Topic: The wallet I have only made one pair of keys (2010) (Read 260 times)

You shouldn't be using a very old version of Bitcoin Core. If you use a newer one, the default is 1000 keys.
In the Console (under Debug window), enter getwalletinfo. Mine shows this:

Either way, make backups once in a while!

The wallet that I used was before they done the 100 keys, that's why I would like to make more in case change is sent to them,

You are right about transfering the wallet.dat to a new computer, however, a wallet.dat from 2010 does not contain a mnemonic code.
Nowadays, a default wallet generated with core is HD, it still doesn't have a mnemonic phrase. Back in 2010, bitcoin core wallets were defenatly not HD, they just generated random private keys. These private keys were stored in the (hopefully encrypted) wallet.dat. This is why you had to backup your wallet at least every 100 transactions, since default, 100 private keys were pre-generated (IIRC).

@OP: like many people have already said: you can just copy your wallet.dat to a safe place, then move a COPY of the copy to a new pc... You don't have to wait for your bitcoin core wallet to sync tough: you can just export the private keys and import them into a sync'ed wallet (or an SPV wallet like electrum).
A last option would be to use db_dump or https://github.com/jackjack-jj/pywallet to export the keys directly from the wallet.dat, this will save you a lot of time and diskspace

Last remark: since you're talking about a 8 year old wallet, there might be compatibility issues with modern versions of core (i really don't know), that's why it's important to keep at least 1 master copy of your wallet.dat in a safe place. I think pywallet is incompatible with more recent versions of the wallet, so it should probably work on really old versions.

Good luck!

Yes, you can attach the hard drive to any computer. The content is what matters

Information is stored in a hard drive, not in any other part of the computer.
So, yes, you can swap the hard drive and insert it in another computer.

What particular wallet? It's from 2010 so I assume it is a Bitcoin full node.
The wallet.dat contains your mnemonic code that was used to make that one pair of keys. So,
There will be no issue in generating new keys wherever computer you want to transfer the hard drive or wallet aside from the compatibility (if there's any)

Can I take the hard drive out and put it in another computer to make more keys, or does the wallet have to be opened on the same computer that made the first set?
