I don't understand why this is not working.
Meanwhile you can use rgdal::writeGDAL
library(raster)
library(rgdal)
r <- raster(nrow=10, ncol=10)
s <- stack( sapply(1:2, function(i) setValues(r, rnorm(ncell(r), i, 3) )) )
s[1:6] <- NA
single <- s$layer.1
writeGDAL(as(single, "SpatialGridDataFrame"), fname = "idri.rst",
drivername = "RST")
GDALinfo("idri.rst")
