Could there be on this disk that there is one Linux install AND one Windows install?

And that for some reason we only see the Linux instance when using and external disk reader. So that the Windows instance is hidden from us.

But that somehow even if its hidden, some files like those Electrum files still show when doing searches on the disk.
So that the Electrum instance and wallet is somehow on the hidden-Windows-part of the disk and I need to figure out how to access that somehow.

Aha   this is an old Ubuntu instance, I will look for how to see hidden files in Ubuntu.

I have updated the document with one more photo/screenshot of /users/   there is only one user  "ha**"  and then what comes up when I click on that.

There is no .bitcoin  or  .electrum     but as you say I must figure out how to look for hidden files.

Good progress.

Aha very interesting, so this old laptop  (it was a very very small micro machine) probably was a Linux machine then.

In that case try to find where the wallet would be on a Linux machine.
But the weird thing is that I cant seem to find where the Electrum folder seems to be. I can only find those files as a clue that there should have been Electrum on this machine.

Ohh my bad here are the screenshots open.

This was a mini-micro computer and I had to break it up to reach the hard drive. Maybe maybe it can be reassembled, but unlikely.


Also maybe this was actually a Linux machine, I do not remember how I used it.

I have tried to read the drive on Windows, did not work. On Mac did not work. But my old Ubuntu was able to read the disk 159 GB.

Here are some screenshots of what comes up when I read it.
One is the icon for the Electrum.
I do have some vague memory of installing Electrum on this.

If these screenshots give any ideas of what this might be and how to go about much appreciated.
Maybe a trained eye can see if this is Windows or Linux or what it is.

I have now found an old drive where Electrum was downloaded and installed at some point, around 2014.
I removed that drive from my old PC hardware, but I regret that now I should have tried to start up the pc instead. But it can not be reassembled as it broke when I opened it.

I can find some of the Electrum files when I search the disk.
But I have not found a wallet file connected to Electrum.

How to go about this.
Is there a way to actually boot up, start up the old Electrum app from the hard disk and then it will itself find its wallet.

Is there a default location for wallets.

Maybe I can make some screenshots of what I see on various searches "Bitcoin" "Electrum" etc to see if anyone gets any good ideas.

Big thanks.

thanks, I have some 15-20 old drives.
First I will find the one with Electrum on it and then start searching.


I am working on one disk now, it would not open on Windows but I can browse it with Unbuntu.

On it I found one wallet.dat file I will test (rather exciting to see).

But also;

appcrash_bitcoin-qt.exe
bitcoin-qt.exe
bitcoin-0.8.1-win32.zip
bitcoind.exe
bitcoin_testnet.png (green bitcoin logo)


Might all that be something interesting, to warrant further investigations. Or should I be fine with the wallet.dat file.

Thanks

thanks

I know I also have at least one instance of electrum on one of my old disks

Is there a similar file to wallet.dat to search for to find Electrum wallet

thanks

Hi,

Im going over more old hard drives, I a bit of weird testing in 2010-2013.

When doing search for "wallet.dat" and "wallet" from old Windows hard drives (on external disk reader now) I am finding files such as these:

Apart from the
wallet.dat file / files


wallet.cpp
wallet.h
wallet_tests.cpp
walletdb.cpp
walletdb.h
walletmodel.cpp
walletmodel.h


Should I investigate those files extensions, might there be something of value there.

Thanks

Final update on this issue.

It seems everything has gone well on this issue.

I was able to extract the private key for all the relevant accounts in Bitcoin Core, import those privat keys into Electrum, see the actual-real-balance and then send off the bitcoin to the Ledger account.
Great!

Some issues;
It turned out that what I though was different Balances was actually partly the same account counted in several Balances in several different wallet.dat files
So in all it was much less Btc than I hoped, but what was actually there corresponds with what I looked over in my notes from back in 2014 when I saw it last.

How my various wallet.dat files got mixed up I do not know. I feel there is a security issue here somehow. Its up to the technical guys to evaluate that.


The Btc balance I was able to recover in the Bitcoin Core by witdrawing/cancel transactions from 2014 did not actually work. The balance was not affected as those funds were never withdrawn in the first place.

I have not yet done the job of getting the Forkecoins, but I will do that and have gotten good advice on how to.

ALL in all very good, I was able to recover some old stuff. Big thank you to community.

I am very happy to tell you it looks like this works. Importing the private keys to Electrum.

