Windows reinstall

[palinko]

Can anyone help me? I now reinstalled my windows, and installed bitcoin client, but I can't see my 1.03 coin in my wallet. I have one of my old wallet adress, how to recover coins?

Where is your backed up .dat file?  You did back up the .dat file right?

[Accountant]

lol. unless u made a back-up, its gone bro

[palinko]

lol I have no backup date, partition resized + formated

[bitcoinvideos]

You can use the windows program recuva and do a deep scan for the file.  You might get lucky.

[Akka]

If you haven't made a backup of your wallet.dat File your coins are gone and nobody can help you.

Your address will only enable you to view you lost coins, sorry.

If you made only a quick format and not a real one, than there is still (very, very little) hope, with using a recovery tool. In that case don't install anything or copy any files. Don't use any discspace until you have gone over it with such a tool.

Try http://www.piriform.com/recuva as stated above and try to find a file called wallet.dat

There is a tool (at least one) that will scan a formated hard drive for bitcoins, it is not guaranteed either.

I used it and recovered most of my public and some private keys, unfortunately not the ones holding the bitcoin :|



I used a linux tool, but I'm sure there's a windows one, if not, make a linux boot thumbdrive and D/l it.

I am quite sure this was the one I used:

Hope that helps.

There is a good chance the data is still there, but the metadata (filename, timestamps, etc) is certainly gone.  The above tool will help, but you should shut everything down and boot up a linux cd or thumbdrive.  Do not write to your disk at all or you risk overwriting your keys.

The address is only the public portion of the key.  It is the private part that you need to recover to be able to spend the bitcoins.

[bitcoinvideos]

Yes it is quite possible the data will end up being corrupted anyway.  Speaking of which...time to go make an extra backup lol.

[palinko]

didn't found wallet.dat
so that was it maybe the linux thing

[bitcoinvideos]

Sorry man that totally sucks.  Give the USB bootable drive a shot and see if there is any low level recovery you can do.  Although figure in how much time vs effort = reward this is worth.  Can you make more than $12 / hour doing something else? If so do that and chalk it up to bad luck.

[palinko]

bitcoinvideos. hah, that linux thing can't work for me

Your viewpoint is great! But in my country I can do 11$ / 10 hour work so I think I should give another few shot for this

That blog post isn't quite right....

sudo rm wallet-recover
wget http://makomk.com/~aidan/wallet-recover
chmod +x wallet-recover
sudo ./wallet-recover <device> recovered-wallet.dat

where <device> is your hard disk (likely /dev/sda if you only have one drive)
