Here's how I do it in a little batch file that I put on
my USB pen drive:
It's in the attached .TXT file - you'll need to rename
it to .BAT
Note that this batch file will OVERWRITE your fstab so
please review it before installing and using it on your
system.
Basically, it lets me carry Cygwin on a USB stick and
it does not care what drive letter it's attached as.
Note also that USB sticks are slowwww, so it's just for
emergencies :-)
