What is the Inhibit driver loading option in ExpressPro-Tools, and when should I use it?
Inhibit driver loading stops the drivers installed on your hard disks from loading at startup. This option requires the
ExpressPro-Tools extension to be loaded in the system folder, this also requires ExpressPro-Tools version 2.3.2 or
later. This option can be helpful when using drives that are formatted with different utilities or if disk driver
problems occur.
