This is kind of mind-boggling. If you knew that you could access HarddiskVolumeShadowCopy using the POSIX path /proc/sys/Device/HarddiskVolumeShadowCopy why didn't you try to use the POSIX path as device name in a call to the POSIX tool dd, rather than translating it into a Win32 path? It's clearly marked as block device in the directory listing: $ ls -l /proc/sys/Device/HarddiskVolumeShadowCopy1 brwxrwx--x 1 Administrators SYSTEM 0, 250 May 28 15:31 HarddiskVolumeShadowCopy1 and here's what I get when running od -c on it as admin: $ od -c /proc/sys/Device/HarddiskVolumeShadowCopy1 | head -1 000 353 R 220 N T F S \0 002 \b \0 \0 Corinna -- Corinna Vinschen Please, send mails regarding Cygwin to Cygwin Maintainer cygwin AT cygwin DOT com Red Hat -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple
