What Do High, Low, and Unknown Recovery Chances Mean?

High, low, and unknown recovery chances are scan-status estimates used to help judge whether found files may be recoverable. A high status usually means file records or structure look more intact. A low status often points to corruption, partial overwrite, missing fragments, or damaged metadata. Unknown status means the scan cannot confirm file integrity yet, so preview and post-recovery testing are still needed.

Step 1
Review the recovery status shown after scanning. Look for labels such as high, low, or unknown beside each file or result group.
Step 2
Preview files when preview is available. A working preview often suggests better integrity, especially for photos, videos, documents, and audio files.
Step 3
Prioritize files marked with higher recovery status first. Save recovered files to a different drive to avoid overwriting remaining lost data.
Step 4
Test a small group of low or unknown-status files before recovering a large batch. Open recovered copies and verify file size, format, and content.
Step 5
Stop using the source device if results are poor or scan quality drops. Continued use can overwrite deleted data, and unstable hardware can worsen during repeated scans.

Common Issues and Fixes

High status but recovered file will not open: likely cause is hidden corruption beyond basic metadata; fix: try another version, compare previews, or test file repair after recovery to another drive.
Low status on recently deleted files: likely cause is overwrite activity, SSD TRIM, or damaged records after deletion; fix: stop writes immediately and rescan from the safest available state.
Unknown status for many files: likely cause is damaged file system data, formatting, RAW volume state, or incomplete metadata; fix: run a deeper scan and check previews where possible.
File name is missing or generic: likely cause is lost directory information; fix: sort by file type, size, date, and preview quality before recovery.
Video previews fail but file size looks normal: likely cause is codec limits, damaged headers, or missing media fragments; fix: recover a small sample first and check whether repair is needed afterward.

Quick Tips

A high recovery status does not guarantee a usable file. Preview and post-recovery testing still matter.
A low status may still produce partial data, especially for images, text files, or files with limited overwrite damage.
Unknown status is common on formatted, RAW, encrypted, or severely corrupted volumes where file system records are incomplete.
Clicking, disconnection, overheating, or read errors may indicate hardware damage. Continued scanning can increase risk.

💡Protip:

Use recovery status as a sorting guide, not a final answer. Preview important files and recover a small sample to another drive before exporting a large batch.
