Right.

When you invoke HARDPREP, just add "/secs:26" to the end of the command
line, and it will format and test RLL.....

Works quite nicely.  You WILL need to disable any on-board controller ROM(s)
if you are going to use Speedstor to handle the drive rather than any on-
board formatter which may be included on the controller.
