How can I suppress the error message generated if my ZIP drive is not connected?

A. A. This is a function of the Iomega Zip service (PPA3NT, obvious name!) and error announcement can be disabled by performing the following:

1. Start the registry editor (Regedit.exe)
2. Move to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\ppa3nt
3. From the Edit menu select New - DWORD value. Enter a name of ErrorControl and press ENTER
4. Double click the new value and set to 0.
5. Close the registry editor
6. Reboot the machine for the change to take effect
