Data loss is an error condition in information systems in which information is destroyed by failures or neglect in storage, transmission, or processing. Information systems implement backup and disaster recovery equipment and processes to prevent data loss or restore lost data.
Data loss is distinguished from data unavailability, which may arise from a network outage. Although the two have substantially similar consequences for users, data unavailability is temporary, while data loss may be permanent. Data loss is also distinct from data breach, incident where data falls into the wrong hands, although the term data loss has been used in those incidents.
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.
Windows 7 data recovery technology is not as complex as you though. Files, usually are divided into pieces, like 4KB a piece, which means, for example, if there is a 1MB file that in your hard drive, it will be about 256 pieces of data that store every possible place in hard disk. And there is a record for hard disk, which is named as partition table, the record writes down the locations of all sectors. This helps Windows 7 to identify the file and run it when you want to.
