I have had that same problem with my B450 Aorus Pro Mainboard and also with my current MSI X570-A Pro mainboard,
Everytime i connect my external HDD to an USB 3 port, it looks like this picture attached.
When i use Ubuntu or any other Linux for an example, i have no issues using the HDD with USB 3, I feel like the USB Driver for Windows 10 in the chipset is not working :/
Does anyone know how to fix this?
In Device Manager, in the image, is that with your External Intenso Memory Drive connected to a USB 3.0 port or USB 2.0 Port?
According to Intenso's Manual you need to use the supplied USB cable that came with the HDD when you purchased it.
If you are using a different USB cable then the one that came with the external HDD maybe that is why you are having problems in Windows.
Also when you connect it to the USB 3.0 port does the HDD LED light up showing that it is getting enough power?
What does MyPC show when connected to USB 3.0 port?
Can you run diagnostics under "Properties" - "Tools" when you right click on your external HDD in MyPC?
In your Motherboard's UEFI/BIOS can you configure the USB 3.0 ports and if one of the USB 3.0 settings will help make your external HDD compatible?
The manual mentioned if the USB port doesn't have enough power to run the Ext. HDD to plug it in a USB Hub that has it own power. See if Windows recognizes and shows it compatible?
I am using the Original Cable it came with :/ When i connect it to the USB 2.0 it lights up green, and when i connect it to the USB 3.0 Port it lights up Blue. MyPC Shows it as Local Disk H: but when i try to access it, it freezes, i can Access it in MyPC when i use USB 2.0.
i cant run diagnostics sadly because it endlessly loads :/
i can check later in the UEFI if theres any option for USB 3.0
Windows recognizes the HDD and all, and MyPC shows it too but i can't access it, i managed to fix it once but i forgot how i did it :/
It says This device is working properly. :/
Then this suggests your windows setup is corrupted
you can reset windows and save personal files and you will have to install drivers and apps fresh
From what I have read about Intenso external HDD they use a Toshiba HDD in a Intenso exterior case.
Seems like your Intenso ext. HDD came formatted in FAT32. Did you by any chance format it to a different format like NTFS? If you did, format it back to FAT32 and see if it is compatible now with USB 3.0.
I suggest you contact Intenso Support to find out if your HDD is defective: Contact | Intenso
Its not the HDD or the whole thing, its Windows drivers, it works fine on Linux but it doesnt on Windows, it works fine with a system using AM3 and Intel though.
Its only the AM4 that causes this problem
