Driver Signing warning using pre-installed proprietary USB storage drivers

The message regarding "damage my system because it is not a Microsoft product" does not refer to the Centon hardware.  It is referring to drivers already installed on your computer from your computer manufacturer.  Some computer manufacturers installed their own non-Microsoft set of drivers for USB Mass Storage devices on mostly Windows XP systems.  Generally it is safe to use those drivers.  You should be able to find more information from your computer manufacturer regarding this issue on their support pages, or by contacting their support team.

In general, the Microsoft drivers for USB Mass Storage devices are stored in the C:\WINDOWS\SYSTEM32\DRIVERS folder.  USB flash drives require the usbstor.sys among other files.  The following procedure may assist in restoring Microsoft signed (i.e. official) drivers, versus any proprietary driver that may have been installed on your computer.

  1. Select Search and then For Files or Folders.
  2. Search in All files and folders and also tell it to Look in: the C: drive.
  3. Search for the file driver.cab.
  4. If the file is found, it will tell you in which folder it is located. Write down in which folder it is located, such as C:\WINDOWS\Driver Cache\i386
    If the file is not found, insert the Windows installation CD.
    1. Open the Start menu in Windows.
    2. Select Search and then For Files or Folders.
    3. Search in All files and folders and also tell it to Look in: the CD/DVD drive.
    4. Search for the file driver.cab.
    5. Write down in which folder it is located on the CD.
  5. Connect the external drive. The Add New Hardware Wizard should appear.
  6. Indicate the location of the driver that you just found, and complete the Wizard.
