Windows 10: Partition not showing up in File Explorer

Hello!I would like to ask for your help. I have an SSD Crucial CT2000MX500SSD1 that I've had installed for more than one year. It was assigned one partition disk on the PC Operation system: Win 10, x64. Yesterday everything was working fine, but when I started the PC today, it looks like the whole disk disappeared. Everything I had installed or saved to the disk is now gone. The SSD shows up in Disk Management and the system says that the space is "Unallocated".I have another SSD where the operation system is installed to, and there is no problem with that one Kingston SA400S37240G.What

W7 Hard drive partition issue

to get rid of that 100 meg windows partition that setup creates for you on a new install on a blank hdd:

- press shift+f10 when on the partition management screen in setup <-- this opens a command prompt
- diskpart <-- start the windows command line partition management tool
- list disk <--- list the installed hdds in this computer for the next step
- select disk 0 <- might have to replace 0 with the number of the correct disk
- clean <-- this will erase all data on the disk you selected one step up- dont use the wrong disk!
- create partition primary <- creates a primary partition taking up all space on the drive, adjust the command if necessary
- exit, exit to exit diskpart and the command prompt
- click refresh in partition manager and select your newly created partition and install to that
