Thanks for all your help, Arno. I've learned a lot in the last few days, and am grateful for your time in helping me.

This will behave exactly the same as with a non-encrypted device.
The encryption layer just translates the raw encrypted device into
a raw non-encrypted device, which for all intents and purposes
(except performance) can be treated the same as a non-encrypted
device.

The filesystem sits on top of that and difficulty-level of
recovering deleted files depends on the filesystem used.
For example, with ext2/3 it is pretty difficult, but you
may find fragments easily if you know what you are looking
for. With FAT is is generally easy. BTRFS, XFS, ZFS, etc.
I have no idea.
