WITE32 Release Notes Version 3.20
4. WDCP crashes after the following sequence of actions:
• Select Head Stack check box in the Spinstand Parameters dialog box (Parameters | Spinstand
Parameters… menu item of the Spinstand Alignment Program WDCP).
• Press Save Data in EPROM button.
• Close WDCP and reset spinstand.
• Run WDCP in standalone mode.
5. For 1701 family Spinstands pressing the Optical / Zero Angle button does not allow to start Manual
Zero Angle Alignment when is not possible to perform Video Alignment.
5.3 Servo
1. The Servo Calibration procedure can be run even if the Servo Area check box in the Gate and Track
Format dialog is disabled. In this case the procedure fails, but changes the system Read and Write
gates.
2. In the Servo Erase operation, only the DC positive and DC negative selection in the erase direction are
executed correctly. The other selections use wrong direction for erasure.
3. It is impossible to open Zone/Setup editing from the Servo Calibration dialog box after modification of
any Servo Calibration parameters unless the Save Setup button is pressed.
5.4 Analog Front End
1. TAA calibration factors are not updated in the Calibration | TAA… window if a zone/setup is loaded
where TAA calibration has never been performed.
2. If a test sets head amplifier properties before starting device, the head amplifier properties are not
loaded along with other zone/setup parameters.
3. The Calib TAA operation included in the Production test intermittently returns wrong coefficients when
run in servo mode with UP7.
4. If two current sensitive head amplifiers are installed, TAA measurements return wrong results if TAA is
converted to mV. That is the Convert results to mV option in the Configure | Preamp dialog is enabled.
5. WITE32 does not measure MR-Impedance to use for TAA conversion from µA to mV after the head is
changed. That can lead to not proper TAA result for the new head.
6. In the case of the Multiple Headstack front-end configuration is installed, the Reload button in the
Control | Head Amp... dialog box does not load a driver selected from a list. The current Head Stack
driver is reloaded instead. The Reload button is disabled in the current revision of WITE32 for the
Multiple Headstack front-end configuration to avoid confusion.
For the Multiple Headstack front-end configuration you can select a Head Stack driver from the HSA Driver for T-
Shape Board list box in the Configure | Preamp dialog box.
