USB HDD Not Showing Up?

jumanji said:

automount Command : Enables or disables the automount feature. When enabled (the default), Windows automatically mounts the file system for a new basic or dynamic volume when it is added to the system, and then assigns a drive letter to the volume.

As it says, by default automount is enabled in Windows.

When none of your USB storage devices ( external HDDs, Flash drives) show up in Windows Disk Management (this can happen sometimes) , then we recommend to check whether automount got disabled - somehow. If disabled you have to enable it.

( If only one of your external storage device does not show up but others show up with drive letters, there is no need to check automount. That means there is a problem with that storage device. Just to confirm I wanted you to check it on another PC.)

Actually Steve C should have recommended this:

Start > All Programs > Accessories > Right click on Command Prompt and Run as administrator.
Then
diskpart [ENTER]
Against the DISKPART prompt
automount [ENTER]
Does it say "automatic mounting of new volumes disabled " ? Then
automount enable [ENTER]
"automatic mounting of new volumes enabled"
Close Command Window.
If "automount" command says ""automatic mounting of new volumes enabled" then there is no need to give the "automount enable" command.

Since you said that three of your external drives are working fine, the above exercise is redundant , but no harm. Sometimes redundancy does help.

I don't agree. I once had one external drive not appearing and automount enable fixed the problem.

You may disagree, it is your pleasure.

Automount is a generic command. It either enables mounting of all USB storage devices or disables mounting of all USB storage devices

There is no way one can mount enable or mount disable a specific USB storage device.

"I once had one external drive not appearing and automount enable fixed the problem." I don't believe it. It is my pleasure :).

Hi all,

I'm having a similar problem now so I didn't want to create a new thread.

I just plugged in a USB HDD and Windows 10 makes the "chime" noise when it's connected, but it doesn't show up in "My Computer" and I don't know why? How can I find it?

Thank you for any help!

I had this problem a couple of days ago. I opened the drive caddy and found the connection to the disk had worked loose. All was fine when I firmly reconnected the drive cable to the disk.

Can you post a screenshot of Windows Disk Management? Let us see whether that drive appears in it and if it does what it says (not initialised/ Unallocated/Raw or whatever else.).
