In order to make the most of Stellar Phoenix Windows Data Recovery, you should consider a few things when proceeding for recovery:
Do not save the recovered files to the same drive that you are scanning. This would make the deleted files overwritten before they can be recovered. You should always save your data to a different partition or drive.
Do not save the recovered data to a corrupt or failing drive. You should always verify the destination media for corruption and other related issues.
The above precautions should be followed while performing recovery. Besides this, you should immediately stop using the drive for adding or copying files to improve your chances of successful recovery.
