Recovering deleted files

I need a working program to recover a PDF and Word file which I deleted from downloads and recovery bin.
A text file should be easier to recover than anything else, right? right, Sup Forums?

Discussion and help please.

no, text files are hard because they're headerless/magicless, there's no easy way to tell where the beginning and end of a text file is, or if it's a separate file and not just part of something else
good thing pdf's and word documents aren't text files

What about image and video files on an Android phone after a system reset?

flash is almost impossible to recover from as the controller is the only device that knows where the data is stored. You need to manually recover it from the flash of get controller specific recovery tools.

Hard drives are still okay, they just delete the link to the files. you can scan the area and recover as long as the sector hasn't been over written

for flash it depends on whether it was "trimmed" or not
filesystems still unlink the same as they do on a hdd, it can just also trigger a trim, which actually erases the block(s) the data was on

The files are spread across the flash, only the controller knows where they are. you need to get specific recovery tools that can speak with the controller directly, afaik they are not available to end users.

a filesystem unlink without trim doesn't change where the actual data is, the controller will give you the data if you ask for it

forensic analysis of flash is for advanced things relating to the CoW-like internal operation of flash-based drives, specifically that 'overwriting' a file at the logical layer doesn't necessarly mean the same data will be internally overwritten at that time

tldr; you're describing a different thing

-- to be clear
regular tools will work on flash media if the data in question has neither been logically overwritten, or trimmed

I'm not saying the data is not there, I agree that the flash wont overwrite until absolutely necessary as it's got it's own wear algorithms.

>the controller will give you the data if you ask for it
this is wrong, if you delete the link to where the data is on all those cells from the controller, that's it.. you can never recover that without being able to dumping the whole flash cell using specific tools. ie you need to speak with the controller directly using specialised tools.

That's why secure erasing SSD's is pretty fucking hard, there's parts of flash both in reserve and bad blocks that is not visible or addressable to the OS, it's all managed by the onboard controller.

HDD's are different in that the OS knows where every sector is physically located on the disk and it can pull from everywhere and most of the files are written sequentially

>if you delete the link to where the data is on all those cells from the controller
you can't do that yourself, you can only overwrite (logically) or trim (what that does exactly is up to the controller)
i'm talking about filesystem unlinking, aka, regular old "delet this", which DOES NOT OVERWRITE THE DATA on its own, and without trim to tell the ssd that the data is now "free", the ssd has NO WAY of knowing there's nothing of importance there, and so if you request data from the logical addresses the data was in, you will get the data back, until such time as it is trimmed or logically overwritten

It's extremely good in my opinion.

Root phone and try "diskdigger pro", worked wonders for me on my old rooted Galaxy Note. Got most of my deleted images back. It is a paid app and does not work without root but it did do its job.

you could also just netcat your mtd contents over and run photorec
advantages being that they're foss, and you probably already have netcat on the phone, so you don't need to install anything (especially important not to write anything to something you want to recover deteted things from)

I cant acess the phone. It's stuck in a bootloop.

do you have TWRP installed, or can you install it?
you can do a raw image backup using that as well, without touching your system or data partitions

I have a similar problem. Some files in one of my folders on my phone simply vanished, few are left with jumbled filenames, and some are intact. Those are all musical files, so the should be easier to find again, right?

Anything you guys can recommend for mac formatted HDDs?

photorec ignores filesystems and only looks for headers

what the header of these images was.... damaged? and the tools used thus far kind of gets as far as recognizing that it's an image and tries to pull together the jpeg file but it's missing 2/3 of the file?
