At this point your best bet is to use a tool like photorec on the<br>
partition to see what data it can salvage, though on 36 TB sorting the<br>
results may be overwhelming... You'll need some other large filesystem<br>
to store the salvaged data, though.</blockquote><div><br></div><div>Photorec doesn't recreate any filesystem metadata (filenames, directory structure, timestamps, etc).</div><div><br></div><div>Hopefully you have a recent backup you can use instead of trying to go through Photorec's results.</div><div><br></div><div>Greg </div></div></div></div>
