I'm having trouble copying files to an external harddrive in Windows 10. Using the same external harddrive on a Windows 7 PC works fine. Ports on the laptop that is having issues are USB 3.0 and I've removed and reinstalled the driver for both the USB controller and the external HDD. These are relatively large video files around 1.5 GBs in size, and I am able to copy FROM the drive OK, but trying to copy TO (copy -> Paste in Windows Explorer) the transfer will potentially start, then slow to 0 KBs and then eventually fail with Error 0x8007045D: the request could not be performed because of an I/O device error. The external harddrive then locks up and can only be reaccessed by removing and reinserting the USB connector.
Now from advice on forums I have set the external harddrive to be accessed using the performance setting and enabled write caching on the device but still the transfers fail. Another suggestion was to use safe mode in Windows 10 which I tried and I was able to successfully complete the transfers here.
Therefore my question is how can I figure out what is causing the transfers to fail in "full" Windows 10 but to complete in Safe Mode?
TL;DR - Large file transfers TO external USB harddrive fail unless windows is running in Safe Mode. Why?
