Try #shred --help
after booting from some kind of SA distro, like GRML.
Increasing the number iterations then using the -z option to zero is
thorough.
Modern hard drive IDE's map logical sectors to physical sectors and can
make adjustments automatically. I don't know to what extent this affects
data destruction using operating system level tools.
Linux LUKS is a oss way to encrypt partitions. Have not attempted to
shred a LUKS protected partition yet, I do know encrypted partitions
need to be cloned at a byte level.
Magnets and heat will distort the magnetic orientation of the disk
platter which constitute the bits of storage.
