  <div class="attr SUMMARY">
You're experiencing Volume BTREE Structure Corruption. When this happens, the hard drive needs to be reformatted. It is possible for software to bomb or crash hard enough to cause format structure damage to the hard<BR>
drive. This is one of the main reasons we strongly suggest frequent backups.<BR></div>
