Thanks for clarification. The access to the path works, except the access to the root dir of the volume. It appears as a regular file which apparently provides raw read access to the partition: $ ls -l '//?/GLOBALROOT/Device/HarddiskVolumeShadowCopy1' -rw-r--r-- 1 ... 0 Dec 1 2006 //?/.../HarddiskVolumeShadowCopy1 $ xxd '//?/GLOBALROOT/Device/HarddiskVolumeShadowCopy1' 0000000: eb52 904e 5446 5320 2020 2000 0208 0000 .R.NTFS ..... ... $ ls -l '//?/GLOBALROOT/Device/HarddiskVolumeShadowCopy1/' ls: cannot access //?/.../HarddiskVolumeShadowCopy1/: Not a directory $ ls -l '//?/GLOBALROOT/Device/HarddiskVolumeShadowCopy1/.' ls: cannot access //?/.../HarddiskVolumeShadowCopy1/.: Not a directory Files/Dirs below the root dir can be accessed: $ ls -l '//?/GLOBALROOT/Device/HarddiskVolumeShadowCopy1/boot.ini' -rwx------+ 1 ... 429 Jun 12 16:10 //?/.../...VolumeShadowCopy1/boot.ini $ ls -l '//?/GLOBALROOT/Device/HarddiskVolumeShadowCopy1/cygwin' drwx------+ 1 ... 0 Oct 31 16:14 bin drwx------+ 1 ... 0 Sep 12 2007 cygdrive -rwx------+ 1 ... 209 Jun 19 2006 cygwin.bat ...
