Windows 10: External hard drive being recognized under 'disk drives' but not under 'storage controllers'I

Hi,

I'm using Boot Camp right now on a mac, and I don't have enough space to use the internal drive for downloads so I'm trying to use the external drives. I have a Toshiba USB 3.0 2 TB external drive, and while the system seems to recognize that I have a USB 3.0 plugged in, it can't recognize the drive. I went to my PC and the only thing I saw there is the bootcamp drive. What's the best way I can solve this, ideally without reformatting the drive?

:)

 

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
