The parameter cloning file on the MMC-PS exists but its contents are corrupt or invalid, specifically affecting the control word data. This prevents the drive from correctly loading parameters, potentially leading to incorrect operation or failure to start due to an invalid configuration.
Click steps to track your progress.
Recreate the parameter file on the MMC-PS by performing a new parameter save operation from a known-good drive configuration.
If the file was created externally, verify it was generated using the correct software version and drive model utility.
Attempt to format the MMC-PS card (e.g., using a PC) and then copy a fresh, verified parameter file onto it.
Check the parameter file size and compare it to previous working files to detect any truncation or incompleteness.
Use a different MMC-PS card, then copy the parameter file to it and re-attempt the cloning process.
