Additional required software for USB drive.
===========================================
  - Install the tape driver for LTO when a USB drive is connected and powered on.
    The first time a USB drive is connected and powered on, the USB drive is shown under
    "Other devices" in Device Manager. Then, the tape driver for LTO is required before using LTFS.
    To install the tape driver, follow the steps below.

  Procedure
    1. Unzip LTOUSB_IBM.zip
    2. Open Device Manager
    3. Choose the USB drive under "Other devices"
    4. Right click the USB drive and choose "Update Driver Software..."
    5. Choose "Browse my computer for driver software"
    6. Choose "Let me pick from a list of device drivers on my computer"
    7. Choose "Tape drives" and click Next
    8. Choose "LTO" in Manufacturer and "LTO Tape drive" in Model, then click Next
    9. You may see a warning message. In this case, click Yes to install the driver

  NOTE: Even if you install the tape driver, when you unplug the USB drive and plug it
        to another port, you need to install the tape driver again. If you do not see the drive
        in the Configuration panel, you need to confirm the driver is installed by Device Manager.


Hint and Tips for USB drive.
===========================================
  - DO NOT unplug/powered off while a drive letter is assigned.
    Before a USB drive is unplugged/powered off, the drive letter should be unassigned.
    If you unplug/power off the drive while a medium is mounted, the medium may become inconsistent.
    In this case, you cannot access to the medium even if you plug/power on the drive again.
    To have access, follow the steps below.

    Procedure
      1. Unplug the drive.
      2. Right-click the LTFS icon to display a drop-down menu, and then select Eject.
      3. You might see an error dialog (LTFS60201E). In this case, click OK.
      4. Unassign the drive letter by using the Configuration panel
      5. Plug in the drive, and then power on.
      6. Assign a drive letter by using the Configuration panel.
      7. Check the LTFS icon. If the data has inconsistencies, recover it by following these steps:
        7-1. Open a Properties panel by right-click the LTFS icon and choose Properties
        7-2. Click Check to begin check and recover operation.

  - Eject a medium before your computer goes into sleep or hibernate mode.
    If the computer goes into sleep or hibernate mode while a medium is mounted, the medium might
    become inconsistent.
    In this case, you cannot access the medium after you wake the computer.
    To have access, follow the steps in the procedure above.

    When you wake the computer and insert a medium, you might see that LTFS does not start mounting.
    In this case, the icon is kept as a drive to represent that the medium is not inserted. And, the
    configuration panel shows two lines for the drives. One is assigned to the drive letter, and the
    other is not assigned, but shows "Not applicable" in the "State" field.
    To start mounting, unassign the drive letter by using the Configuration panel,
    then assign a drive letter again.


  NOTE: Your computer might have a setting to go into sleep or hibernate mode automatically.
        In this case, it is recommended to change the setting to not go into sleep or hibernate
        mode automatically by adjusting the Power Options in the
