The following factors need to be fulfilled in order for data recovery from hard disk after overwriting to become possible. If the data has been overwritten in such a way that the entire sector containing the file has been overwritten, it will not be possible to recover the data. On the other hand, in cases where only a part of the sector containing the data is overwritten, it would still be possible to recover the data. Notchox will perform a complete scan to find out recoverable files and recover them wherever possible.
