I have used hard drive after data loss can I recover lost data from it?

Yodot Hard Drive Recovery software does not guarantee you to recover all files in this case. When you use your hard drive after data loss, the deleted space will be overwritten with new files and you will lose data forever. However, you can still use demo version of the software to check whether you can recover deleted or lost files which were not overwritten. If files are displaying in demo version, then you can save them after activating full version.
