4. Frequently Asked Questions
Q1: What is USB 2.0 Hi-Speed?
USB 2.0 features transfer rates of up to 480Mbits/sec, a dramatic increase of 40 times over the speed of
USB 1.1. USB 2.0 Hi-Speed preserves the USB 1.1 ease of use, plug and play, driver auto installation
and power management features. USB Hi-Speed is fully forward and backward compatible with USB
1.1 allowing the use of USB 1.1 devices and cables with USB 2.0 host controllers.
Q2: Why do I get less drive capacity than reported on the package?
Your drive’s reported capacity will always be less than the capacity mentioned on the package. The
accepted drive industry standard reporting capacity uses 1000 bytes per 1KB, i.e. 10GB = 10,000,000,000
bytes. However, operating systems use 1024 bytes per 1KB, i.e. 10,000,000,000 bytes = 9.5GB. So, your
operating system will always report the capacity in GB to be less than the drive rated capacity. Also,
some capacity is used up for overhead.
Q3: Can I plug in USB Hi-Speed Drive into USB 1.1 ports?
Yes. However, it will only run at the maximum speed of USB 1.1.
Q4: Can I use USB Hi-Speed Device at the same time with USB 1.1 devices?
Yes. USB Hi-Speed devices can coexist with USB 1.1 devices.
Q5: Can I use this device with OS 9 & OS X?
Yes. You must make sure you have a USB 2.0 card installed and driver loaded, so that you can take
advantage of USB 2.0 speed.
Q6: Should I update my driver?
Yes, it is a good idea to always keep your drivers up to date. It is a good idea to check Microsoft’s
Windows Update website at http://windowsupdate.microsoft.com or Apple’s website at http://www.
apple.com/support for USB driver updates.
Q7: The device cannot be detected or is disabled (have yellow exclamation point next to the device
name under the USB section in the Device Manager). What can I do?
Please make sure you are logged in as the Administrator or a user with Administrator privileges in
Windows in order to install new hardware and driver. Unplug the drive and then plug it back into the
system. If you still see the yellow exclamation mark, first click on the device with the yellow exclamation
point next to it to select it. Click on the Action menu at the top and choose Uninstall. Then click on
Action menu and choose Scan for hardware changes to reload driver. Also please try upgrading your
USB 2.0 PCI card or motherboard USB drivers.
Q8: Why does Windows keep asking for a driver when I plug the drive into a different USB slot or
when I plug it through a USB HUB?
Windows keeps track of your hardware device IDs and capabilities in the registry. Every time you
change a device or slot, Windows goes through the installation step again. Please go back to look at the
installation instructions.
