Is there an easy way to find the association of a given /dev/sd? with
the corresponding /cygdrive/?. Is there a good way to verify the
association before writing to the device with dd?

Thanks. That is the mapping I was looking for.

How would you handle the case where you have more than a single mount
which looks like that? e.g.)
/dev/sda1 on /live/image1 type vfat
(rw,noatime,fmask=0022,dmask=0022,allow_utime=177777,codepage=cp437,iocharset=utf8)
/dev/sdb1 on /live/image2 type vfat
(rw,noatime,fmask=0022,dmask=0022,allow_utime=177777,codepage=cp437,iocharset=utf8)

If I know that /dev/sda1 maps to /live/image1, then I can use df and ls
on /live/image1
to identify the device - easier than using dd |strings on /dev/sda1.
I'm concerned
with distinguishing among USB storage devices.

/dev/sda3 \\.\D:
/dev/sda1 is not available under a drive letter, so that's fine.

Nice, but evidently requires your patches, not working on my installation.

I would use gmane to enable this, but I'm on dial-up at the end of a
miserable rural telephone line in Maine, where even DNS lookup usually
takes several tries, and servers that are not patient enough for lots of
retries simply won't work.

Thanks everyone. I was successful in creating a bootable USB flash
drive using Cygwin to dd from debian-live.img.
It was so slow, though, that I will forget about using Cygwin to clone a
hard drive.
