hi, so basically my computer randomly crashed and upon trying to reboot the computer it would not start. long story short i think the ssd which was containing my OS on has been corrputed or something. I redownloaded windows onto my other hardrive and got it all working again. however the original ssd does not show up in bios but it shows as 'uknown device' in device manager and shows up as 'disk 0' in disk manager but needs to be initialized. when i try initiliaze the disk it comes up with ' a device which does not exist was specified. The SSD does not show up in other places like my computer. i used diskpart and it recognises the disk but has size 0b and free 0b. i have tried changing wires and ports and that does not fix the problem. I am completely stumped on what else to try. i have some important data on the SSD that ideally i can retrieve.
