Data loss: the first ten minutes

1. Stop writing to the device

Power off, do not restart. Clicking, grinding or beeping: power off and leave it off.
Take the card or USB stick out of the camera, phone or computer.
Do not format, initialize, repair, or run first-aid and check-disk tools.
Do not save recovered files onto the same drive: they can overwrite the files still to be recovered.

2. Check the boring answer first: backups

Cloud sync and photo libraries often still have the files. Check from another device before touching anything.
Time Machine (Mac) and File History (Windows) keep previous versions. So do email attachments and messaging apps.
Restoring a backup onto the failing drive can overwrite what is recoverable. Restore to a different disk.

3. Match the response to the situation

Deleted by mistake, drive healthy: recovery software in read-only mode is a reasonable next step.
Drive not detected at all: stop. Software cannot see it either. Check power and cables once, then stop.
Any physical event (drop, water, heat, smoke, power surge): no software route. Stop and ask a professional.
Phone or console storage: expect encryption. Replacement parts and restores are different from recovery; check what each can actually give you.
RAID or NAS: do not rebuild to rescue data. A rebuild reads every surviving drive and writes reconstructed data onto the array; one wrong assumption can finish the job.

4. When to stop and ask a professional

The data is irreplaceable and not backed up. Every attempt is a risk; spend them wisely.
Strange noises, repeated disconnections, or a drive that will not power up.
A first careful software attempt found nothing. A second, harder attempt usually makes it worse.

Never, on this device

Format or reformat “to fix it”.
Freeze, open, or shake a hard drive.
Install anything onto the drive with the problem.
Trust a tool that promises a guaranteed 100% recovery.

Infographic: Data loss, the first ten minutes. Pause first: clicking, grinding or beeping means power off and leave it off. One, stop using the device: power off, remove the card or USB stick, do not format or run repair tools, never save recovered files onto the affected drive. Two, check backups elsewhere: cloud storage and photo libraries from another device, Time Machine and File History, restore to a different disk. Three, choose the right route: deleted files on a healthy drive, cautious read-only software installed elsewhere; not detected or damaged, stop and seek advice; phone, console, RAID or NAS, specialist advice, never rebuild to rescue files. Four, know when to stop. Never: format to fix it, freeze, open or shake a hard drive, install onto the affected drive, trust 100% recovery promises.

How to use this card

The card is a starting point, not a diagnosis. It gives the steps that keep a bad situation from getting worse, and the boundaries where do-it-yourself ends.

Not sure which situation you are in? The guided help tool asks a few short questions and points at a route. Your answers stay on your device: the site does not collect them.
