The Write With Retries Operation
A new type of operation is implemented in WITE32 revision 3.11: the Write With Retries operation. This is a special
case of the write operation when the RWA shuts down the write gate in the sectors, in which the spinstand detects
that the Position Error Signal (PES) exceeds the specified tolerance. The software can repeat attempts to write the
failed sectors until the specified percentage of the sectors is successfully written or the maximum number of attempts
is reached.

that the Position Error Signal (PES) exceeds the specified tolerance. The software can repeat attempts to write the
failed sectors until the specified percentage of the sectors is successfully written or the maximum number of attempts
is reached.
The spinstand generates a signal indicating that the Position Error Signal is within the specified tolerance. The PES in
Tolerance signal is provided to the Scope Point 7 output of the spinstand control box.
Tolerance signal is provided to the Scope Point 7 output of the spinstand control box.
In order to use the Write With Retries operation you must connect the Scope Point 7 output to the Index In input of
RWA using a BNC-to-BNC cable, and check the Enable “Write With Retries” Operation check box in the
Measurement Options dialog box (click the Configure | Measurement Options…menu item of WITE32 Engineering
Dashboard to open the dialog box).

Note:
Never connect the Scope Point 7 of the spinstand control box to the Index In connector of RWA before you enable the
Write With Retries Operation check box. If you do not enable the check box, the spinstand Control Box will provide the
Position In Tolerance signal to the Index In connector of RWA, and WITE32 will not perform RWA initialization properly due
to incorrect index signal.
