Hello all! HP Z230, latest build Win 10.
I have two external drives connected through USB 3 ports on the front of the box. Drive "F" (WD My Passport) has a large collection of music files. Drive "G" (Toshiba) is a file backup drive. They have worked perfectly for two years. Now the following happened. All of a sudden, neither drive was recognized. I went through all of the standard steps--reboots, reinstall of USB drivers, etc.No soap. I started playing with the drives. Now the "F" drive is correctly recognized and functions normally, although there was a lot of odd behavior at first, that went away after reboots and driver reinstalls. BUT if I also plug the "G" drive to any of the front ports, the "F" disappears and "G" is not recognized. BUT the "G" drive works perfectly if I plug it into the port on my monitor. I can build a machine from parts. I have solved many complex problems for myself and others. I can't figure this one out.
Possibly relevant. I had several older drive plugged into these ports with a SATA to USB setup to recover older files. This went okay. There have evidently been some MS updates regarding USB including the "Extensible Host Controller" and "Root Hub USB 3.0" (see screen grab) I suspect these.
