What is the best (easiest) way to overwrite old harddisks with random garbage ?

Have a look at shred - 'man shred' will explain how to use it...

LOTS of caveats there.

Most data which is that valuable is also being kept on
journaled filesystems and probably RAID, too...both of
which violate shred's assumptions.

If you do something like 'shred -v --iterations=10 --zero /dev/hda', why does journalling or RAID (or indeed which filesystem was previously used on /dev/hda) have anything to do with the effectiveness of the shred?
The original poster was asking about how to wipe an entire drive (?), not trying to wipe one file at a time.
