t work as well as a hard drive, memory stick/card and, to put it bluntly, we won’t brag about them. This is because of TRIM. For all internal SSDs that have TRIM enabled when the volume has been formatted, the controller will erase the freed blocks in hardware, within seconds. Often there’s no data left for us to find. If TRIM isn’t enabled on your internal disk, or if your external SSD doesn’t pass the command through, then the possibilities are better and the diagnostic will give you a direct answer.

Laptops, PCs & Macs with their internal disks; standalone hard drives & SSDs; external & portable drives; and also USB sticks, SD cards, microSD cards, CompactFlash cards. As long as it can be formatted, we can normally help.

£250 + VAT for cards and USB sticks and £300 + VAT for hard drives, after a free diagnostic, and in most cases you only pay if we recover your data. As logical recovery, it is one of our lower-cost services, and we confirm the exact price in writing before starting.

Most formatted jobs take anywhere from one to three working days to complete, and many times the job is done faster, and the diagnostic usually comes back within 48 hours. If an urgent job is needed, please let us know and it can go to the front of the queue.

Please bring the media to our Guildford unit (Monday to Friday), 9am to 5:30pm. Or send it to us fully insured. Please seal it up well and include your contact details inside (name, address, phone number, email) so that we can book it in when it arrives. The free diagnostic and written quote will come before any work is done on your media.
