Don't believe people telling that. The data will still be recoverable (with the right hardware). That is so because overwriting a "0" with a "0" will lead to another level of manetic field than overwriting a "1" with a "0". The only way to wipe out data safely is to write different random bit over it several times. > but couldn't the data be cached elsewhere on the drive, especially > with journalling filesystems?? Journalling filesystems are a problem when it comes to wipe out single files. Wiping out the whole harddrive is still possible.
