I was able to get ntfsprogs to compile under cygwin 1.7 after some troubles=
hooting.  I tried to get ntfsclone to point to the //?/GLOBALROOT for a sha=
dow copy.  I know dd can do this.  ntfsclone doesn't appear to be aware of =
these devices and there are no /dev/sd?? associated with them either.  The =
shadow copy can easily be exposed as a drive under Windows using vshadow.  =
Ntfsclone is reporting this drive as being mounted rw when in fact it is ro=
 (shadow copies exposed as drives can only be read-only).  I don't see an o=
ption under mount in 1.7 to manually create a mount point read-only?=20=20

When I do mount the shadow copy it cannot access the global device.  mount =
reports the following:

D:OBALROOT/Device/HarddiskVolumeShadowCopy127 on /mnt/temp type unknown (bi=
nary,posix=3D0,user)

After entering the following command:

mount -o binary,posix=3D0,user,auto //?/GLOBALROOT/Device/HarddiskVolumeSha=
dowCopy126 /mnt/temp

I'm not sure why the result from the mount command shows it as "D:OB".  I'v=
e tried quoting the device in the command line to see if it was interpretin=
g the ? incorrectly.

I'm assuming that the open statement in ntfsclone needs to be modified?  An=
yone have suggestions on how to get ntfsclone to understand something like =
\\?\GLOBALROOT\Device\HarddiskVolumeShadowCopy126?  What change was made to=
 dd to allow it to see these shadow copies as devices?

------------------- 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.

Rob
