You could put a GPT partition scheme on the external USB drive, create one large partition, encrypt the partition (optional), put the partition into a ZFS pool, create one filesystem inside the pool, and set the 'mountpoint' property on the filesystem (ZFS does not use /etc/fstab). Use the filesystem like any other Linux filesystem. If any bits rot, ZFS will detect them. Do a "scrub" periodically (e.g. monthly).

I did some more searching for ZFS on Wheezy. See the second FAQ item:
https://wiki.debian.org/DebianWheezy
Add this line to /etc/apt/sources.list:
deb http://archive.debian.org/debian wheezy main contrib
Then run these commands:
# apt-get update
# apt-cache search zfs
Look for "zfs-dkms".
