I would recommend updating your chipset/all in one drivers. I find that most often
windows updates break things then AMD releases a new driver package to fix them
again. ]]> Tue, 28 Apr 2026 19:49:02 +0000 https://forum.asrock.com/forum_posts.asp?TID=113501&PID=201303&title=b450-pro4-io-errors-on-external-hdds#201303 https://forum.asrock.com/forum_posts.asp?TID=113501&PID=201301&title=b450-pro4-io-errors-on-external-hdds#201301 Author: garagedrive

after applying KB5083769, USB3.0 external USB HDDs don't work properly. They often show I/O errors.
HDDs are safe. I've confirmed them connecting them to internal SATA ports.
I've also changed HDD cases, and the problem remains.
