Yeah actually that's a very good idea.

And you can simply do (without globstar)

Code:

find ./ -type f -exec file {} \; | grep "Berkeley DB"

(And replace ./ with the directory path)

I'm getting this error back:

find: missing argument to '-exec' I guess something's missing from the line?

You probably need to escape the braces, like this:

Code:

find ./ -type f -exec file \{\} \; | grep "Berkeley DB"

Another option, if you have Linux/Cygwin/(probably)OSX, you can search through all of the extensionless files recovered by Photorec and use the `file` command to determine the type. Wallet files appear as "Berkeley DB (Btree, version 9, little-endian)", and so you should be able to find it relatively easily by running something like `file ** | grep "Berkeley DB"` (if you have globstar enabled, though there are many other ways of recursively searching every file within a specified location). You can use this technique for other file types as well, though anything plaintext will simply show up as "ASCII text" so it'll only help for binary file types with a specific identifier such as PNG (though presumably Photorec handles much of this, given the name).

If you copy pasted it properly shouldn't have any problems..

Try Recuva recovery software and search for wallet.dat or just type .dat you can search it in specific participation, you can also search for any other format you need for.

I think I tried that - I think it's only for Windows. But even so, the majority of the files I recovered extension was renamed to .txt.

Nice detective work

But those are from my online wallet... This is a new system I built a couple of months ago to start to start hosting pools so I had to download the client.

Try checking history of your browser. Somehow if you checked your balance of an address in blockchain or any other exploerer, you might get it from browser.

Wouldn't you only need the private address? no need for the public one if you have the private one, correct? I hope you are able to find your cons, I know it sucks to lose coins from technical issues.

I have to find the wallet.dat files first! Tongue

Here's hoping

I was able to find a couple of my most precious files... my index.html and style css for my website. Lots of me went into those... they're not the latest iteration, but at least I can work from that. Tomorrow I'll work on the wallet.dats.

Hi!

Here are the sig for DB Berkeley (wallet.dat) add it to photorec and run it again...

Code:

dat 0xc 0x88090400

Science

Sweet! So I do have to run it again... guess I'll go ahead and stop this session. Before I do though, I want to see if FaSan's method of using keyhunter is faster than Photorec. It's been running now for 17hours and says I still have 6 hours left. I'm scanning the entire disk.

EDIT - this might be a stupid question... do all wallets use this signature, or will this only find my bitcoin wallat.dat?

So I've already ran Photorec (this is second time around actually - 6 hours left). Do I have to run it again so that the wallet.dat signature file can be included in the recovery? I was under the impression that maybe they'd be in the 1mil files I got on the first run, just perhaps a .txt format....

Didn't you get a backup in the external drive? then just run (assuming you are on ubuntu now)

Code:

grep -RH 'defaultkey' EXTERNAL_DRIVE

Against your backed up files, and it will get the wallets for you no matter what their name/extension is.

(And put the real path of the external drive instead of EXTERNAL_DRIVE)

Ah! Yes, Photorec saved all of my copied files over to my external drive. But because they're a default file signature type I was asking whether the wallet files were recovered to begin with. It looks like you have to add a custom signature prior to running Photorec so the files can be included in the recovery:

import every private key to every wallet. you can import keys using RPC or command line so it shouldn't be too tedious.

Holy crap - didn't know this. Man you guys are going to take my bitchange, lol. But it's cool

Holy smokes! So this will actually rename them to wallet.dats for me... and I can then use Newar's suggestion to peer inside the files to see addresses/labels maybe? Do wallet.dats have the coin name mentioned in them? that could help.

So to use this, it looks like I have to install fidentify? Can I assume that the wallet file extension was also located in the /usr/share/misc/magic directory as well?

Perhaps I should've mentioned that after I copied all files to my external drive, I reinstalled unbuntu... don't ask me why I didn't just take the damn hard drive and confirm the files were there before doing that. Coulda, woulda, shoulda doesn't help me now, it was an oversight, I was tired as hell. Anyhoo, I guess that's why Testdisk couldn't help me and I had to use Photorec.

Simple start it and wait. After take the list of privatekeys founded and re-import on another wallet. If you lucky, you take back all your bitcoins.
