I had not come across --fatfilename.  Thanks for drawing it to my attention. 
It says it is always applied on Windows.  That explains why I have never had 
an invalid file name generated by get_iplayer even if the BBC puts in a 
colon (which it does not do as often as the other UK broadcasters).  It 
probably makes sense for it to be the general default, or better to use a 
lowest common denominator character set across all operating systems.

As for the problem which started this thread, very slow HLSHD downloads in 
Windows 10 to an external 2TByte USB3 drive over a USB2 connection, I have 
now eliminated a faulty drive as the cause.  The replacement is slightly 
faster at 2.5Mbit/s instead of 2.2Mbit/s but it is still 1/30 of the speed 
of downloading to an internal drive.  The slow down does not affect a laptop 
with an AMD chipset and Windows 10 Pro.  It does not affect a 1TByte drive 
from the same family.  It does affect two machines with Intel chipsets 
running Windows 10 Home.  One is a Dell Vostro 400 and the other is a 
Toshiba Satellite A100.  There is a difference between them.  On the Vostro 
the large file writing speed to the external drive without write caching is 
10MByte/s.  On the Satellite it is 25MByte/s, which is much closer to the 
30MByte/s large file writing speed to the 1TByte drive.  I guess it must be 
the USB driver, but they all claim to use the same 10.0.10586.0 driver 
version dating from 21/06/2006.
