17.3.2 Errors and their repairing in simple mode
██ In general there are three types of errors that can occur:
 Inconsistency in file allocation tables (FAT): FAT table contains information about
every file and directory stored in the image including the size and the exact position,
where it is stored. In each image there are two FAT tables copies that have to be
consistent. If just one FAT table is corrupted, you can save your data using the other
table. If the FAT tables aren't consistent, CheckImage chooses for you the table with less
errors. When you choose to repair the image, the FAT table inconsistency is repaired also.
 Lost clusters: Some sectors (the whole image is divided into sectors, each sector contains
512 bytes of data) in FAT table are marked as if they were filled with data, but they don't
belong to any file in the image. These sectors are marked as free space by repairing of the
image.
 Damaged object(s): A damaged object means either a file or a directory that contains
errors. The repair method which will be used depends on the error(s) found in each
damaged object. Some of them even can't be repaired and have to be deleted.
Information about errors in the image you have checked is in the line at the bottom of the application
window.
