Returning the

If you must return your HD Drive to effect repairs or upgrades, use
the following steps:
1. Get the serial number and the model number of the defective
unit, and a purchase order number to cover repair costs in the
event the unit is determined by the manufacturers to be out of
warranty.
2. Before you return the unit, have someone from your organisation
with a technical understanding of the equipment and its
application include answers to as many of the following questions
as possible:
• What is the extent of the failure/reason for return?
• How long did it operate?
• Did any other items fail at the same time?
• What was happening when the unit failed (i.e., installing the unit,
cycling power, starting other equipment, etc.)?
• How was the product configured (in detail)?
• What, if any, cables were modified and how?
• With what equipment is the unit interfaced?
• What was the application?
• What was the system environment (temperature, enclosure,
spacing, unit orientation, contaminants, etc.)?
• What upgrades, if any, are required (hardware, software, user
guide)?
