    USB HDD Not Showing Up?


    Hey guys, I've got 4 external USB HDD's connected to my PC. 3 of them are working fine, however the 4th isn't showing up.

    It shows up when I right click the USB icon in the bottom right corner of my screen and its name is "My Book" but it doesn't have a drive letter like the other USB HDD's.

    Thank you for any help!

    To add to what Samuria is saying, go to Start/Search and type diskmgmt.msc, Right click the diskmgmt results and Run As Administrator. In the Elevated Disk Management window, in the lower pane, find your My Book external HDD, Right click it and choose Change Drive Letter or Paths. Choose a drive letter not being used.

    I had to put this USB hard drive away, but I'm going to try your idea now.

    By the way, if your idea doesn't work what else can I try?

    Thanks!

    I'm still unable to access this USB HDD.

    Does anyone have another idea?

    Thanks!

    EDIT:

    The USB HDD is plugged in, but it's not showing up in Disk Management...?

    Try this

    1. Open an admin Command Prompt window
    2. Enter DISKPART
    3. Enter AUTOMOUNT ENABLE
    4. Enter EXIT


    The reboot, reconnect the drive and see if it is recognised.

    Okay thanks, but could you explain what this will do and how it works?

    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.
