Hi Apple and Mac friends.
In System Information > SATA Device Tree
It says Apple SSD Controller is "Unknown". It also says:
"No" to both Native Command Queuing and Detachable Drive.
Is it detecting that there is an SSD there? Any ideas how it become known, instead of uknown?
Thank you.

Best to keep one issue on one thread.
What shows if you select System Information's "Storage" instead of "SATA?" My iMac has the factory 1TB SSD options and shows only the Inter shipset for "SATA" but properly shows the SSD if I select Storage:
Hi. I tried everything close to 11 days now (starting at 4 to 5am until 10 to11pm, it's quite stressful troubleshooting but that's how one is stretched to become more advanced), I think somehow the Fusion Drive split (it's just a separate SSD and a mechanical hardisk, fused by software thankfully. Thankfully it's not hybrid type whereby the SSD is hardware, in the hardisk itself) but if I boot to Boot Camp, Windows 10 can see a Disk 1 drive. I think if I initialized it there, macOS will see the Apple Blade SSD again and it can be fused again with the diskutil resetFusion command in Terminal as per Apple website instructions.
Pray, fast and hope, this theory is correct.
