On Windows NT operating systems, CHKDSK can also check the disk surface for bad sectors and mark them (in MS-DOS 6.x and Windows 9x, this is a task done by Microsoft ScanDisk). The Windows Server version of CHKDSK is RAID-aware and can fully recover data in bad sectors of a disk in a RAID-1 or RAID-5 array if other disks in the set are intact. [11]
Shared-disk file systems normally do not scale over 64 or 128 nodes. Shared-disk file systems may be symmetric where metadata is distributed among the nodes or asymmetric with centralized metadata servers. CXFS (Clustered XFS) from Silicon Graphics (SGI).

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 ...
There are two file recovery mechanisms in the TestDisk package: [2] TestDisk proper uses knowledge of the filesystem structure to perform "undelete". PhotoRec is a "file carver". It does not need any knowledge of the file system, but instead looks for patterns of known file formats in the partition or disk image.

The Linux version has no graphical user interface, although extensions created to simplify usage under Linux. [48] [49] In the Linux version of Hard Disk Sentinel, it still is limited like the DOS version.
