Well, I low-level formatted my drive by installing Solaris and running the SCSI Command Utility (scu), available here:
This program runs on several platforms listed below. I obtained the desired results with this program and you may too.
scu runs on: Linux Alpha, Linux Intel, Linux IA64, Windows/NT, SCO UnixWare 7.1, SCO UnixWare 7.0.1, HP-UX IA64, HP-UX PA-RISC, Solaris Intel, Solaris Sparc.
Read the documentation thoroughly before running this program, as with any program that mucks with your hard drive(s).
