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.

Given 8 GB RAM minimum requirement, yes, no 32-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?
