Hercules's CKD/CCKD Dasd device driver logic does not currently support the Write Full Track (WFT = X'95') or Write Track Data (WTD = X'A5') CCW opcodes.

The IBM Reference manual that documents these CCW opcodes is SA22-1025-00 ("S/390 Internal Disk Subsystem Reference Guide").

Thank you, Alex. Having a stand-alone test program would be very helpful.

I will contact you once I begin work on this issue.
