Weird SSD disappearing issues

[jmbswii]

My laptop, the Lenovo ideapad y700, came with two pieces of storage space: a 100 GB and a 900 GB harddrive. The 900 GB hard drive, recently, has completely disappeared off my computer. It doesn't show up in any folders, and it doesn't show up in Disk Management. However, I will sometimes get a notification that a hard drive is "detected", then removed from the Intel Storage Technology app. I got a screenshot of the info before it went away, as well as what it looks like normally:

What's going on? And how can I get my storage back?

Could be a loose cable(s).

If that was the case, how would I go about fixing it?
