DOCUMENT:Q219878 10-AUG-2001 [winnt] TITLE :"Warning! Your Drive May Be Corrupt" Starting Windows NT 4.0 SP4 PRODUCT :Microsoft Windows NT PROD/VER:winnt:4.0 SP4 OPER/SYS: KEYWORDS:kberrmsg ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft Windows NT Server version 4.0 SP4 - Microsoft Windows NT Workstation version 4.0 SP4 - Microsoft Windows NT Server, Enterprise Edition version 4.0 SP4 ------------------------------------------------------------------------------- SYMPTOMS ======== If you have Windows NT 4.0 Service Pack 4 (SP4) installed, you may see the following message when Chkdsk runs during a restart of Windows NT: WARNING! Your drive may be corrupt. Please let AUTOCHK run. Skipping AUTOCHK on a volume may lead to an unmountable volume. Skipping AUTOCHK on a system drive may lead to an unusable system. AUTOCHK resumed. The following message may also appear in your event viewer's Application log: Event ID: 1001 Source: Autochk Description: WARNING! Your drive may be corrupt. Please let AUTOCHK run. Skipping AUTOCHK on a volume may lead to an unmountable volume. Skipping AUTOCHK on a system drive may lead to an unusable system. AUTOCHK resumed. CAUSE ===== This message has been added to Chkdsk starting with SP4. It does not necessarily indicate that there is any problem on the hard disk. It is a warning that skipping Autochk (the automatic running of Chkdsk after an improper shutdown) might lead to problems on your hard disk. When a Windows NT-based computer is shut down improperly (for example, by a power failure), Autochk scans the hard disk the next time you start Windows NT. This message is displayed and is recorded in the Application log every time Chkdsk is run during startup, whether it was invoked by Autochk or manually by the user. MORE INFORMATION ================ For more information about the Autochk feature, see the following article in the Microsoft Knowledge Base: Q187941 An Explanation of CHKDSK and the New /C and /I Switches Additional query words: checkdisk corruption ====================================================================== Keywords : kberrmsg Technology : kbWinNTsearch kbWinNTWsearch kbWinNTW400search kbWinNT400search kbWinNTW400sp4 kbWinNTSsearch kbWinNTSEntSearch kbWinNTSEnt400sp4 kbWinNTS400sp4 kbWinNTS400search Version : winnt:4.0 SP4 Issue type : kbprb ============================================================================= THE INFORMATION PROVIDED IN THE MICROSOFT KNOWLEDGE BASE IS PROVIDED "AS IS" WITHOUT WARRANTY OF ANY KIND.
