Technical Support Wizards
If you are connected to a drive via DriveExplorer™ or DriveExecutive™,
you can run a Tech Support wizard to gather information that will help
diagnose problems with your drive and/or peripheral device. The
information gathered by the wizard is saved as a text file and can be emailed
to your remote technical support contact. (See
Call Tech Support on page 3-13
for more information.)
To run a Tech Support wizard in DriveExplorer, select
