Fix: Deep Scan Not Working or Getting Stuck

Deep scan reads a drive's raw sectors rather than relying on the operating system's shortcuts, which means it's more sensitive to permission restrictions and drive health than a quick scan is. Most reports of it "not working" trace back to one of a few specific causes.

Q

Run the app as administrator first — that alone resolves most stalls. If it still stalls at the same percentage every time, that can point to a failing sector on the drive itself.

Run as administrator

Deep scan needs raw disk access, which a standard Windows user account can silently restrict. Right-click the application and choose "Run as administrator" before starting the scan — this resolves the majority of scans that appear to hang at 0%.

Scan stalls at the same percentage every time

If the scan consistently freezes at one point, that section of the drive may contain a failing or unreadable sector. Try scanning a different partition or a smaller folder to confirm — if only one area causes the stall, the drive itself, not the software, is the likely cause.

Use the Windows or macOS button on this page. For the installer, run it with administrator rights; for the portable ZIP, extract it to a drive you're not scanning.

2. Scan, preview, restore

Pick the drive or device, run quick scan first, switch to deep scan if needed, then restore selected files to a different drive than the one you scanned.

FAQs

It depends heavily on drive size and speed — anywhere from 20 minutes for a small USB stick to several hours for a large, slow hard drive.

Yes — canceling doesn't affect the drive itself, though you'll only see results found up to that point.
