TuneUp Disk Doctor
Introduction
When working with your computer, many files are constantly being read and
written – regardless of whether you are editing a text document, looking at
pictures or simply starting an application. Modern operating systems place all
files in special file systems to allow quick access to all necessary information at
any time.
File systems keep track of every file and folder on a drive and save information
about these objects such as their name, size, date of last access, location and
much more.
The file systems used by Windows for hard drives, USB sticks, memory cards
(such as those used by digital cameras) and diskettes are called FAT and NTFS.
The newer of the two file systems, NTFS, allows you to save additional
information such as access authorizations and is better suited for the size of
modern disks than FAT.
Over time, errors may occur in these complicated systems - due to defects in the
drives being used, power outages or software crashes. If these errors are not
found and corrected quickly, this can lead to error messages, application
problems and, in the worst case, total loss of important files.
TuneUp Disk Doctor performs a thorough analysis of your disk drives and their
file systems. If errors are found during analysis, they can be automatically
repaired to prevent data loss.
Using TuneUp Disk Doctor
After starting TuneUp Disk Doctor, a wizard will appear to guide you through
the analysis and repair of your drives step-by-step. In the first step, select the
drives that you would like to analyze. To do this, you simply need to check the
box in front of the drives you wish to analyze. Then, click Next.
In the next step, you can select whether you would like to perform a normal
analysis or a thorough analysis. As the thorough analysis can take quite some
time for larger drives, a normal analysis of the selected drives is usually
sufficient. This usually only takes 1-2 minutes. However, if errors occur on your
system or Windows reports problems with reading or writing data, a thorough
analysis is recommended. Make your selection and click Next to start the
analysis.
