I upgraded my Windows 7 Dell desktop to Windows 10. I have several external hard drives attached, and two of them are Seagate USB 3 drives. Since the upgrade I've had problems with the drives dropping off. Sometimes I have to reboot and sometimes I can just go into Device Manager and uninstall and scan to get them back. Never had this problem with Windows 7, and no issue with the USB 2 drives attached. All drivers are up to date, and I've uninstalled / scanned for new hardware everything under Universal Serial Bus Controllers in Device Manager. Dell's tools as well as Seagate's tools claim my machine is up to date. Once reconnected, the drives will be okay for anything from several minutes to a couple days before one or both drop off again. Typical event log entry below. Not sure how to proceed with this.
