SystemRescue (Previously known as "SystemRescueCD") [4] is a Linux distribution for x86-64 and IA-32 computers. [5] The primary purpose of SystemRescue is to repair unbootable or otherwise damaged computer systems after a system crash. SystemRescue is not intended to be used as a permanent operating system.
CHKDSK requires exclusive write access to the volume to perform repairs. [14] [15] Due to the requirement of the monopolized access to the drive, the CHKDSK cannot check the system disk in the normal system mode. Instead, the system sets a dirty bit to the disk volume and then reboots the computer.
TestDisk is a free and open-source data recovery utility that helps users recover lost partitions or repair corrupted filesystems. [1] TestDisk can collect detailed information about a corrupted drive, which can then be sent to a technician for further analysis.
The system utility fsck (file system check) is a tool for checking the consistency of a file system in Unix and Unix-like operating systems, such as Linux, macOS, and FreeBSD. [1] The equivalent programs on MS-DOS and Microsoft Windows are CHKDSK, SFC, and SCANDISK.

GParted (acronym of GNOME Partition Editor) is a GTK front-end to GNU Parted and an official GNOME partition-editing application (alongside Disks).GParted is used for creating, deleting, [3] resizing, [4] moving, checking, and copying disk partitions and their file systems.
Hard disk reader. A bad sector in computing is a disk sector on a disk storage unit that is unreadable. Upon taking damage, all information stored on that sector is lost. When a bad sector is found and marked, the operating system like Windows or Linux will skip it in the future.
However, ScanDisk cannot check NTFS disk drives, and therefore it is unavailable for computers that may be running NT based (including Windows 2000, Windows XP, etc.) versions of Windows; for the purpose, a newer CHKDSK is provided instead. On Unix-like systems, there are tools like fsck_msdosfs [8] and dosfsck to do the same task.