I started Electrum and set up with private keys (did not set up a new wallet on Electrum. So I guess this WAS a sweep.)

And was able to send that balance off to my Ledger.

Very nice.

Question,
Should I wait with doing the next bitcoin adddress until Electrum has confirmed the transactions, the send of the bitcoin out of the wallet before I close it and do the next?

When I do the next address. Should I delete Electrum and reinstall Electrum each time (to avoid the same problem that I had with BitcoinCore).

Good good.

I think I consider all my wallet.dat files compromised.
So I think not to "sweep" in, but to open it and transfer it to my Ledger.


I will try this now. Downloading Electrum from electrum.org

Will let you know.

Thanks.

LoyceV Yes I am able to get the private keys dumped. Got private key dump from two addresses now.
(A bit paranoid as to how to temporary store this private key. Once dumped on screen I probably should consider things compromised and work hard to secure this promptly.)

My new MacBook Air only has 256 GB disk so I have ordered a new WD SSD 1TB hard disk that I will pick up later today. So I might do the entire new download on that disk, this will take a few days again to do this.

It seems maybe trying something with the private keys might be a better option.
How do we suggest to go about it to restore with the private key.

I am familiar with the Exodus app on MacBook desktop, seems there is a way there to import private key there.

My end goal is to move all holdings of Bitcoin to my Ledger Nano S hardware wallet.
I assume I will have to make at least one send transaction for this.
(As I have been working on these 3-10+ different wallet.dat files now for some 1-2-3 weeks using various different hardware (old disks, disk readers, 3 Macs) I probably should consider all of that compromised and get all off to hardware wallet.)

I now see that at least ONE address with bitcoin is present in at least two of the three wallets.

Need to go over this carefully.

I have now run listaddressgroupings on all my 3 accounts. And checked all addresses against Blockhain Explorer.

And there are discrepancies on all 3 accounts.

So it seems likely this is the problem.

Question is then I assume how to repair these acccounts/wallets/wallet.rar files.

LoyceV I just sent you a PM with the results, the 5 addresses.

I have tried to look at Blockchain Explorer but cant figure this out.

Please note that I am working on 3 different wallet.dat files with various contents. And in the posts above they are used several of them.

I just did the listaddressgroupings

I got 5 addresses
4 are empty
One with the same Balance as the Bitcoin Core says Balance.  Currently Btc 0.48

I am now trying to send some BTC to the wallet.dat that was created when I sat up the latest Bitcoin Core on the brand new clean MacBook Air.

Once hopefully this Bitcoin reached this account I will try to make a send.

Sorry for being a bit repetitive but I just did one more try.


My accounts starts at Balance Btc 0.170826

I make one small send of Btc 0.000226. I say to have the fees included. I use the default transactions fees of 6 blocks and the suggested fee.

Then I get the confirmation box. I confirm.
(Question: In the confirmation box the Transaction fee is written IN RED. Does that mean there is something wrong? That the amount is too small or similar?)

When I then go to the account Balance now says Btc 0.007597.
So that MORE THAN Btc 0.17 has been mysteriously pulled out of the account to make this small transaction! Crazy.

So I then go to the que and I Abort this send.
Then when I go back to Balance. It is back to the original Balance of Btc 0.170826 again.

Why is the Bitcoin Core almost entirely emptying my wallet every time I try to do a simple send.
And this happens over 3 different wallet.dat files.
So strange. And it seems to be different amounts pulled out every time.

As said,
This happens on 3 different wallet.dat files.
On two different MacBooks two different fresh installs of the latest BitcoinCore.
One MacBook is completely new fresh for this specific purpose, nothing mysterious on it.

Very very strange.


Here are the screenshots of this latest attempt:

I am having trouble with Send in Bitcoin Core.   (I have a separate thread for that but that thread is getting a bit technical now).

Much want some help with just the very core basics.

When it comes to:

Is that default ok for most "Send" transactions? Or does it have to be adjusted for most people, most transactions, for everyone?

Transaction Fees.
There is a default recommended 0.00004978 BTC/kvb Estimated to begin confirmations within 6 blocks.

What does this really mean?
Should one go for 4 or 2 blocks?

(I am willing to pay to get this done now, do not care about USD 20-50-100 transactions fees. Just want it done.)

Or is it better to go with Custom per kilobyte. Is there a risk with that?

Any advice appreciated.
