Hi Martin,
Hi Antonio,

There is at least a cygwin port of ddrescue. Just search for "ddrescue
cygwin".
yes, but I prefer a native Windows build because I need it on many different
boxes and only occasionally on one particular box. And all of the boxes don't
have cygwin installed.
The Cygwin version of ddrescue does not require a Cygwin install. It
requires only cygwin1.dll is in same directory or in the PATH. I have
successfully run this ddrescue.exe also from a UBCD4Win Live CD without
a Cygwin install.
I've done a quick build of a native Windows ddrescue.exe with MinGW g++.
Required only few hacks (attached).
to build on MSYS:
$ ./configure
$ make
to build on Cygwin:
$ ./configure CXX=g++-3 CPPFLAGS=-mno-cygwin LDFLAGS=-mno-cygwin
$ make
(Or: cross-compile it on Linux :-)
But this version does not work with raw devices (e.g.
'\\.\PhysicalDrive1') because lseek(., 0, SEEK_END) fails. The
lseeki64() from MSVCRT.dll apparently cannot be used to determine the
size of a raw device.
Did you actually try your code with a raw disk or CD/DVD device? Which
MSVC version did you use?

Christian
