Troubleshooting 
Microsoft updates 
Make sure you have the latest Microsoft operating 
system service packs and other Windows updates 
installed on your system before you try to troubleshoot 
a drive problem. These service packs are issued to fix 
bugs, add drivers, and enhance the security features 
of your system. See http://support.microsoft.com
 for 
details about how to install service packs and 
Windows updates in your system. Contact Microsoft 
Customer Service for information about obtaining 
these system enhancements if you don’t have Internet 
access. 
Drive does not appear on my PC 
Try the following solutions in the order listed: 
1 Check to see if the drive is on. The power LED on 
the front of the drive and the light on the power 
adapter should be lit. 
2 Make sure the power adapter is securely plugged 
into the drive and into a power outlet. If the drive is 
plugged into a power strip, try plugging it directly 
into the wall outlet. 
3 Check that the USB cable is securely and properly 
connected to the drive and the USB connector on 
the PC. 
4 While the PC is turned on, unplug the USB 
cable. Wait 10 seconds and then reconnect 
the USB cable. 
5 See if the PC is recognizing the USB port you are 
using by checking in the Device Manager window. 
See the documentation that came with your PC for 
more information. 
I got a message that I have a 
high-speed device connected to 
a low-speed port (Windows XP) 
This is normal. Windows XP displays a message that 
you have connected your USB 2.0 drive to a USB 1.1 
port. You will not have the high-speed capabilities that 
you would have using a USB 2.0 port. 
 
I’m having data transfer 
performance problems with my  
USB 2.0 adapter card 
Your HP Personal Media Drive runs as fast as the host 
adapter card allows (up to the maximum burst rate of 
480 MB per second). If you are having performance 
issues, make sure that the USB 2.0 card drivers are 
the most current available and are installed properly. 
Software does not work or has 
stopped working 
Reinstall the software. See “Installing Drivers and 
Software from the Installation CD” on page 4.
