So it was the file size issue then?

Reading out of the MMC to the I2C takes ~3 seconds for a 512 sector. I'll be getting it faster by coding for loading the 16 byte buffer on the I2C.
Post some code. I'm sure there's a way to make it faster... It only took my code about 7-ish seconds to erase a full 24LC256 (32Kbytes), while displaying the current address on an LCD.
