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:
q Part of a file is missing
q A file includes parts of other files
q 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.
