Windows 10: BSOD when transferring to external hard drive/USBs, windows 11

HelloI've just updated my PC to Windows 11. If I try to copy any file to an external hard drive or flash drive I get the blue screen with stop code : System_Thread_Exception_Not_Handled.This only happen when copying from the PC to the hard drive. It's ok to copy from the hard drive to the PC. I have tried multiple hard drives and USB sticks via the USB port and also via a dock.When I run in Safe Mode there is no issue. I cannot work out what is causing the problem. Grateful if someone can help resolve this. Please let me know what additional info you require.Thanks

:)

 

External hard drive not recognised

Thanks for this. I've done what you suggested and been through all the steps mentioned in the article. The hard drive works fine on a Mac computer, and I've managed to copy the information on it. It must be a Surface issue so I'll try to get a chat line tomorrow.

 

USB transfer speed from external hard drive to external hard drive

Transfer speed is dependent on the 'Read' speed from your old hard drive as well as the 'Write' speed to your backup drive. Normally these should be quite fast but if there is a problem with either drive then this could slow down transfer speed a lot and 150 KB/s is so slow as to point to a problem somewhere along the transfer path.

I suspect your drives are HDDs, not SSDs, but I get 305 MB/s transferring between two external SSDs connected to two USB 3.1 ports. This is over 2000x faster than your transfer speed so I suggest you run CHKDSK with repair switch on both drives? See https://docs.microsoft.com/en-us/win...ommands/chkdsk

 

External hard drive not recognised

Hi twynog,

The issue that you're experiencing with the external hard drive might be due to some missing Windows hardware or software updates. To help you in resolving this, you may follow the steps below:

Method 1: Uninstall and then reconnect the external hard drive - this method resolve issues where the currently loaded USB driver has become unstable or corrupt.

• Select Start, type Device Manager in the Search box.
• Select Device Manager from the returned list.
• Select Disk Drives from the list of hardware.
• Press and hold (or right-click) the USB external hard drive with the issue, and select Uninstall.
• After the hard drive is uninstalled, unplug the USB cable.
• Wait for 1 minute and then reconnect the USB cable. The driver should automatically load.
• Check for the USB drive in Windows Explorer.

If method 1 doesn't work the way it should, you may proceed to other steps provided in this
