Please check for that.
Check disk management to see if the drive is showing there or not. Click the Start Orb and type diskmgmt and hit enter.
If it's not there, start with the easy stuff first, like opening the case and unplugging and plugging back in the cables to the drive. If a cable is failing, the drive will disappear and re-appear somewhat randomly after reboots.
