For a long time I had gotten occasionally a funny magenta or purple image with my iXpress or Imacon / Hasselblad digital backs on my Rollei 6008AF body.  I figured that sometimes a file just gets corrupted or hit a bad spot on the memory card or there was a loose cable, but on one occasion I had a number of these purple files in one shoot.       I sent some files to Hasselblad Support a few years back and Paul Claesson wrote a very informative e-mail with the explanation.
