1476349 2021-04-13 01:06:00 Win 10 setup on desk top. PC recognises most of my external drives but not two. Device manager sees them and says they are working properly but they do not show on the pc screen so I can not open them.
What can I do?

In Search type in Disk Management - Select "Create and format hard disk partitions"

10861

Locate the External Drive, if it doesn't show a Drive letter, right click the Drive - Change Drive letter and Drives - Give a Letter - Save.

Should now show if this was the problem.

What can I do?

more info needed
USB Hard drive, USB stick ?
Are any Mac or Linux formatted
how old , when last used .
Powered USB drive ? if so is the power pack OK ?
Are they spinning up OK ? Any strange noises (put you ear against it )
could be as simple as a bad or too long cable .

Do you need the data on them
It often means they have some sort of fault , or have not been formatted (win compatible formatted)
If you need the data , then its a data recovery process

If you dont need the data, diskpart, clean , initialise & format
run a HD test program across them (WD has one thats easy to use)

1476353 2021-04-13 07:06:00 The powered external hard drives both work on my laptop and another pc. The problem is with my pc. Are they showing drive letters like I suggested you look at ?

"IF" for some reason there's not a drive letter assigned automatically they will show as you described but wont show normally.

Had this EXACT problem last week, plug in a USB drive makes all the connection noises, showed in Device manager but that was the only place. If the Computer was rebooted while the external was already plugged in worked fine.

1476355 2021-04-13 21:37:00 If there are no drive letters --- The above link seems to be a bit unstable. So here is what it suggests
Method 2: Auto mount.

Tap on the Windows key on your keyboard.

Type: command prompt

In the search results list, right-click Command Prompt, and then click Run as Administrator.

When you are prompted by User Account Control, click Continue.

Type the following commands.

Diskpart

Automount (This command will tell you, if it is enabled or disabled.)

Automount enable

Automount scrub (If automount is already enabled, type this command to clear the saved associations of system drive letters.)

Lastly type: Exit

Restart the computer and plug in the USB now to check external USB drives.

Then again it could be something completely different on the PC, but pay to check the basics first.
