Windows 10: Win 10 2004 External Hard disk not recognized

Last week I got windows update to 2004 version. It showed up as optional update so i updated it. Everything was running OK, so i thought to keep the update. I realized yesterday that my external hard disk was not being recognized by windows anymore.

I have an WD Easystore 4TB harddisk using it for 2 years now. I normally use it with thunderbolt port type-C on my laptop. It shows up as USB3.1 device on my device manager and no problems with this. When i connect it to USB3.0 type-A port windows doesn't recognize it. It has 3 type-A port and none of the ports recognize my external hard disk, but it runs fine on my Thunderbolt port.

I have seen a bug in 2004 version regarding the storage spaces, but don't know if it is related to my problem. I don't have a RAID setup. My hard disk has NTFS file system. If anyone has experienced it or have any solution to it please let me know.

external hard drive not recognized

Hello zbook
#1) I have tested the external drives in three different computers, win10 pro, Win10, and XP. The results are identical. When I plug in the external hard drive windows signals a new device with an audio signal and the light comes on on the external drive. The results on all three pc's is identical in disk manager, file explorer and device manager.
#2) I have tried all solutions presented to me by FreeBooter, from the simplest solution of uninstalling the external drive in device manager and rebooting windows, to using the various third party software that was suggested, obviously with out success.
#3) The attached screen shots will only show one of the drives attached because I don't have enough free USB ports to attach two drives and I didn't think it would have been a good idea to use a hub.
#4) one strange thing about one of the drives is that now device manager lists it as a Toshiba drive although it is a Western Digital.
#5) Sorry but I have no way of getting a photo of BIOS










I look forward to reading your comments
