With a tiled TIFF or different compression schemes, the file is recognized
as TIFF and gets a more useful error message ("unsupported compression
scheme", "unrecognized storage method", etc.).
BigTIFF does have the disadvantage over all previous changes in that it will
get "Not a TIFF file" or "corrupt file" error messages from all previous
software.
That is a real concern for many users, and what lead Adobe to use .psb
instead of .psd for the 64 bit offset version of the PSD file format
(despite being the same format internally).
