Perhaps with the latest versions you may pick up a bug fix along the way that helps solve your problem.

Maybe that is your problem? Also, according to `stat /dev/sda', the IO block size of an NTFS raw device is 1024, so even bs=512 may be equally dangerous. > PS: If I do only: > dd if=//./physicaldrive0 > --> dd is wrinting things on the command line. > That's to be expected. The of= flag is necessary to tell dd to put the output in the named (device) file, rather than on stdout. -- Eric Blake cygwin coreutils maintainer -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
