SSD unrecognized - disk management says "unknown" and "not initialized

I don't understand why you have data on a SSD and OS on a HDD.

In my desktop I have 3 drives for 2 systems

System 1
- 128G SSD - C: drive for windows (83G) and Linux (45G) - OS and programs - There is still plenty space
- 1T HDD - D: drive for \Users, installation files etc - It's a Data HDD (used Kari tutorial to move \Users from C: to D:)

System 2
- 1T HDD with 2 partitions:
- C: drive (83G) - for windows - OS and programs
- D: drive (~910G) for \Users, installation files etc - It's a Data HDD (used Kari tutorial to move \Users from C: to D:)

Normally Disk 3 (system 2) remains with power connector disconnected from disk an I use system 1. As OS and programs are on the SSD it's very fast and have lot of space on the HDD.

Once a week I connect the power cable to Disk 3 (system 2) and boot with it.
From it I access disks from system 1 (SSD+HDD) to do maintenance (backup, disk images etc).

The HD was the original drive that came with the PC. I copied it to the SSD and removed the HD. So the SSD is the only drive I had in the PC. When it wouldn't boot anymore, I hooked up the original HD as the boot drive and the SSD as an external drive.

I'm hoping to get the SSD in shape to use as a boot drive again (with all, or as much, of the data, applications, etc. as it had before it had this problem).

Please clarify:

1. Your system came with Windows 7 Home Premium 64 bit on a 1.5TB HDD. Yes/No

2. "I copied it to the SSD and removed the HD" Copied what?

3. You bought a new SSD and installed Windows 10 on it. Yes/No

4. So what you copied from HDD to SSD was the data on the HDD. Yes/no

5. Was Windows 10 booting on the system after it was installed? Yes/No

6. Was it the only drive in the system or your HDD was also there as a second internal drive?

7. Then suddenly one day it did not boot. Yes/no

8. Do you know/guess any event that could have made it non-bootable? Say like you tried to create a partition, or extend a partition, installed some software, downloaded or browsed some malicious sites etc.,

The first thing we do when a system becomes unbootable is to check and see whether we can access the drive with Live Linux. ( not removing it from the system and put it inside an enclosure - which may be good or faulty we don't know.You are only introducing another "unknown" device interface )

So restore it as a boot drive and run Lucid Puppy from a pendrive.

To create a Lucid Puppy pendrive : post#8 here Is there any way of saving a completely unrecognisable hard drive?

Boot from the Lucid Puppy pendrive and check whether you can access the SSD

On how to use Lucid Puppy: Go to the topic Recovering files from the non-bootable Internal Drive: in this thread Lucid Puppy way to recover files from a non-bootable computer ( no need to read what is above the highlighted topic on creating the Lucid Puppy pendrive which is outdated) )

Sorry that my imprecise use of terms made things unclear.

2. "I copied it to the SSD and removed the HD" Copied what? => I cloned the HDD to the SSD

3. You bought a new SSD and installed Windows 10 on it. => Yes - I cloned the HDD to the SSD

4. So what you copied from HDD to SSD was the data on the HDD. => I cloned the HDD to the SSD

5. Was Windows 10 booting on the system after it was installed? => Yes, it worked for many months until a few days ago

6. Was it the only drive in the system or your HDD was also there as a second internal drive? => it was the only drive in the system

7. Then suddenly one day it did not boot. => Yes

8. Do you know/guess any event that could have made it non-bootable? Say like you tried to create a partition, or extend a partition, installed some software, downloaded or browsed some malicious sites etc.,
=> I didn't do any of those things and I don't recall downloading anything or going to any unusual sites. I don't know what could have made it non-bootable.
=> I turned on the PC and now the SSD is accessible, although it still doesn't boot. I can read and write to the SSD, but I still can't boot from it. If I can fix the Win10 to make it boot, I'd be a happy man. Hopefully without having to erase the SSD - it would be nice to not have to install various programs. The Win10 on this was the free upgrade by Microsoft via downloads.
