Windows uses MountMgr to manage drive letters. MountMgr will assign the next available drive letter to each device added, regardless of type. With the system drive assigned the letter C:, there may be other IDE, SATA or USB devices, such as a DVDROM or a Flash drive assigned to letters D: and E:. When adding another drive, Windows XP/2000/Vista/7/8 will assign the next drive letter available, which in this case would be drive letter F:.

Drive letters can usually be manually changed using Disk Management, however there may be some exceptions. For full details please see the relevant Instructions or Microsoft Knowledge Base article below:
