WD Quick Tester Database
The database is a flat file structure used to store test data from each
drive tested, up to 100 test records. It provides the user a simple way
to store information and upload the data to a computing device for
processing. The tester does not allow for viewing of data once stored.
The Serial Data Port
As defined in the Utilities section on page 9, the Tester outputs its test
database to the RS232 serial port. The data is in the form of
comma-delimited records separated by a carriage return, line feed
sequence. The data is sent out ‘blind’ (no handshaking).
