External Hard Drive not showing in my computer

    Question

  • I have an external hard drive that im trying to connect to my computer with usb2.0 and it doesn't show up in my computer.  I can see it in Disk Management and it says its Online but doesn't assign a letter to it.  I'm running Windows 7 Pro 64bit.  I have 2 internal drives.  I have tried assigning the backup drive to different letters and that doesn't seem to work.  Any ideas???

  • Hi,

     

    I understand that the external USB hard drive doesn’t show in Windows Explorer but detected in Disk Management.  To resolve this kind of issue, I would like to propose the following suggestions:

     

    1.     Go to Device Manager, uninstall the USB hard drive,  scan for the hardware change and let Windows automatically re-install driver for your device.

    2.     Open Registry Editor, navigate to the following item:

     

    HKEY_LOCAL_MACHINE\SYSTEM\MountedDevices

     

    Find if your device is registered and assigned a letter.

     

    As a work around, I suggest you accessing the external hard drive via a Command Prompt, copy out the data, then format the hard drive.

     

    1)    Click Start, type: cmd in the Search bar.

    2)    Right Click cmd and click Run as Administrator.

    3)    Type the following command:

     

    Copy [source] [destination]

     

    Best Regards

  • It's a drive from another computer that crashed, and I would like to get the data off it.  Also when I right click on the drive the only option I have is Delete Volume.

  • I'm not sure I understand.  The enclosure supplies the power to the hard drive.
