Deep Scan?
I'm using PhotoRec 7.0 and read the "How it Works" section but I'd like to know if this utility can actually deep-scan for overwritten data - find older data underneath newer data in other words. I couldn't find that answer in the documentation or from a GUI option but I get a few hits when searching for "deep" in the forum. Could someone tell me if PhotoRec can deep-scan in this way, either by default or if there's some option?

Re: Deep Scan?
No software can recover overwritten data.

I just read about Quick Scan, Deep Scan, and Physical Scan (https://support.norton.com/sp/en/us/hom ... help_en_us). Which scans are supported by PhotoRec?

Re: Deep Scan?
Photorec includes but is not limited to "Deep Scan" and "Physical Scan".alangrant wrote: ↑12 Apr 2019, 19:28 I just read about Quick Scan, Deep Scan, and Physical Scan (https://support.norton.com/sp/en/us/hom ... help_en_us). Which scans are supported by PhotoRec?
These are just Norton marketing terms for certain parameter sets.
If you read the documentation
https://www.cgsecurity.org/testdisk.pdf
you'll see that you are able to search on disks or limit the search to a partition. Furthermore you can specify the type of space (unallocated/complete).
The pdf file above contains as well instructions what to do for a "Quick scan" - I don't go into details because I want to encourage reading the manual!
