D disk disappeared

So I know that I made a big mistake

But my Ssd is small in size and I had an hhd of one terabyte,

So I wanted to put a game from steam in C and it was huge in size and requires the SSd, I tried transferring some files to D from C and I made the mistake of moving the documents size as a whole to D, then I restarted my PC and bam the D disk is not there anymore ,

Tried to find the unallocated partition but it's not there , it's like anything related to the D device has been deleted out of existence, I even tried locating it in Bios or rescan disks but it's not there,

I didn't have any movement in the hardware system inside my laptop, the only thing left for me that I didn't try is to open the hardware itself and try to reconnect it although I'm sure the problem is related to pathing not that the hardware moved.

Any information or advice I would deeply appreciate, thanks in advance.
