File retrieval from an overwritten drive involves scanning the storage for file structures, metadata, or data fragments that remain after new information has been written. The process becomes harder as more of the original file is replaced. If you notice that important data has been overwritten, stop using the drive and do not install programs or copy files onto it. Recovery software such as Notchox can scan supported storage devices for remaining recoverable files. Some files may be partially damaged even when found, so previewing recovered data before saving it is useful when the software supports that feature.
