It presents a sub-tree view with disk-use percentage alongside a usage-sorted list of file extensions that is interactively integrated with a colorful graphical display (a treemap ). [ 1][ 2][ 3] Created as an open-source project released under ...
Software that shows the health of the drive and its smart attributes. [ 1] Self-Monitoring, Analysis, and Reporting Technology ( S.M.A.R.T., often written as SMART) is a monitoring system included in computer hard disk drives (HDDs) and solid-state drives (SSDs). [ 2] Its primary function is to detect and report various indicators of drive ...
Microsoft Reserved Partition. A Microsoft Reserved Partition ( MSR) is a partition of a data storage device, which is created to reserve a portion of disk space for possible subsequent use by a Windows operating system installed on a separate partition. No meaningful data is stored within the MSR; though from the MSR, chunks may be taken for ...
The file system uses an index table stored on the device to identify chains of data storage areas associated with a file, the File Allocation Table ( FAT ). The FAT is statically allocated at the time of formatting. The table is a linked list of entries for each cluster, a contiguous area of disk storage. Each entry contains either the number ...
Hard links were originally included to support the POSIX subsystem in Windows NT. [59] Although hard links use the same MFT record which records file metadata such as file size, modification date, and attributes, NTFS also caches this data in the directory entry as a performance enhancement. This means that when listing the contents of a ...
The disk drive created a new level in the computer data hierarchy, then termed Random Access Storage but today known as secondary storage, less expensive and slower than main memory (then typically drums and later core memory) but faster and more expensive than tape drives. [3] The commercial usage of hard disk drives (HDD) began in 1957, with ...
Disk storage (also sometimes called drive storage) is a data storage mechanism based on a rotating disk. The recording employs various electronic, magnetic, optical, or mechanical changes to the disk's surface layer. A disk drive is a device implementing such a storage mechanism. Notable types are hard disk drives (HDD), containing one or more ...
Disk formatting is the process of preparing a data storage device such as a hard disk drive, solid-state drive, floppy disk, memory card 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 ...
