Hi,

in last days I have met with similar issue. It looks like CW issue for this sector.

Could you please read the data from the sector by code step by step to check content at addresses 0x100000...0x1000FF?
BTW, there is another approach to read the memory. You should use another option to view the memory.

Go to option:     Window->Show View -> Memory Browser

 

The difference address 0x100000:
