It happens in one distracted second — the format dialog, the wrong drive letter, and a sick feeling as the progress bar runs. What separates people who get their data back from people who do not is rarely the software. It is whether the next ten minutes were calm or panicked.
Maybe you meant to format a pen drive and chose the external hard disk. Maybe Windows Setup formatted the data partition. The mistake is made; it cannot be un-clicked. But understand this clearly: a format is the beginning of a recovery case, not the end of one. On a hard disk, a completed quick format usually leaves the data area almost untouched. The losses happen afterwards — in the rush to fix it. This is the calm order.

The urge to act fast is the danger. Do not close and reopen things randomly, do not start copying files to test the drive, and above all do not reinstall Windows or restore anything onto that drive. Installations write gigabytes across exactly the space your data is waiting in. If the wrong drive is external, unplug it now. If it is the PC's internal drive, shut the PC down completely. A powered-off drive loses nothing further; every debate can happen while it sleeps.
While it is fresh, note the facts that will guide the recovery: which drive it was, roughly how full it was, what mattered most on it (photos, office documents, one project folder), whether it is a hard disk or SSD, and whether the format was quick — seconds to finish — or the long kind. If the PC was mid–Windows-installation when it happened, note how far the setup got, because setup writes data progressively. This small list prevents the classic tragedy of recovering terabytes of junk before the one folder that mattered.
Attach the drive to a healthy computer as a secondary drive. Run the deep scan and let it complete without interruption. Recover in priority order — the irreplaceable first — always to a different drive, and verify each important file opens before moving on. Expect the honest mix: much of a hard disk's content typically returns after a quick format, some files will be damaged, and raw-scan results arrive with generic names that need sorting. Boring is good. Boring is what success looks like in this job.
If the drive is an SSD, the calm order still applies but the clock is brutal — TRIM may already have erased the freed blocks, so scan as soon as the setup is ready and expect less. If the drive is making clicking or grinding sounds, skip the home recovery entirely: power it off and read the lab guide in this set. And if the format was a completed full format, be honest with yourself early — the data area was zeroed, and the calmest correct action is to accept it and rebuild from whatever copies exist elsewhere.

Yes — shut the machine down. Setup continues writing Windows files onto the drive the longer it runs, and it does not need to finish for the PC to be safe. You can redo the installation later, after recovery, onto the correct drive.
For recovery, identical — the physics is the same. The real question is whether the primary copies of those files still exist. If yes, the calm move is simply to re-copy them and rebuild the backup, no scanning needed at all.
