Re: associating device names with cygdrive directories

["Charles D. Russell" <worwor at bellsouth dot net>]

 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.
