Hello, I dont know if this section is the place for this question but is there any chance to retrieve a lost wallet?
my computer got virus and i formatted it, i backup all my bitcoins to paperwallet, but i forgot about my wallet that i use to receive payment from bitmixer, i only got the address but the wallet identifier and the secret words is lost btw
1-Stop using that hard drive.
2-Get an external HDD case.
3-Put the HDD into the case and connect to a computer with large amount of space available.
4-Download getdataback.
5-Assuming its finding "formated" files browse to Users/user/AppData/bitcoin/
Electrum: Users/AppData/Roaming/Electrum/wallets
Linux: /root/.bitcoin
6-Copy wallet.dat (Electrum: default_wallet) to your current OS.
(if getdataback is trial you cant copy but you can view the file, select all and create a new file with this content, this will work if its an electrum wallet if its bitcoin you need to somehow copy the hex data instead of the ascii and use eg HxD to generate ascii from hex).
7-Go to the same folder, windows/linux/electrum, and backup your current wallet.
8-Paste the recovered wallet in there and run bitcoin-qt/electrum.
9-If the data is not corrupted your done.
EDIT: Just noticed this was a blockchain.info wallet so I guess it doesn't apply but ill keep the answer here so it can help others
