    I'm running IDL Version 7.0 (linux x86 m32). I'm creating a HDF files and load some data in it. When the files get bigger than about 2 GB I am not able to close the file. Here is a pseudo code showing what I do. EFF_GRID = HDF_SD_Start("grid.hdf",/Create,/RDWR) for i = 0,N do begin             data = somedatatosave_i              ID_data = HDF_SD_Create(EFF_GRID,NAME[i] $              ,[bignumber])              HDF_SD_AddData,ID_data,data              HDF_SD_EndAccess,ID_data endfor ; When grid.hdf is bigger than 2GB ;"HDF_SD_End,EFF_GRID" is not working HDF_SD_End,EFF_GRID   Is there any fix to that problem!

    HDF4 has a file size limit of 2GB. IDL also supports HDF5, which allows file sizes larger than 2 GB and would be a good option to try instead. Bill Okubo - IDL Product Manager
