The system automatically notices that the disk has changed and updates the mount point contents to reflect the new medium. Provided synchronization has occurred, a different disk can be inserted into the drive. Under normal circumstances, the disk should have been synchronized and then unmounted before its removal. For example, a floppy disk that has been supermounted can be physically removed from the system. Some Unix-like systems have also introduced a concept called supermounting, as implemented in the Linux supermount-ng project. Utilities have therefore been developed to detect the presence and availability of a medium and then mount that medium without any user intervention. Common examples include USB mass storage (flash drives), memory cards, CD-ROMs, and DVDs. They allow programs and data to be transferred between machines without a physical connection. Removable media have become very common with microcomputer platforms. There are some utilities for Unix-like systems that allow the mounting of predefined file systems upon demand. In some situations, there is no need to mount certain file systems at boot time, although their use may be desired thereafter. System administrators define these file systems in the configuration file fstab (vfstab in Solaris), which also indicates options and mount points. All Unix-like systems therefore provide a facility for mounting file systems at boot time. In many situations, file systems other than the root need to be available as soon as the operating system has booted. Some of these strategies have been coined "auto-mounting" as a reflection of their purpose. Unix-like operating systems often include software and tools that assist in the mounting process and provide it new functionality. When the medium (or media, when the filesystem is a volume filesystem as in RAID arrays) is mounted, these metadata are read by the operating system so that it can use the storage. Each different filesystem provides the host operating system with metadata so that it knows how to read and write data. Before any of them can be used for storage, the means by which information is read and written must be organized and knowledge of this must be available to the operating system. As of 2013, magnetic media are still the most common and are available as hard disk drives and, less frequently, floppy disks. Many different types of storage exist, including magnetic, magneto-optical, optical, and semiconductor (solid-state) drives. Normally, when the computer is shutting down, every mounted storage will undergo an unmounting process to ensure that all queued data got written, and to preserve integrity of file system structure on the media.Ī mount point is a location in the partition used as a root filesystem. The user can access files and directories on the medium from there.Īn opposite process of mounting is called unmounting, in which the operating system cuts off all user access to files and directories on the mount point, writes the remaining queue of user data to the storage device, refreshes file system metadata, then relinquishes access to the device, making the storage device safe for removal. The location in VFS that the newly mounted medium was registered is called mount point when the mounting process is completed, In general, the process of mounting comprises the operating system acquiring access to the storage medium recognizing, reading, and processing file system structure and metadata on it before registering them to the virtual file system (VFS) component. Mounting is a process by which the operating system makes files and directories on a storage device (such as hard drive, CD-ROM, or network share) available for users to access via the computer's file system.
