The issue appears to be with ntfsclone in that it must point to something i= n /proc/partitions. It will not work with any /cygdrive/X (used dosdev.c f= rom Corinna and typical vshadow to expose as a drive with no luck). I foun= d this out by commenting out the read-only check and rebuilding ntfsclone/n= tfsinfo. The code apparently uses a win32_io.c file when building on cygwi= n. This file creates its own device mappings (e.g. /dev/hda1 instead of us= ing the existing /dev/sda1). I guess there would be a way to modify it to = use cygwin devices but I don't know how. If shadow copies could be presented as block devices to this library then i= t would open up a lot of possibilities for creating block-level clones of p= artitions without having to boot to a live CD. I guess it is dd piped thro= ugh gzip for now. It sure is a waste when you only have 50GB on a 500GB dr= ive since dd processes the entire drive. Does anyone have anything else to add? I'm guessing not... Rob =20 ------------------- original note Does anyone know of an ntfsclone package that works under 1.7? I tried com= piling 2.0 from sourceforge. I didn't get any errors from ./configure, mak= e, or make install but the executable doesn't return anything when I run it= . ntfsclone --help doesn't return anything either. I've been using dd with volume shadow copies to capture partitions (very co= ol direct reference of //?/GLOBALROOT devices!). I'd prefer to use ntfsclo= ne for speed.
