<li><font face="Verdana, Arial, Helvetica, sans-serif" size="-1"><b>Do not store
important files in the root directory.<br>
</b></font><font face="Verdana, Arial, Helvetica, sans-serif" size="-1">Files,
which are stored in the root directory, are sensitive to a loss by quick formatting,
because file entries are set-aside in the root.<br>
Avoid to store to store files directly in the root since the file disappears,
if the directory entry is damaged</font><font face="Verdana, Arial, Helvetica, sans-serif" size="-1">.
In an emergency, one can recover data very quickly if it is in a sub-directory.<br>

<li><font face="Verdana, Arial, Helvetica, sans-serif" size="-1"> <b>Defragment
the hard drive regularly</b><br>
Data is stored in successive clusters, if sufficient connected free storage
location is available. Repeated deletion and write operations fragment the
drive.<br>
<br>
<font color="#006666">An example:</font><br>
<br>
(1) (2) (3) (4) (5) (6) (7) (8) - should represent 8 small files<br>
<br>
</font><font face="Verdana, Arial, Helvetica, sans-serif" size="-1"> (1) <font color="#FF3333">(2)</font>
(3)<font color="#FF3333"> (4)</font> (5) (6)<font color="#FF3333"> (7) (8)</font>
- now files (2), (4), (7) and (8) were deleted<br>
<br>
(1)<font color="#6666FF"> (9)</font> (3)<font color="#0000FF"> <font color="#6666FF">(9)</font></font>
(5) (6)<font color="#0000FF"> <font color="#6666FF">(9)</font></font> <font color="#6666FF">(9)</font>
- disk is fragmented if a larger file is stored<br>
</font><font face="Verdana, Arial, Helvetica, sans-serif" size="-1"><br>
<br>
If data is deleted from the disk, new data can take the free place. If the
new data is larger than the old one however, the data is net set aside in
coherent range, but in fragments.<br>
When reading fragmented data the head of the hard disk has to 'jump' (i.e.
the head moves to the looked track). Thus the reading and write speed is reduced.<br>
</font><font face="Verdana, Arial, Helvetica, sans-serif" size="-1">In order
to make the read and write procedure again more efficient, it is necesscary
to reorganize the fragmented disk. After defragmentation, the data is in sequential
order and then look in such a way:<br>
<br>
(1)<font color="#6666FF"> </font><font face="Verdana, Arial, Helvetica, sans-serif" size="-1">
<font color="#6666FF">(9)</font><font color="#6666FF"> (9)</font><font color="#6666FF">
(9) </font><font face="Verdana, Arial, Helvetica, sans-serif" size="-1"><font color="#6666FF">(9)</font></font>
<font color="#0000FF"> <font color="#6666FF"></font></font></font><font color="#0000FF"></font>
(3) (5)<font face="Verdana, Arial, Helvetica, sans-serif" size="-1"> (6)</font>
- after the drive is defragmented<br>
<br>
A usually fragmented disk will degree the efficiency of a data-rescue, if
e.g. the FAT is overwritten by a quick format or a virus. Then it is necessary
to analyse exactly, how a file scattered over the disk lies. If however connected
data is present, a data-rescue is very quickly possible on the basis of the
information about its position and size. <br>
<br>
<font color="#006666">Important: A non-fragmented disk will increase you rate
of recovery because the complete data is stored at the beginning of the first
cluster of a file.<br>
</font></font><br>
<font face="Verdana, Arial, Helvetica, sans-serif" size="-1"><br>
</font></li>
<li><font face="Verdana, Arial, Helvetica, sans-serif" size="-1"><b>Do not store
important data on drives with small capacity</b><br>
The probability of the recover is lower, the smaller the disk capacity is.
Important data should be saved on a free drive. The smaller the capacity is,
the higher the risk of fragmentation is.<br>
</font><br>
<br>
</li>
<li><font face="Verdana, Arial, Helvetica, sans-serif" size="-1"><b>Defragment
your floppy disk, after data is stored on it</b><br>
Disks are fragmented with very high probability. Therefore it is advisable
with important data, to distribute the files into several directories and
then defragment the floppy disk</font>.<br>
<br>
<br>
</li>
<li><font face="Verdana, Arial, Helvetica, sans-serif" size="-1"><b>Do not use
a drive, which you require to the data-rescue.</b><br>
Do not install recovery software on a drive that contains data for your data-rescue.
Otherwise data could be overwritten and success on a data rescue becomes smaller.
Avoid working with the drive and do not save any data on it. Do not use a
usal program, including the Windows(R) Explorer, in order not to overwrite
important deleted data.<br>
For the data-recovery you should use a second hard disk.<br>
