I have been fighting with the same problem but have only just found that
it has been discussed here. In my experience it does not seem to relate
just to the working directory or its partition - directories shallower
than the appliaction directories give erroneous results as do other disks.
It seems not to be just a 'programming' problem, since the same HDF file
moved around to different directories is variably readable or unreadable.
Also the space-in-name hypothesis seems not to hold since changing the
disk name does not save the situation, too bad :-( Interestingly, a file
looks ok if it is re-read during the same session in IDL but is not usable
if you restart the application. Has there been any more progress here. It
certainly makes using HDF files on a Mac difficult which is too bad since
they are just what I need right now.
