Thank for your help.
The Wang/Kodak save the tiff that is not TIFF/F class.So i must convert it to TIFF/F class again.

All this means is that Wang/Kodak (and by that I assume you mean the horrible Windows Imaging tools) has recompressed the file and written it out in multiple strips, where you originally had it as a single strip.
Now, what's the problem?
This file should still be readable (even if some from Wang tools are not).
Why are you trying to change the stripbytecounts and stripoffsets again?
