10.If you see no error messages but there is something wrong with the data in a file, MS-DOS or an application program may have updated the storage information on the diskette incorrectly. This is probably the case if you have one of these problems:

0 Part of a file is missing

Cl A file includes parts of other files

0 An expected output file is missing.

To make the necessary repairs, use the MS-DOS program CHKDSK. See your MS-DOS Reference Manual for instructions.
