writing large 3D data file fails [message #68263]

One more question:

I have a fltarr of 4008x4008x865 voxels that I'm trying to write to a
file using

GET_LUN, lun
OPENW, lun, '/nfs/blahblah.dat'
WRITEU, lun, volume
CLOSE, lun
FREE_LUN, lun

this normally works like a charm for writing a simple binary data
file, but for this large dataset, I can't get it to work? The file
that get's written is way too small (about 3.5 GB - if I write it as a
netDCF it is ¨21 GB, which is more like the right size)

Any ideas what goes wrong here?
Thanks,
Dorthe
