MySQL Back Up from  ibdata file

I had some of my tables stored in MyISAM storage engine.

When I restored the DB it had dropped records from the MyISAM table.

I have a file on my hard drive named "ibdata" which is the exact same size as the database before it was restored.

Is there anyway I can restore the lost records from here?

Praying very hard for a positive response.

While tagit's directions from the other post will generally work, you'll need other data files for MyISAM.  The ibdata file is used for the InnoDB transaction-based engine.  If your data loss came from an InnoDB table, you would certainly need that file.

For MyISAM tables, there are three files of interest for each table.  The .FRM file contains the definition, the .MDY file contains data, and the .MYI file contains the index information.  These files are held in the data subdirectory, filed under the database's name (usually /var/lib/mysql/data/database_name).

Otherwise, the same instructions apply - stop MySQL, make it use the old tables (either re-point the directory, or move the files around), start MySQL, dump what you need, revert to the current tables.

Thanks for the points but is this really a solution? If so then routinet's comment deserves acknowledgement as this wasn't obvious in the other post.
