Normal vs. Thorough analysis
Normal Analysis
Normal analysis takes approx. 1-2 minutes and is generally sufficient.
Normal analysis is carried out in several phases. The table below shows explanations of all possible steps (only
the first three lines are performed during the normal analysis).
Thorough Analysis
Thorough analysis covers all of the steps of the Normal analysis. In addition, your drives will be checked for
physical defects.
Storage space on drives is divided into so-called sectors, which are usually 512 bytes in size each. In order to
detect physical defects on a drive, the thorough analysis checks the performance of each of these sectors.
The length of this analysis depends on several factors, including the size of the drive and the degree of frag-
mentation. You should allow at least 5 to 20 minutes.
The following table explains all possible steps.

Normal and thorough analysis
Checking
files and
folders
(NTFS and
FAT)
Every element in the file system is checked. The program ensures that the structures of all files and
folders are correct.
Checking
indexes
(NTFS
only)
Indexes are references to folders in the NTFS file system. If any of these indexes are damaged, the
associated folders will not be displayed in the file system.
If any of your files or folders have suddenly "disappeared", there is a good chance that they will be
recovered after repairing the file system.
Checking
security
descriptors
(NTFS
only)
Files and folders in the NTFS file system are usually protected by security descriptors that prevent
access by unauthorized users. During the analysis, errors in these descriptions are found and cor-
rected.
Only thorough analysis
Checking
file data
(NTFS
only)
All sectors of the disk that currently contain files are checked. This will ensure that no read errors
take place when working with files, If sectors are found that require multiple read attempts to suc-
cessfully read the data, the file data contained will be moved to a sector that is free of errors. The
sector is then marked as defective. This prevents future problems.
Checking
free disk
space
(NTFS and
FAT)
All drive sectors that do not contain any files will be checked for error-free readability. If errors
occur during this analysis, the sector in question will be marked as defective to prevent files from
being saved there in the future.
