You can export your passwords to a plain text CSV from the original computer.

As a general rule, I expect a file on an encrypted disk to be encrypted with a key derived from a password I provide.

		I think it's time to update your expectations. Hardware security modules have been around for quite a while. You shouldn't assume that your chosen password is the only input to the key derivation, or even that the raw key itself will always be obtainable.

As a general rule, if I'm the user of both disks I expect to have the encryption key(s).

The right way to do that is FDE, where you can't even mount the filesystem to see the files without having the decryption key.
