Tool to carve fragmented files

August 27th, 2017, 5:56

I'm currently working on a tool which is supposed to carve fragmented files, like, extracting fragmented JPEGs from a volume without referring to any kind of filesystem metadata. However, the process is very computationally expensive, and any practical speeds require pretty high-end hardware. If I ever was to sell the resulting tool, which would you prefer, - a standalone software with some ungodly hardware requirements, or a website where you can upload your disk image and get the recovered files back after a while, for a reasonable per-GB price?

Likely option A. Customers are overly paranoid about data security.

First option too.
Not easy to upload the entire image of a HDD.

Well, I have it now; not sure if I'm allowed to post a link, but if someone wants a license key to play with, PM me.

The download is now available at http://www.klennet.com/carver/

It currently works with JPEGs only. I made some provisions for CR2 and NEFs, but that part is still not ready.

Hi,
Only 64 Bit No 32 Bit :(

Given 8 GB RAM minimum requirement, yes, no 32-bit.

Well,
i have a case of fragmented jpg files .Lady clicked photos on a sony camera and formatted on a android phone .She was using a microsd in a adapter initially in camera .I will Try out in 64 bit .

Brother Haque ,
I am using Windows 7 Pro 32 Bit on most PC.Anyways I tried this 820kb tool on a very very powerful laptop the cpu was ok for this but the tool is a memory resource hog .My 8 gb physical memory was out after 2nd pass and in the third pass when its trying to to combine fragmented jpg it started creating virtual memory in windows and it passed 35gb then it crashed ,I think resource management should be done in the tool ,no idea how to test on live case now

Amarbir[CDR-Labs],

How big is the media you were recovering for it to consume 35GB RAM?

Well,
I am not sure as i am in home once i saw your post but i think its 32 gb,You like remote access to check it

How's this project going? I see on the website it now lists CR2 and NEF files. Any progress toward making it optimized and more useful for larger memory stores such as HDDs?

I know a wedding photographer who'd pay anything right now for a working program that could get back a shoot which was lost on a badly fragmented 4Tb drive.

Come January, probably I will optimize it enough to at least do a reasonable attempt against a hard drive. Currently, it will take impractically long time with any hardware imaginable.
