Troubleshooting guide
How to fix the problem
Stopping file copying may indicate read errors, a bad cable, or an unstable drive. If a copy of important data is not available, do not start with the repair, but evaluate what else can be safely saved.
Possible solutions
Choose the method that matches your situation. Start with the simplest suitable option and check the result. If the problem is fixed, you do not need to continue with the other methods.
Copying the most important files
Only suitable for a stable readable disc with no signs of serious mechanical failure.
Steps to follow
- Stop writing new files to the problem drive and don't run speed tests.
- Choose another healthy physical media with enough space and start with the most important small files.
- Copy in small clear groups. If one file crashes, don't force it to repeat multiple times, especially if the drive is deteriorating.
- Check the copied files on the destination drive. If all connections are lost or errors are increasing, stop.
External connection and health check
Do not correct reading errors with a write test.
Steps to follow
- After safely disconnecting the external drive, check for another suitable data cable and a direct USB port.
- If the drive is stable, review the manufacturer's diagnostic status information without running a destructive test.
- If media errors are displayed, consider having a professional sector copy done before chkdsk or other repair.
- Store the recovered data on another drive. Do not continue to use the problem drive as your only backup.
If the problem persists
If the drive disappears, slows down significantly, or makes unusual mechanical noises during copying, stop testing. For non-volatile data, professional recovery is better than repeating the same read or file system repair multiple times.
