How to Recover Files from a Formatted USB Drive

A USB drive that was formatted, shows as RAW, or asks to be formatted may still contain recoverable data. The key is to avoid writing anything else to it before scanning.

This guide covers both cases: a drive you accidentally formatted and a drive that suddenly asks to be formatted.

Step 1: Cancel the format prompt

If Windows or macOS says the drive needs to be formatted, cancel the prompt. Do not click format just to make the drive usable.

Formatting may create a new file system and make it harder to recover the previous folder structure. If the data matters, recovery comes before repair.

Step 2: Try one safe reconnect

Unplug the USB drive and reconnect it once using a different USB port. If possible, avoid hubs and use a direct port.

If the drive appears normally, copy the important files to another location immediately. If it still asks to be formatted, stop using it and move to recovery.

Step 3: Do not run repair tools yet

Avoid running chkdsk, First Aid, disk repair, or third-party repair tools before recovery. These tools can modify file-system structures. That may make the drive mountable, but it can also make deleted or lost data harder to recover.

Step 4: Install recovery software somewhere else

Install recovery software on your computer’s main drive or another external drive, not on the USB drive you are trying to recover.

For portable tools, run them from another storage device. The goal is to avoid all writes to the affected USB drive.

Step 5: Scan the USB drive

Use a free scan or preview first. If the tool finds files, inspect names, folders, dates, and previews where possible.

If the scan shows multiple partitions or file systems, choose the result that contains files you recognize. For formatted drives, a deeper scan may be needed.

Step 6: Recover to a different drive

Choose a different destination for recovered files. Saving back to the formatted USB drive can overwrite additional data.

After recovery, verify a sample of important files before reformatting or reusing the USB drive.

Tool options to compare

EaseUS is approachable for first-time users and may cover smaller file sets through its current free offer. Stellar is worth checking when preview and file-type support matter. Recoverit may suit users who want broader USB, media, and device checks. Recuva can help only in simpler Windows cases.

For technical users, PhotoRec can search by file signature, but recovered files may need more sorting.

When to stop

Stop if the USB drive disconnects repeatedly, becomes hot, is physically bent, or causes the computer to freeze. Those signs point beyond an ordinary formatting mistake.

Final recommendation

For a formatted USB drive, do not format again, do not run repair first, scan from another drive, preview before paying, and recover to a different destination. Use EaseUS for the simplest guided path and Stellar when file previews and formatted-media handling matter more.
