Hi Sajid, The "crosshair" on the images is the tile join between the four tapers, and is a standard feature on all ADSC 4-tile detectors. I am certain HKL2000 should know about these - certainly mosflm will simply ignore the image there.
Any image from the same detector should have the same features. The ice ring may have more to do with your high chi squares... processing only data within about 4A should give you a much more self-consistent data set.
