Selecting tables for repairing
Use this step of the wizard to define repair options and select the tables to be repaired using MySQL routines.
Options
Quick
Perform a repair of the Index tree only.
Extended
Create the Index row by row instead of creating one index at a time with sorting.
Use .FRM
Use this mode if the *.myi file is missing or if its header is corrupted. In this mode MySQL will recreate the table using information from the *.frm file.
To select a table, you need to move it from the Available tables list to the Selected tables list. Use the 
buttons or drag-and-drop operations to move the tables from one list to another.
Click the Next button to proceed to the last step of the wizard.
