<p>Some questions and hints for problems with <strong>GParted</strong>.</p>
<ol>
<li>Have you defragmented your partition (not with the Windows tool)?</li>
<li>Is it a NTFS partition (I assume)?</li>
<li>Did you have a backup as said in the <a href="http://gparted.sourceforge.net/docs/help-manual/C/gparted.html#gparted-introduction" rel="nofollow">manual of GParted</a>?</li>
<li>Have you decreased the size to a smaller value than the used space on the partition?</li>
</ol>
<p>Some explanation to my points:</p>
<ol>
<li>The reduction works only without data loss if you defragment your partition. Otherwise, GParted will remove data blocks being allocated to real files. You don't want to do this, right?</li>
<li>If it isn't a NTFS partition, it's not that easy to resize it. I don't have experiences with resizing FAT/VFAT.</li>
<li>Nuff said.</li>
<li>If you decrease the size to a smaller value than the used space, GParted will "cut" the partition with data loss.</li>
</ol>
<p>I hope, these hints will help you to solve your problem.</p>
