test disk from cgsecurity versus data security

[Peter_22@xxxxxx]

Hi!

Just today I saw "test disk" from http://www.cgsecurity.org/ while being at
work.
I didn´t run it at home on my own disc but my question might be a serious
concern.
As "test disk" is able to restore overwritten/shredded (dev/urandom) or
erased (dev/zero) partitions, how secure is encrypted root as aespipe reads
data from one partition, pipes it through aes and writes it back to the same
partition?
In case you can restore a shredded partition with such a tool, what can you
do with data encrypted by aespipe???
This has nothing to do with watermark or code attacks. It´s just the fear
that someone could recover all data in a state *before* it was piped through
aespipe.
Is this a real problem or just neglectable?

Regards,
Peter
