Not if you use an encryptor that stores information about the file to which a
block belongs to and the block number. Sure, you lose some of the bytes for
each block, but it's safer.
i.e. have the fist 12 bytes of each sector contain:
[4] inode number
[4] this is block number
[4] timestamp (incase multiple copies are found.)
That way the recovery dude only has to look at the first 12 bytes to link the
files together. Of course you must have some way of dealing with empty
sectors, possibly zapping the 1st 12 bytes so that the recovery dude doesn't
charge you for recovering empty space.
