While, there are no set rules and precautions that you should follow when recovering files using the Stellar Recovery software, it is advisable to keep in mind the following points:
1. Ensure that the hard disk you wish to recover the data from has no hardware issues.
2. While recovering data, ensure that the destination volume (where you wish to save the data) is different from the source volume (from where you wish to recover the data).
3. While creating an image, ensure that you have sufficient free space available to save the image.
