CHKDSK and UNDELETE in MS-DOS 5.0 have a bug which can corrupt data: If the file allocation table of a disk uses 256 sectors, running CHKDSK /F can cause data loss and running UNDELETE can cause unpredictable results. This normally affects disks with a capacity of approximately a multiple of 128 MB.
It included a more user-friendly interface than CHKDSK, more configuration options, [2] [3] and the ability to detect and (if possible) recover from physical errors on the disk. This replaced and improved upon the limited ability offered by the MS-DOS recover utility. [4] Unlike CHKDSK, ScanDisk would also repair crosslinked files. [5]

This behaviour of chkdsk /r /f does not occur on FAT32 or exFAT volumes. According to MS it is a feature and not a bug because it speeds up the scan a little and they assume that you don't use the system for other things anyway while running chkdsk x: /r /f, but it is known tl cause a lot of problems, so imho it should be mentioned here.
Shared-disk file systems (also called shared-storage file systems, SAN file system, Clustered file system or even cluster file systems) are primarily used in a storage area network where all nodes directly access the block storage where the file system is located. This makes it possible for nodes to fail without affecting access to the file ...
This method of file protection was basic. It determined system files by file extension and file path. It was able to restore files from the installation media or a source specified by the user. Windows 98 did not offer real-time system file protection beyond file attributes; therefore, no preventive or reactive measure was available.
SHARE: File sharing and locking support. SORT: Sorts input. SUBST: Substitutes a drive letter for a subdirectory. SYS: Transfers the system files to another drive to make it bootable. TREE: Display a directory tree. XCOPY: Extended file copy. Standard DOS device drivers: ANSI.SYS: ANSI console driver. EMM386.EXE: Expanded memory manager.
Partially recovered files where the original file name cannot be reconstructed are typically recovered to a "lost+found" directory that is stored at the root of the file system. A system administrator can also run fsck manually if they believe there is a problem with the file system. The file system is normally checked while unmounted, mounted ...
