<p><font face="Verdana, Arial, Helvetica, sans-serif" size="-1" color="#006666">Data-loss
results from the fact that the direcotry entries and/or the FAT are deleted
or contain incorrect information</font><font face="Verdana, Arial, Helvetica, sans-serif" size="-1">.
</font><font face="Verdana, Arial, Helvetica, sans-serif" size="-1">The operating
system works at an access to files as follows: Read data from directory entry
-> Read data in the data area-> Read informationen from the FAT and repeat
from next to last step until file is completely read. If the directory enties
and/or the FAT are incorrect or deleted, the operating system can not read however
any longer, although this is still in the data area. This is the reason why
users think, their data is lost - in reality it is still available. Finding
this data can be very complex however somtimes, since the entire drive has to
be examined.</font></p>
<p><font face="Verdana, Arial, Helvetica, sans-serif" size="-1" color="#006666">Data-loss
of the content itself</font><font face="Verdana, Arial, Helvetica, sans-serif" size="-1"><br>
Data is completely lost, if the content is damaged or overwritten (the file
was not lost due to incorrect information in the FAT or the directory entries).</font></p>
<p><font face="Verdana, Arial, Helvetica, sans-serif" size="-1"><b>This could
have the following causes:</b></font></p>
<ol>
<li><font face="Verdana, Arial, Helvetica, sans-serif" size="-1">The Hard disk/floppy
disk is physically damaged</font></li>
<li><font face="Verdana, Arial, Helvetica, sans-serif" size="-1">Viruses or
something else destroyed the data</font></li>
<li><font face="Verdana, Arial, Helvetica, sans-serif" size="-1">Writing other
files to the disk has led to it, that some or all clusters of a file were
changed. In this case only a part of the data can be recoverd.</font></li>
