I doubt it. Not without forensic equipment. It isn't stored like magnetic media is. Try a un-delete pgm and see if there's anything left.
There's no such thing as "forensic equipment". Forensic refers to the process or purpose of data recovery for use in litigation.
There are data recovery hardware tools and software and there is forensic software used for the imaging/preparation of data for use in litigation.
in this case, either the data has been overwritten and cannot be recovered or it is at least partially still present and can be recovered with only software methods.
