yes, this is sluggish . I just converted a 18002x22000 byte 3-band
dataset in 28 minutes.

More information, probably it does not fail but it is extremely slow.
After 15 minutes I am now at this stage

*Aihe:* Gdal_translate into HDF4 fails
Hi,
There is a question about HDF4 in
https://gis.stackexchange.com/questions/424204/convert-geotiff-to-hdf-using-gdal.
I tried the same with GDAL 3.4.0. With a single band image conversion
from GeoTIFF into HDF4Image succeeds but with a 3 band image not. I am
not sure if it is even supposed to work and the driver test in
https://github.com/OSGeo/gdal/blob/master/autotest/gcore/hdf4_write.py
is rather simplistic.
So, should “gdal_translate -of HDF4Image 3band.tif out3band.h4” work?
