His situation needs honesty more than optimism. Five years ago, sending part of a bitcoin from an exchange to a wallet, the computer was reset mid-setup, so "we didn't get any wallet.dat files." The coins "can be seen at the public address", but having "trauled the hard drive" they found nothing in the wallet files, and can send the drive or a copy. This turns entirely on whether a wallet.dat with the right keys was ever created and written before the reset — and the honest likelihood is low, because a wallet interrupted during setup may never have generated the file at all.
| Media | Hard drive (or a copy) from a computer reset during a bitcoin wallet's initial setup — no wallet.dat found; coins visible at the public address but the private keys sought. |
| Reported situation | Bitcoin sent from an exchange to a wallet five years ago · computer reset mid-setup while the wallet software was still initialising · no wallet.dat file obtained · coins visible at the public address on the blockchain · owner's own search of the drive finding nothing · drive or image available. |
| Fault class | Sought recovery of a wallet key file that may never have been created — the question being whether a wallet.dat was written before the reset and survives as a deleted remnant, not a drive fault; honest assessment central. |
| Equipment used | Drive or image examined under a hardware write-blocker, all work read-only · a thorough search for wallet.dat and its remnants in R-Studio — deleted files, unallocated space, and file carving by the wallet format's signature · any partial or overwritten wallet structures assessed for usable key material · an honest report of whether recoverable key data exists, with no assurance of coins where the file was never written. |
The crucial question is whether the wallet file was ever created, and honesty starts there. A wallet.dat holds the private keys that control the coins — and it is created by the wallet software during setup. If the computer was reset while the wallet was still initialising, before it generated and wrote the wallet.dat, then there may be no file to recover, because it was never created. His describing the reset as happening during setup is exactly why this is the central uncertainty, and why the honest likelihood of recovery is low rather than high.
Coins visible at the public address do not mean the keys are on the drive. That the coins can be seen at the public address confirms the transaction reached the blockchain — but the blockchain shows balances, not keys. Spending the coins requires the private keys from the wallet.dat, and those are only on the drive if the file was created and written there. Seeing the coins on the chain and having the keys to move them are entirely separate things, and it is important he understands the difference.
Recovery can search for the file, but it cannot conjure keys that were never written. What a laboratory can do is search the drive thoroughly for a wallet.dat — as a deleted file, in unallocated space, carved by its signature — far more rigorously than a manual search. What it cannot do is recover a file that was never created, or generate the private keys independently. The honest boundary is clear: we recover files that exist on the drive; we do not produce keys the software never wrote.
The honest prognosis is delivered plainly, without false hope. If a wallet.dat was written before the reset and survives on the drive, a thorough search can recover it and the keys with it. If the reset happened before the file was ever created — the more likely case given the timing — then there is nothing to recover, and no technique changes that. Which is true is established by the search, and reported honestly, with no assurance of recovering coins where the file may never have existed.
The drive or image was examined under a hardware write-blocker, all work read-only. A thorough search for wallet.dat and its remnants was run in R-Studio — deleted files, unallocated space, and file carving by the wallet format's signature — and any partial or overwritten wallet structures assessed for usable key material. An honest report was given of whether recoverable key data existed, with no assurance of coins where the file was never written.
A thorough forensic search for the wallet file and its remnants, and an honest report of whether any usable key data survives. The diagnostic costs nothing and completes within two working days of arrival, and the quote is one fixed written figure with VAT already in it; if the data can't be brought back, no charge is made. The decode: this turns on whether a wallet.dat was ever written before the reset — and if setup was interrupted first, there may be no file to find. Coins on the chain aren't keys on the drive. We search thoroughly for the file, but we can't conjure keys the software never created.
Understand the honest limit: recovery searches for a wallet file that exists on the drive — it can't create private keys the software never wrote, and coins visible on the blockchain aren't the same as keys on your disk. If the wallet was interrupted during setup, the wallet.dat may never have been created. Stop using the drive so any deleted wallet file isn't overwritten, and don't trust services promising to recover coins as opposed to files. A thorough forensic search is worth doing, but expect an honest answer, which may be that there's nothing to find.
