Compact Flash question

You might wear out the first few MB if you only shoot 2 images then take them off the card, but that's another issue.

Not even then, because the CF controller uses wear levelling to spread the load over all the memory areas.

Worrying about 'wearing out' a CF card is totally pointless. As you say, you'd have to write somewhere between 8 and 800 TB. That's around half a million images. If you shoot 200 images a day, every day, your card would wear out in around 5 years. Is anybody still using memory cards that they bought five years ago? If you are, and you shoot 200 images a day, then you may want to think about replacing it. Everybody else can just ignore it as pure FUD.

My post production includes copying the images on my CF card to a pair of external hard drives and then reformatting the card - EVERY TIME I USE IT...

I'd not be so sure abotu wear levelling in a CF card - some have it, some haven't.
But I'd still not worry about it.

Really!? I'd be very surprised if that were the case. Do you have any evidence for this being so?
