This article was previously published under Q71586 SUMMARY
To maintain a fixed disk, you may wish to run CHKDSK /F as a child
process from an application that runs continuously. However, you
should not do this.
CHKDSK assumes that the file allocation table (FAT) is in a stable
state. If CHKDSK detects an error and attempts to correct it by making
changes to the FAT, CHKDSK could destroy the FAT operations that
MS-DOS has done up to that point.
More specifically, if CHKDSK is run when a file is open, the chain of
clusters "owned" by the file could be altered in the FAT by CHKDSK.
When the file is closed and MS-DOS finishes updating the FAT and the
directory, you may be left with an error in the FAT.
