...which would be me. I was referring to the rebate, not the drive itself, in case that's what you meant.
Anyway, I emailed the address on the rebate website and attached my scanned image. I'm also working with USPS to try and track it down, but I'm thinking it might be a good idea to mail a copy to them, since it has to be post marked by the 31st.
Wow I didn't think they ever lost certified mail.. that sucks.
