Chuck, I don't doubt that you are right on your math, I was just hoping for something in the Ballpark. When I started to do the math I realized I'd forgotten how to deal with the large numbers hadn't done it in 20 years. IIRC (and that seems to be doubt :(^) there is a technical reason for the 1024 and it has been with us since 64k system. Remember how we could do with just 64k of memory on the mother board.

There's an error in your math. 1 gigabyte is 1024x1024x1024 = 1,073,741,824. Multiplied by 196 that's 210,453,397,504.

The difference between 1 billion bytes and 1 GB is approx 7.4%.

It was the disk drive marketers who started all this crap.

I forget what all the usual increments are since digital 1000=1024
bytes, but 196GB (a usual increment) is 200704000000 gigabytes, but why.
I like Piers idea its a nice simple explanation bad sectors.

I don't do Amazon any longer, so I just took a quick look, there prices
lessor memory cards. Sounds like your getting stabbed by the
conversion or
amazon. I thought 200 was strange, but I haven't bad sectors in
sometime. I
haven't any transfer speeds on SD and microSD cards. I just replaced
the SD
in my PEN with a wifi SD & microSD the AG1 told me to do it.8)
And life is so much better, isn't it?

Me thinks that those 200Gb cards are actually 192GB.
