this is becoming OT, but I can't recommend storing HDDs as "real"

backup solution either. HDDs _do_ have bitrot, and one should at least,

say, once a year, verify that the *whole* disk is readable, ensuring that

sectors which are not yet completely unreadable get remapped. Vaulting

a DVD or a HDD for five years or more leaves you in both cases with the

real possibility of data loss.
