6.Did you receive one of the following MS-DOS error messages?

Disk Drive Error: Abort, Ignore, Retry?Disk error reading drive d:Disk error writing drive d:

If you see one of these messages, make sure the diskette is properly inserted in the drive. If the problem persists, try removing the diskette and reinserting it.

If the error message still occurs, you may have a defective diskette. Try copying the files from the bad diskette to a new diskette.

7.If you see no error messages but there is something wrong with the data in a file, the operating system 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:

Cl Part of a file is missing

Ll A file includes parts of other files D An expected output file is missing.

If you are using MS-DOS use CHKDSK to make the necessary repairs; see your MS-DOS documentation for instructions. You may also have some special diagnostic software you can use to check your diskettes.
