you format, then fill the drive with 0's, format again, then fill it with 0's again, and format once more.
make sure to delete the file system and all partitions each time.
the NSA/DoD do this exact same thing, except after all that, they smash the HD's, then burn them, but since you want to give em away, thatll keep you safe.
the point is to overwrite any remenants of data that are left behind on the hard drive even after delete, until something comes in and needs the space which then overwrites the left over data of whatever deleted files, so your basically deleting everything, then overwriting all remaining info with 0's, then getting rid of all that, then overwriting everything with 0's again, delete it again, and re-create the filesystem and partition.
