open-in-new
<h2 id="overview">Overview</h2> <p>The program was first introduced in MS-DOS 6.2<a class="footnote-ref" id="fnref:1" href="#fn:1"><sup>1</sup></a> and succeeded its simpler predecessor, <a href="/facts/CHKDSK/ac8yljw2">CHKDSK</a>. It included a more user-friendly interface than CHKDSK, more configuration options,<a class="footnote-ref" id="fnref:2" href="#fn:2"><sup>2</sup></a><a class="footnote-ref" id="fnref:3" href="#fn:3"><sup>3</sup></a> 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 <a href="/facts/Recover_(command)/YJVQqdNC">recover</a> utility.<a class="footnote-ref" id="fnref:4" href="#fn:4"><sup>4</sup></a> Unlike CHKDSK, ScanDisk would also repair crosslinked files.<a class="footnote-ref" id="fnref:5" href="#fn:5"><sup>5</sup></a> </p><p>In <a href="/facts/Windows_95/1E1L93qC">Windows 95</a> onwards, ScanDisk also had a <a href="/facts/Graphical_user_interface/wBlQFWDP">graphical user interface</a>, although the <a href="/facts/Text-based_user_interface/bngNtqIY">text-based user interface</a> continued to be available for use in single-tasking ("DOS") mode.<a class="footnote-ref" id="fnref:6" href="#fn:6"><sup>6</sup></a><a class="footnote-ref" id="fnref:7" href="#fn:7"><sup>7</sup></a> </p><p>However, ScanDisk cannot check <a href="/facts/NTFS/dryNM3BK">NTFS</a> disk drives, and therefore it is unavailable for computers that may be running <a href="/facts/Windows_NT/EtccWvxQ">NT based</a> (including <a href="/facts/Windows_2000/amJIt9gz">Windows 2000</a>, <a href="/facts/Windows_XP/IozrkAYS">Windows XP</a>, etc.) versions of Windows; for the purpose, a newer CHKDSK is provided instead. </p><p>On <a href="/facts/Unix-like/YAKrAxzd">Unix-like</a> systems, there are tools like fsck_msdosfs<a class="footnote-ref" id="fnref:8" href="#fn:8"><sup>8</sup></a> and dosfsck to do the same task. </p> <h2 id="see-also">See also</h2> <ul><li><a href="/facts/Fsck/v9IpnBLS">fsck</a></li> <li><a href="/facts/List_of_DOS_commands/d72UqhJ3">List of DOS commands</a></li></ul> <h2 id="further-reading">Further reading</h2> <ul><li>Cooper, Jim (2001). <i>Special Edition Using MS-DOS 6.22, Third Edition</i>. <a href="/facts/Que_Publishing/UNq9rds8">Que Publishing</a>. <a href="/facts/ISBN_(identifier)/15AdSPa9">ISBN</a> 978-0789725738.</li> <li>Stinson, Craig (1998).
