WITE32 Release Notes Version 3.20

CHAPTER 1

INTRODUCTION

The release 3.20 of WITE32 incorporates the new features and the bug fixes introduced after the release 3.11.

This document uses the release notes for the WITE32 version 3.11 as a base line for a comparison.

1.1 Updated PRML Chip Drivers

With the WITE32 version 3.20 you must use only the version 3.20 of the drivers for RC6600,

88C7500P PRML channels (Chip Adapter 2000 board), and 88C7500M PRML channel (Chip

Adapter 4000 board). These new drivers are shipped on a separate CD. Please contact Guzik

customer support to request the drivers.

Note: Do not install any previous versions of the RC6600, 88C7500P, and 88C7500M chip adapter drivers when you

already have installed the WITE32 version 3.20. The obsolete drivers will overwrite the WITE32 version 3.20

modules, and make your installation inconsistent.

1.2 Updated Revision Numbers of Head Amplifier and Head Stack Drivers

In WITE32 version 3.20, the Guzik head amplifier and head stack driver revisions are updated from 3.xx to 4.xx,

where xx is a two-digit number. If WITE32 version 3.20 detects a head amplifier or a head stack driver with

revision 3.xx, it displays an error message (see Figure 1). When you install the WITE32 version 3.20, the Guzik

drivers with updated revision numbers automatically substitute the Guzik drivers with the revisions 3.xx. The

driver replacement does not require any additional actions except the cases described below:

• If WITE32 displays the error message (see Figure 1) “HDL: The old revision of Head Amplifier driver is

detected. Please contact a Customer Support department of your Head Amplifier manufacturer to get the

newer revision of <driver name>”, you must contact the driver manufacturer and request the driver with the

updated revision number.

• If you use a Canon spinstand with Canon head amplifiers, contact the Canon Customer Support department

to request an updated driver.

• If you designed your own head amplifier driver or head stack driver, and the revision number of this driver

starts with digit 3 (revision 3.10 for example), you must change this first digit to 4 and recompile the driver.
