5.1 Testing Avira UnErase
It may happen that Avira UnErase does not display data deleted a few seconds
previously.
The causes may vary and are all related to the Windows cache. When you copy and then
directly delete files or empty the Recycle Bin then start Avira UnErase immediately to
test it, these files are not listed in Avira UnErase because they have not been properly
written on the hard disk. Windows file systems need a few minutes at most to write files
on the hard disk.
In order to be sure that files have actually been written on the hard disk, when testing
UnErase you should either restart the computer before deleting the files or run
CHKDSK. Only then can you be sure that the files have been saved on the hard disk and
that Avira UnErase can find them.
5.2 Golden rules
We have prepared this list of tips to make your file recovery even easier. Zudem erhalten
zum besseren Verständnis eine Erklärung, wie das Löschen and of the recovery
procedure is included.
The deleting process differs from one file system to another. Basically however, there is a
"list of contents", which refers to various sectors and clusters on the hard disk. When
deleting a file, you do not actually delete the sectors of the hard disk, but the entry in
this "list of contents" and thus you mark the sectors allocated to that file as available for
the following write operations. You can restore a file as long as these sectors were not
actually overwritten, meaning that the content of the sectors can be restored.

Please perform regular backups of important files!

Be careful when deleting files.
f
If possible, stop all write operations on the drives from which you want to recover
the files. Every write operation could overwrite relevant sectors from which you need
to recover data. If you want to restore files from the system drive, we recommend
unplugging the computer from its power source (not just shutting it down) and then
using Avira CIA Commander as an immediate aid for system and data access!
