It allows you to test (exercise) basic functionalities of the drives (read/write/seek to track, etc.) without the use of a somputer and software. Particularly useful when trying to align drives, as many of the more 'intelligent' exerciser units have the 'standard' alignment track numbers pre-programmed. -jim --- jimw(a)agora.rdrop.com The Computer Garage - http://www.rdrop.com/~jimw Computer Garage Fax - (503) 646-0174
