HP Library & Tape Tools software provides free diagnostic and troubleshooting utilities. It

allows you to:
• Quickly identify, diagnose and troubleshoot drive and media problems.
• Verify that the drive is installed correctly and check drive health.
• Upgrade to the latest drive firmware (you will need internet connection to do this)
You can also install HP Library & Tape Tools from the link on the HP StorageWorks Tape

You may notice the internal identifier for the tape drive when you use HP Library & Tape Tools.

This is also the name that appears on the bootup screen for Windows users and is used to

identify the tape drive when configuring UNIX device files.

Performance Assessment Tool

Use our free Performance Assessment Toolkit, PAT, to check tape performance and test the

speed at which your disk sub-system can supply data.
