Introduction

Modifications

The maximum track number limitation for Guzik S-312MP, S-1701MP, S-312MPCF, S-1701CF, and S-1701A spinstands was changed. New limitations are:

            Spinstand model             Maximum track number limit
              S-312MP, S-1701MP                 190 000

              S-312MPCF,S-1701CF,               399 992
			  S-1701A
            

1. A warning pops up when user selects a device driver in the Product Configuration Menu dialogue box and opens the Edit Driver Parameters dialogue box first time. The warning says "There is no XXXXXX.ddt file for chosen device. Default settings will be used.", where XXXXXX is a name of device selected. The default .ddt file is created in the product folder.
2. The Import button was removed from the Product Configuration Menu dialogue box.
3. The Align Range to Servo Offsets option was added to the following offtrack tests: the WROffset Test, the Triple Track Test, and the Off-Track Performance Test. The functionality of this option is similar to the Align Range to Servo Offsets option in the Track Profile Test. Please refer to the WITE32 Servo Option User's Guide for more details.
4. Eight new HDE files for head amplifier support introduced in the WITE32 ver. 2.42:
   • TDA5160.HDE,
   • TDA5362.HDE,
   • WILLOW4E.HDE,
   • CXA3096.HDE,
   • CXA3533.HDE,
   • SR1711.HDE,
   • SR1750.HDE,
   • VM5431.HDE.
5. The Info | EEPROM Dump. menu item was introduced in the Spinstand Alignment Program (WDCP). The dump contains information on the revisions of boards, installed in the spinstand. To invoke the EEPROM Dump dialogue box from WITE32, user opens the Configure | Device dialogue box, presses the Run Alignment Program button and selects the Info | EEPROM Dump menu item in the main menu of the Spinstand Alignment Program. The EEPROM Dump dialogue box appears:
   
   
   The Print button sends the EEPROM information to the printer.
   The Close Button closes the EEPROM Dump dialogue box.
   Note: the EEPROM Dump information is available for S-312MPCF, S-1701CF, and S-1701A spinstands only.
6. WITE32 main help entry.
   WITE32 help is now available in the WITE32 Engineering Dashboard. In the previous versions of WITE32, the Help | Contents and Help | Obtaining Technical Support menu items were disabled.
7. The default value for the Enhanced Performance Mode option.
8. The default value for the Enhanced Performance Mode option in the Configure | Test Options dialogue box changed to 'Enabled'. The default setting is used when you create a new product.
9. Quasi-regular pattern support for digital timing asymmetry test
   If customer creates quasi-regular patterns (like 1001000010010000....), he can use such patterns for digital timing asymmetry measurements with RWA-2585. In previous versions of WITE32 only regular patterns were supported (like 10101010....).
10. New option in the Control | Scope Point dialogue box.

1. The PRML chip settings are corrupted after the Spinstand Alignment Program is closed or WITE32 External Module is unloaded.
2. The "PATFILE: Multiple definition of pattern PCLBLD" error message pops up in case of VENOM PRML chip installed.

1. The Pulse Profile test is sending six values to result stream as configuration parameters, not as result values. The values are: TAA Pos, TAA Neg, TAA Both, PWN Pos, PWN Neg and Base Shift. Now these values are reported as results.
2. Even when the Aborted Result option in the Configure | Test Options dialogue box is disabled, results are still displayed if a test is aborted by user.
3. The WITE32 Result Processor displays an "Automation Error" message at the end of a test if a test module defines its result names using high ASCII code (i.e. ASCII character with code higher than 127).
4. The Failures dialogue box displays "Subscript out of bound" error message if there is no grade defined.
5. If user clicks the Cancel button on ASCII export in the Result Processor output window, the Save As. dialogue box pops up 3 times.
6. The failure records in production are not printed if user clicks the Print! menu button in the Result Processor output window.
7. If user clicks the No button for saving configuration in the Result Processor output window, changes are still saved.
8. The result name of Spectral SNR test is changed from SNR to SpectralSNR to avoid the name collision with regular SNR test.

