I've just upgraded my IDE drive to a couple of SATA ones running in RAID 0. I have someone interested in purchasing the old one, but am uncertain of how to securely wipe everything off it. Will formatting and partitioning it be enough, or will the data still be recoverable? Remember, this hard drive has to still be useable, so no crazy ways to destroy a hard drive please! 
Any ideas are appreciated.
