Stop Bitcoin Core. Go to the Bitcoin Core data directory. Move the wallet.dat file in there to a safe location. Copy your original wallet.dat file (the one that you want to use) into the data directory. Start Bitcoin Core again.

Then your wallet.dat file is on the external hard drive. Bitcoin Core's wallet will not function without a wallet.dat file. Either you provide one or it makes one. If it makes one, it will not be the one that you want to use.

What kind of wallet is it (what software)? What do you mean by changed its address? What do you mean by synchronizing? What did you get from the wallet that you input to blockchain.info?

Its the bitcoin core qt wallet. It has to be synchronised to send and receiver btc. I had it for 4 years on my external HDD, however wen i
transferred the wallet to my laptop i noticed that the amount of bitcoin was zero and the adres had changed. I checked the old adress on blockchain.info.com and the amount of btc never changed since 2013.
