Moving data to container is secure?

Suppose that I have an external hard drive of 500GB, and of this total i am using 100GB of unencrypted data. And suppose that i created a container with 110GB inside him using AES encryption.
My question is: It's possible move the unencrypted data to inside the container without leave traces of their existence?
Or the unencrypted data remains recuperable even after moving them to container?

you have to securely delete the unencrypted data or wipe the free space.

So... the old data remains recuperable even after move them to container? Right?

in general yes.... unless you wipe it appropriately etc...

it is actually very hard to wipe it appropriately, if some data was there ever stored unencrypted, some parts of it could be recovered. Sometimes even file name can be used against you and file names are very hard to destroy on journaling filesystems. Good software is privazer, but better would be to place your container elsewhere, overwrite your external hdd with zeros (with killdisk etc), format again and place the encrypted container back. Only then you can be sure previous data are away.
