Update your archive software to the latest version. Just do as follows:

Step 3. Wait for the scan to finish, and then restart your computer if necessary.

Method 4. Check Storage Device Health to Fix Corrupted ISO Files

Your ISO files stored on an external storage device or a USB flash drive may be causing these ISOs to get corrupted. The steps you should follow include:

Step 1. Copy the ISO file to another media storage device, such as your computer's internal hard drive.

Step 2. Run a disk check on the problematic storage device.

Step 3. If possible, try to read the ISO file on another computer to verify if the problem lies with the file itself or your system.

Preventive Measures to Avoid ISO Corruption

In order to minimize the risk of future ISO file corruption:

• Always use a stable internet connection to download big files. Safely ejecting external storage devices before disconnection.
• Perform regular Antivirus Scans to prevent Malware Infections
• Make sure to keep important ISO files on multiple media.
• Verify downloads with provided checksums, where available from the source

Conclusion

Perform repair on those files that are irreacquirable or have important unique data using specialized software such as EaseUS Fixo. If you are having issues with multiple files, not just the ISO, consider using system-level utilities to resolve them.

For critical ISO files that will not open with simpler techniques, professional file repair software is generally the best bet for recovery, as it directly targets file structure corruption. If problems persist with additional ISO files, this could signify an underlying problem with your storage device or operating system and may warrant further analysis.
