My Computer Doesn't "See" External Hard Drives

[Hermitkrab]

Toshiba laptop, W10 Home, Ver 1803

I have 2 external hard drives. When I plug either of them into a USB port I hear the normal beep sound, indicating they've been recognized but they don't automatically play, even though auto play is enabled . They don't even show up in "this PC", as if they don't exist. Funny thing is, when plugged into my HP machine, running same OS, they show up OK. Both laptops are fairly new, so I don't know why the HP acts differently than the Toshiba. BTW, I'm pretty sure at one time the Toshiba was able to read the external drives OK. Maybe an update messed something up?

remove the usb controllers through device manager and then reboot. Similar thing happened on my system after a windows update.

How do I remove "USB controllers"? When I right click on it, I get no option for removal. Thanks.

Right click and uninstall.

Thanks, Msuk.
, I've got it working. I opened Disk Management and found the external drive there, but it had no letter assigned. I labelled it F, which was the original letter when it was working. I suspect a recent W10 update may have caused the glitch.

Does that ever happen? LOL

Yes had that also happen a couple of time. Just had it happen to my phone.
