Corrupt data could be in a number of tables ...

There are two kinds of corrupt data ... damaged data that the Repair in phpMyAdmin might by able to fix ... and the corrupt data where you have bad records of data in the database tables and these need to be checked through to try to locate the bad records ...

Checking for bad records can be hard as there are a lot of checks to be done on the database table records ...

If you have a good copy of your database, then that can just be reloaded ...

If you do not, and do not want to manually re-add all of your data, then it might be worthwhile having someone go through your database table records and see if they can spot the problems and clean them up ...

You might need someone to do this kind of clean up for you and you might post in the Commercial Help Wanted to see if anyone is available to help you ...