1. The Operator Panel (production mode) hangs up after the Select Head test is started.
2. The Operator Panel (production mode) starts device for configuration-only tests (Select Head test, Normalization test, Grading test). Now configuration-only tests do not start the device.
3. The Test buttons in the Operator Panel do not have shortcuts.

1. In case of Individual head amplifier power control option enabled, head amplifier loses properties after switching heads.
2. For Guzik head amplifiers read bias current -1 mA is unacceptable, causes improper behaviour.
3. The Read Only Parametric test now reports TAA with current sensitive head amplifier in milliamps (mA), unless the Convert results to mV option in the Configure | Preamp dialogue box is selected.
4. Numerous head amplifier power on/off transitions on WITE32 startup and start device operation.

1. RWA-1601/RWA-1632 models feature special index-to-index write gate mode. This mode is supposed to be enabled when write gate is set to Full Size in the Gate and Track Format dialogue box. In previous versions of WITE32 this mode was enabled only after the Gate and Track Format dialogue box is opened. New version turns this mode on immediately after WITE32 start.
2. The "Index inside counting gate" message pops up in the Popcorn test for RWA-1601/RWA-1632. The message pops up during execution of popcorn test for some setups if the Check for extra pulses option is enabled.
3. An Automatic Equalization procedure does not work for RWA-1632 PRML because of missing CHOPPRF pattern definition.

1. Incorrect sequence of warnings after the Track Size and the ID Radius parameters modification in the Configure | Device window.
2. The Triple Track, Track Profile, Head Polarity, and the Monitor Production test configuration is not shown in the File | View Configuration. dialogue box.
3. Some tests, which do not have a configuration, trigger error message in the File | View Configuration. dialogue box (e.g. Write Pattern, Servo ON). These tests were removed from the list of tests available for configuration review.
4. WITE32 intermittently hangs up during zone/setup deleting.
5. The Cancel button in the Configure | Identification dialogue box does not cancel changes.
6. It is possible to delete or change order of three required (default) identification fields (Operator ID, Station ID, and Part ID) in the Configure | Identification dialogue box.
7. The field editing is activated if you press the Up or Down buttons in the Configure | Identification dialogue box.
8. It is possible to put an improper value (for example, zero) for the Increment of Erase Current Range (mA) parameter in the setup of the Low Erase Current, the Critical Erase Current, and the Multitrack Critical Erase Current tests (WGMA module).
9. The Alternate Spectral Elimination test configuration dialogue box prompts for saving configuration on exit, even if user did not modify any settings.

1. Zone/setup dependent servo parameters in the opened Servo Calibration dialogue box are not updated when user changes current zone or setup.
2. If the Restart button is pressed in the WITE32 Engineering Dashboard while device is started, the head does not return back to the original track after restart is completed.
3. The MR-Impedance test does not work properly with UP6 rev. 1.1.
4. When you look at the Raw Read Data signal at scope point 1 and scope point 2 (2550/2585 only) and then open the Control | Clock dialogue box, signal disappears.
5. Head Polarity test does not work in sector mode.

Note: In new version of WITE32 this test does not need the special HDPOL.EPT pattern file anymore.

6. If user clicks the Cancel button in the production serial number input menu, the start of write gate will begin at index, rather than some delay after index.
7. If the Gated Stability option was disabled and the Write Option set to None in the PWN Stability and Amplitude Stability tests, those tests perform the Erase operation and run measurements on the erased track.
8. External OCR (Optical Character Recognition) support does not work if production test is started from the WITE32 Engineering Dashboard.
9. An Automatic Equalization procedure (accessible through the Calibration | Auto Equ. menu item) hangs up in standard WITE32 configuration.
10. It is possible to run WITE32 on an RWA model other than model, specified during installation of WITE32 (for example, running WITE32 RWA-1601/1632 on the RWA-2550/RWA-2585 causes an avalanche of meaningless error messages).
11. Missing TSTTRKPROF2 DLL entry point when running custom tests using WDK32. This bug was introduced in WITE32 ver.2.40 release.
12. Uninstallation of WITE32 does not remove all installed files and Windows registry entries.
