SSD not showing in disk management

Hello all,

This is my first post here, thanks for having me.

I have a bought an ASUS N550JK and now I want to add a 240GB SSD to it (Intel SSDSC2BW240A401). I removed my optical disk and have a HDD Caddy to add my SSD.

After this I didn't see the SSD in my computer, so I started searching and found several things. But it didn't answer my problem.

In the device management the Intel SSD is shown, but in the disk management I cannot find it:

I also checked my BIOS and the SSD is shown there. Can someone say what I doing wrong?

Thanks in advanced.

Kind regards,

Menno Veen

PS: Intel Toolbox can also not find the SSD...
