liife threw a tempest at you? be a coconut !
i will definitely try even though im having the worst luck, thank you for trying to help me.

I hope you aren't posting from the harddrive... keep us updated! would be nice to hear a success story. Sadly I don't remember which recovery tool I used. but I did some searches and looked for guides. I took a major one where I could input the type of file I was looking for. I hope you will find your wallet.dat.

T_____T Yeah it seems like im gonna have to take this Loss and use this as a lesson to backup EVERYTHING i do in cryptocurrency on a flash drive. its a good amount i lost but ill just have to never let this happen again it was totally my fault, i just wish it wasnt because of a fucked up video driver update... rediculous timing too it could have happened after the pandaminer sale and i wouldnt care.

frankly there is still hope (little) but don't give up before trying a recovery tool. the program will look at all sectors of the harddrive and try to recover everything. I did it in past and it worked well. then it's about luck. at least try.

yeah basically, i have two hard drives and the windows 10 was my primary now that is still messing up for some reason, i reinstalled win10 pro and everytime it starts up its stuck at a black screen, so im using an old win 7 on my 2nd hard drive, i shouldnt have formatted my primary hdd but i could barely get into win7 so i didnt know it would work or not and i was in a rush to get win10 back up and runining, now ive backed myself into a loss of bitcoins and loss of possibly getting a pandaminer.

OK... So first things first: make sure you are not booted from the harddisk that contained the wallet.dat, do not write any data to the harddisk that contained the wallet.dat and try one of the many available utilities that are designed to recover files that are deleted/formatted.
If we are talking about a lot of BTC, i'd personally unplug the harddisk, and use dd to create a complete copy of all sectors on this harddisk... Then i'd try to restore it myself. If i was unable to do so, i'd try to hire a professional. If we're not talking about a lot of BTC, i would omit the last step.

BTW: I just realised your title said you were using bitcoin core... sorry  Smiley

Basically, if you want to recover your funds, you NEED your wallet.dat. No wallet.dat => no funds... password+address are not sufficient to restore your wallet...

Exactly!!! unplug! don't write any new data and pray that the sectors in questions haven't been overwritten. Then like mocaninno said use a harddrive recovery tool and search for a .dat file. Good luck.

And next time, before doing any move ask!!! AND BACK UP BACK UP BACK UP!!!!

i have a hard time following you... What happened exactly?
We need to know:
1) which wallet you were using (core, electrum, multibit, an online wallet,...)?
2) did you reinstall your os, or did you manage to fix the running os?

If my suspicion is correct and you were using a desktop wallet, crashed your windows and reinstalled your OS => immediately shutdown your pc.

In case you lost core's wallet.dat, and you only have the password you entered to encrypt your wallet + the address, there is no way of using this information to restore you wallet... If you are talking about a seed, you should be fine, if you are talking about an online wallet => it depends on which one

Is there is anyway to recover a wallet that i wasnt able to backup from a corrupted hard drive? everything was fine yesterday on my pc until i tried to update my video card then it just stalled for hours so i restarted and then windows just kept freezing cause video driver corruption. i tried to save as many things as possible but couldnt get into windows to backup my wallet at all. now i have windows working and have no way of getting my old address back, i have the password and address if that will help.

What did you do? format and reinstall windows?
