thx a lot for your suggestion of checking the code of tiffdump. 

in fact, i had something like this in mind - i'm pretty sure that this will 
help to get the information about the ifd itself i'm looking for.

the idea is to have a >single< tiff-file with a backup of the ifd, which is 
originally/usually used. >if< something is wrong (which i should know by 
comparing the values): overwrite the 'damaged' ifd with the values of the 
backup. there would nothing wrong about overwriting the backup ifd.

referring to:

hm... but how? i still couldn't figure out. [ right now i start feeling pretty 
stupid :) ]

thx again for your help. /karin
