I plan on reformatting my main drive. I did this once before and of course lost access to my Bitcoin Core wallet and the Bitcoins therein.
Does anybody know how I can go about transferring my Bitcoins before or after I reformat my drive?
Can I just copy and paste the Bitcoin Core folder to my second drive before formatting, and then transfer it back afterwards?

You can just copy your wallet.dat from your local wallet directory. If using windows it will be in %appdata%/Bitcoin. After reformatting download a fresh copy of Bitcoin Core and replace the wallet.dat with the one you saved prior to reformatting.
There's also the method of using the backupwallet and importwallet commands. https://bitcoin.org/en/developer-reference#backupwallet
