Before you begin a recovery session, you should make sure you've addressed every item on this checklist. You should have already taken care of some of these before you installed Nucleus KernelMacintosh Data RecoverySoftware:
Remember the golden rule of data recovery: never change anything on the Bad Device! (We know you're sick of hearing it at this point, but please believe us, it's for your own good).
Check that you have enough free space on the Good Device. Remember, you may need more free space than the amount that your lost data may take. If you don't have enough free space, you may need to use a different Good Device. You should review the pre-installation checklist for more details about what you should consider when checking your available memory.
Close all other applications. This will ensure that system resources won't be diverted to other programs during the recovery session.
