Please, does exist this kind of files recovery software?
Actualy I would need: the software which will search 1TB ISO (the copy of the bad 1TB external NTFS harddrive). And will recover the files.
On the bad harddrive, there were complete backups of a few computers: all the files from those computers, including system folders, programs, documents, photos, etc.
1) Recovery software is expected to know the structure of the well knonw file types.
2) Many of the files, what were on this bad hardrive, are still present on the another hadrive. So, the recovery software is expected to use those good files for better carving files boundaries on the bad disk.
3) Recovery software is expected to learn itself:
E.g., there are some bigger amount of files of one proprietary format on the bad harddrive. So recovery software is expected to learn the structure of those files some way, for better recovery of the files. (Much more files of this same proprietary type are on the noticed second, good harddrive - so recovery software could use them for self-learning)
