Inaccessible 120GB SanDisk SSD

[Spuddy]

Hello all, hope you can help me with this conundrum.

I've been using a 120GB SanDisk SSD for almost eight years as a boot drive for a Windows 10 OS.

About a month ago I got a BSOD and it started to get sluggish thereafter.

Finally I got a fatal BSOD and I was unable to boot back into windows, couldn't even repair Windows with the installation key.

Had to reinstall Windows 10 on an M.2 drive.

I've since tried connecting the original SSD through a USB adaptor but I cannot seem to get a peep out of it. Not displaying in the Disk Manager.

I had a few important documents on that drive and I'm hoping against hope that I'll be able to salvage them.
Hope you guys can give me some advice on this, it'd mean a lot to me.

Thanks in advance, Mikey.

Given it's age and use more than likely the nand have degraded. Can you get enough life from it to check the smart values? If not recovery with pc3K will depend very much on which controller it is using.
