| Aug 22, 2020 at 12:04 | comment | added | Redrighthand | OK thank you, I will edit. No, I was not able to get Yosemite on internal SSD. The first OS X install was done from internet recovery onto one of my external SSDs and it was Yosemite. I made a boot loader for Sierra from there; also put Catalina on one SSD and Sierra on another. The internal SSD is never recognised not even in Catalina. When it is installed [ together with start-up pointed to external SSD] it boots but takes much time. Hard reset: I used as the term for holding the pwr key until it shuts off. | |

What do you mean 'hard reset'? It's not clear from your post whether you were able to install Yosemite on the internal SSD or not. If the drive is absolutely not showing in Disk Utility, or with Terminal diskutil list, then it seems likely that it has failed. Data recovery from failed SSDs is much harder than mechanicals, I believe, but still may be possible.
