ExifTool not creating thumbnails

This is my second attempt at creating this post - god only knows what happened to the first one.
I am trying to create jpeg thumbnails from my Sony raw files (ARWs).  Despite the fact that I think that I have copied an example from ETs documentation, and despite the fact that I did this successfully, once, when I tried it a couple of months ago, I cannot get it to work now.

I open a command window in the directory containing some .ARW files, and the enter the following:

Code:

"...pgm-dir...\exiftool.exe" -b -JpgFromRaw -w _tn.jpg -ext ARW -r .

This has no effect - literally.  ET just does nothing, except sulk.  It appears to execute, but produces nothing, not even an error message.  Can anyone tell me what, probably obvious, error I am making?

When this happens, it is because the images don't contain
the information you specified.  Most of my ARW samples
contain a PreviewImage, and some of them also contain
an OtherImage (which is usually smaller than the PreviewImage),
but I don't see any with a JpgFromRaw.

Did this behaviour change?  I did a quick check with older
versions of exiftool but I can't find a version that ever extracted
a JpgFromRaw from ARW.  But I did notice the OtherImage a while
ago and wondered if I should be calling it JpgFromRaw instead.
I will look into this, and may change this for the next release.
