The most likely problem is that you're using the wrong planar configuration. TAG 284 (TIFFPLANARCONFIGURATION) should have the value 1 (contiguous). In the "bad" file you have it set to 2 (planar).
The TIFF Class F document (March 1, 1992) also recommends that you write the files in multiple strips. (Older viewers based on 16-bit code might not be capable of reading strips larger than 64kB).
