This *Command checks that the map of an E- or F-format disc has the correct checksums and is consistent with the directory tree.
*CheckMap [disc_spec]
disc_spec | Name or number of disc drive |
If only one copy of the map is good, this command lets you rewrite the bad one with the information in the good one.
If bad map information cannot be cured, you should backup all of your files and then reformat your hard disc. Contact your supplier for more information.
