+<h3 id="move">How can I safely move files from one disk to another?</h3>
+<p>
+In case you need to move files from one data disk of the array to another disk
+also in the array, the 100% safe way to proceed is:
+</p>
+
+<li>
+<ul>Copy the files to the new location.
+<ul>Run a 'sync' command.
+<ul>Delete the files from the original location.
+<ul>Run again a 'sync' command.
+</li>
+
+<p>
+This process gives the guarantee that even if disks die during the sync process,
+you will be able to recover everything. It also verifies the hashes of all the
+moved files are matching the original ones.
+</p>

 <h3 id="defrag">Can I defragment the data and parity disks?</h3>
 <p>
 Yes, you can defragment data and parity disks. Defragmentation doesn't invalidate the SnapRAID data.
