Lacie Hard Drive not recognised (Windows 8.1)

    Question

  • Hi, I am running Windows 8.1 on an Asus Ultrabook. When I attach a Lacie Hard Drive (HD) (runs off the USB power) it is recognised by the Device Manager, but not by the computer where I can run it and access the files. When I try and assign a letter to the HD it is greyed out in the options box in Device Manager. The HD software is up-to-date. I have tried different ports and cables, rescan, and uninstall options.

    I have tried this on a second lap top with similar results (Toshiba Satellite) running Windows Vista (Home).

    Any help appreciated,

    M

    2. You should format disk before using it. Go into Disk Manager and check if your disk is formated.

    3. Computer should provide adequate power. (Test HD in desktop computer.)

    4. New external disks are USB 3. Legacy interface need not work correctly.

    I second that. Most come with a power cord, I run a LaCie big series with thunderbold on a msi socket 1155, 17 GD80 military class MB.

  • instead of device manager, try disk management (create and format hard disk partitions)

    disk management should show you the drive, and the status of any partitions/volumes. you can also use disk management to re-assign drive letters if needed.

  • Hi,

    Also, diskpart is another tool to try:
