D drive messing after ram examination

[terminator00000]

hi all

i opened up my computer just to check my ram modules, i took them out and then put them back in, that was all, when i started my computer again my d drive was missing with all of its files, does anyone know what the problem could be and how to fix it.

i checked all the ram modules and they're all tightly put back in but the problem still persists

Probably a simple cable coming loose. Double/triple check all it's connections. If that isn't it try it in a different sata port. When your computer is running go to start - right click my computer - left click manage - storage - disc management local and see if it's showing up there also.
