For a healthy hard drive, you should run Scandisk (or Norton Disk Doctor, etc.) if you exit a Windows session by reset button, power failure, from lockup or such. Scandisk will check for disk problems in FAT, lost allocation units, cross-linked files, etc. I use a file named: W.bat to start Windows. If somehow Windows exits abnormally, the next time the computer is started it will check for problems automatically. Here is a basic W.BAT (saved to root of C: ) @ECHO OFF ECHO CLS> C:\BAD_EXIT.BAT :: On one line: ECHO CALL SCANDISK C: /AUTOFIX /NOSUMMARY >> C:\BAD_EXIT.BAT :: :: Or, on one line for Norton Disk Doctor: :: ECHO CALL NDDD.exe C: /Q>> C:\BAD_EXIT.BAT :: ECHO CLS>> C:\BAD_EXIT.BAT :: :: Start WINDOWS here: WIN DEL C:\BAD_EXIT.BAT CLS :: End of file. ******************************** Then, add to beginning of autoexec.bat: :: On one line: IF EXIST C:\BAD_EXIT.BAT CALL C:\BAD_EXIT.BAT :: On one line: IF EXIST C:\BAD_EXIT.BAT DEL C:\BAD_EXIT.BAT **** "Call" works on DOS 5 and above, I think. Hope this helps the forum.

For MS-DOS 7.x and Win9x GUI on top, try "AutoScan=1" in MSDOS.SYS.
