Some things to check:

You might not have access. What are the file permissions, owner, and
group membership?

The file may be corrupt. Can you view the HDF file with ncdump, or
similar utilities? Can you open it read-only, and view its contents
using HDF_SD_GETDATA?

Is this new code, or code that has already worked on a different file,
but is failing with this one?

You imply that you've already collected the following information, and
that it checked out OK, but maybe you've misinterpreted it - could you
tell us:

What values does HDF_SD_GETINFO give you for DIMS, HDF_TYPE, and TYPE?

What values are you giving HDF_SD_ADDDATA for START, COUNT, and STRIDE?

What do you get when you type

HELP,mydata

where 'mydata' represents the name of the field you're passing as the
data argument to HDF_SD_ADDDATA?
