Abstract: The invention provides a remotely-operable tester, designed to test multiple disc drives utilizing different interfaces simultaneously. The tester performs tests essentially similar to those performed by the manufacturer, and so is capable of accurately diagnosing disc drive problems without requiring the return of suspected defective disc drives to the manufacturer. Testers are attached to a local computer, which controls operation of the testers and communicates test results via a network connection to one or more other networked computers. The tester is capable of regulating power supplied to the disc drives under test, and of regulating the temperature within the tester. Each bay of the tester may be configured to support a different disc drive interface, and a drive initiator card attached to each bay supports disc drive interface formats needed for the various possible bay configurations.

Abstract: The present invention provides a portable on-site tester to test a disc drive at a location remote from the disc drive manufacturer. The tester supports multiple disc drive interfaces by supporting multiple drive initiator cards, one of which is selected for use at a time. A tester which controls operation of the tester is attached to a local computer via a tester interface. The proper drive initiator card is selected for connection to the tester interface such that the drive initiator card supports the disc drive interface format of the disc drive to be tested. The tester may be configured to support different disc drive interfaces by connection of various drive initiator cards to the tester. The drive initiator cards are mounted to one or more drive initiator card supports, which are oriented in the tester such that the selected drive initiator card is electrically connected to the tester.
