This question isn't strictly Cygwin, but I hope it's OK to ask it in the 
context of Cygwin on a portable device eg a CD or a usb mobile drive or 
memory stick: the bash command

	if [ -w /h ] ; then echo +W ;  else echo -W ; fi

tests a device located at /h (or /cygdrive/h) for write-ability: eg a 
USB memory stick will echo +W and a CD will echo -W. If the stick is 
locked, however, you still get +W. Does anybody know whether bash has 
the capability to distinguish a locked stick from an unlocked stick, 
(through "if [ ..", or by other means) please?
Even better, if it could be used to distinguish between write-enabled 
and write-protected folders/ files.
Thank you.
Fergus
