Wow, another correction. I just pulled apart a JAZ drive and they are about 9.4cm in diameter. The ones I was using were either pulled from a ZIP 250 drive or from an old 2.5 in. laptop drive. Sorry I goofed up. Hard drive platters in general should prove a decent mirror. I have some old 340MB Drives laying about collecting dust.... <img src="/images/graemlins/smirk.gif" alt="" />
