Hi Todd,
Could you share the model# of the disk and the link to the firmware file you used?
If the .fla file is not available for the model you are trying to update ( As they are being discontinued ), you would need to run the smart component, follow the on-screen instructions to complete the firmware update.
Do not extract the firmware file and load the .fw or any other files to the SMU.
Regards,
Rakesh S
