Hi,
This is my first time posting here. I've read many similar threads to mine, but have tried all the suggestions I can find and just can't find an answer to this problem.
I recently bought a new laptop running Windows 10 (a Lenovo Legion 5 Pro). However, it has developed a problem where I cannot copy large quantities of data (more than a few GB) between USB drives, or from the internal SSD to a USB drive. This problem occurs with any USB drive, regardless of type or formatting. Initially, the file transfer appears to begin successfully at normal USB 3 speeds for the drive type (and small file transfers are successful), however, after a while the speed begins to become unstable, then plummets down to just a few KB/s, then, most often, stops entirely, reaching 0 bytes/s and never increasing. I have tried a lot of things to solve this, but none of them have made any difference. These include:
I'd be really grateful for any suggestions anyone can give!!
Thanks.
Derek.

I have tried a lot of things to solve this, but none of them have made any difference. These include:
- Restart PC
- Unplug all other USB devices
- Quit Google Drive
- Disable antivirus (Bitdefender Free)
- Quit backup software (EaseUS Free)
- Try different USB drives (HDDs and flash drive)
- Try different USB ports
- Copy a different set of files.
- Read from external drive instead of write - seems to read fine, but won't write anything large
- Airplane mode
- Safe mode
- Disable Remote Differential Compression
- Disable Windows Search
- Try from a different user account
- Check Event Viewer - couldn't find anything that seemed relevant
- Check Task Manager and Resource Monitor - couldn't see any untoward activity
- Copy between two external drives - seems to be less prone to the problem than when copying from internal SSD, but not immune.
- Increase priority of Windows Explorer process
- Uninstall antivirus
- Disable Windows Defender
- Check for corrupt system files - checked and repaired by DISM and SFC
- Is compression switched on on external drives? - no
- Disable USB selective suspend
- Update system
- Run Chkdsk on all drives
- Uninstall Google Drive
- Update/reinstall drivers - updated via Windows Update with optional updates, reinstalled USB drivers
- Disable drive indexing
- Try 3rd party file copier - tried Teracopy: exactly the same problem
- Run Memory Diagnostics - no problems found
- Run Hardware and Devices Troubleshooter - nothing relevant "fixed"
- Check "Optimise Drives"
- Uninstall backup software
- Try a different drive format in external drive - tried exFAT (previously NTFS): same problem
- Test many small files vs one large - one large (~250GB) file causes no issues. Many smaller ones cause the problem to occur.
- Test network file transfer. This is what I'll try next.
- Installing another OS on a new partition and try testing it from there (just to rule out a strange hardware issue).
- Update to Windows 11. I might try this.
- System Restore. I'd really prefer to avoid this, as I've only just solved some major problems that I've been having with Google Drive, and this could cause more problems in that regard.
- Reinstall Windows from scratch. I'd prefer to avoid this to save all the work of reinstalling everything.
I'd be really grateful for any suggestions anyone can give!!
Thanks.
Derek.
