Troubleshooting

Verifying USB installation for optimum performance

Has a new operating system been installed in the host computer? Has 
new backup software been installed?

The problem could lie with the host or the software. Consult the computer’s 
operating manuals, the software manual, or seek help from a service engineer.

6.2

Verifying USB installation for optimum 
performance

To confirm that a USB DAT drive is installed correctly:

Ê

Check that a USB 2.0 port is being used.

Ê

Ensure that the tape drive is the only device on a USB hub.

Ê

Ensure that the hp_usbstor driver is being used.

6.2.1

Check for USB 2.0 port (Windows)

It is important to ensure that you connect your drive to a USB 2.0 port. The drive 
will work on a USB 1.1 port but performance will be severely degraded.

To check the port on a Windows system:

Ê

Go to Device Manager and select Devices by connection from the View 
menu.

Ê

Expand Universal Serial Bus controllers and locate the tape drive.

Ê

If a USB driver is listed as Enhanced, the port is USB 2.0.
