There's no such thing as CORE in the cygwin distribution; you meant coreutils. > > I've discovered what I believe to be a problem with "dd" on several > different XP SP2 systems with Cygwin installed involving the usage of > Windows' \\.\PhysicalDrive nomenclature. That's your problem. Cygwin is a Linux emulation, and use of Window's \\.\ nomenclature is not guaranteed to work. Using the corresponding posix-y name is more likely to succeed, in which case the bug is not in dd but in your usage. > > That is, reading from \\.\PhysicalDrive1 with the below command works > flawlessly: > dd if=^\^\.^\PhysicalDrive1 of=tmp.img bs=16384 That's an unusual quoting style; it certainly doesn't work under bash. Are you by chance trying this under cmd.com? In which case, why are you bothering with quoting? cmd.com passes \ through without the need for quoting. At any rate, what you probably wanted something more like this (less typing, and no need for quoting, whether in cmd.com or bash): dd if=tmp.img of=/dev/sda bs=16K See http://cygwin.com/cygwin-ug-net/using-specialnames.html for more details. -- Eric Blake volunteer 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/
