Disk formatting

Disk formatting is the process of preparing a data storage device such as a hard disk drive, solid-state drive, floppy disk or USB flash drive for initial use. In some cases, the formatting operation may also create one or more new file systems. The first part of the formatting process that performs basic medium preparation is often referred to as ""low-level formatting"". Partitioning is the common term for the second part of the process, making the data storage device visible to an operating system. The third part of the process, usually termed ""high-level formatting"" most often refers to the process of generating a new file system. In some operating systems all or parts of these three processes can be combined or repeated at different levels and the term ""format"" is understood to mean an operation in which a new disk medium is fully prepared to store files.As a general rule, formatting a disk leaves most if not all existing data on the disk medium; some or most of which might be recoverable with special tools. Special tools can remove user data by a single overwrite of all files and free space.
