Step-by-step explanation:
Since you are using Windows Server 2012 these tasks are much easier. In order to accomplish this, you simply need to click on Disk Management in the GUI and then right-click on the 200 GB drive and click on the option that says "Extend Drive". Finally, choose the max available space for the drive and click accept. This will extend the drive completely to use all of the space. The same process can be done for changing the Drive Letter and Volume Label by right-clicking the drive and choosing the corresponding option. In order to get convert the file system to NTFS (assuming it is Fat32) you simply need to open command prompt and type the following command.
convert m: /fs:ntfs
where m is the actual drive letter of the drive in question.
