I found a bug in the HDF pathway in gasdf.c :
Near the end of the gadsdf() subroutine, the varids in the gavar  
structure for each variable are reset to -999 so that the undef  
values and scale factor/add offset values will be retrieved in the I/ 
O layer. I did it for ncvids, but not sdvids. Add the 2nd line below  
and see if that isn't a workable short term fix.
         newpvar->ncvid = -999; /* reset the varid so undefs will be  
read in gaio.c */
         newpvar->sdvid = -999; /* reset the varid so undefs will be  
read in gaio.c */

There have been other patches to gasdf.c in the past week, as well as  
other unrelated bug fixes, so that one change may not fix everything  
for you. I will be putting out 2.0.a1 pretty soon.
