Thanks for your reply.

I'm not sure if Fusion drive is unfused or working as a Fusion Drive.

Disk Utility information about Apple SSD is unformatted and have more two Internal Drives.

System Information > Storage information I can only see one Internal Disk (1TB SATA Disk) and no mention to SSD.

Should I format my Hard Drive and fix it to to regain the benefits of having the single logical volume of a Fusion Drive as described in Apple Support page?: https://support.apple.com/en-us/HT207584

Thanks

To be honest I think you should take it to an Apple Authorized Service Provider, someone that knows what they are doing and can fix it. Sorry, don't mean to sound insulting I just want it fixed right.

The HD may be damaged and in need of replacement. Please take the computer to your local Apple Authorized Service Provider to be diagnosed and repaired.

Did you unfuse the Fusion drive?
