What is an "NTFS raw device" for you? > I think I will fill a bug report for the dd command under Cygwin. Could > you point me where to do it? There's no point in that. I removed the buffering in writing to raw devices last year because the buffering created more problems than it helped when it came to writing multiple-volume archives to, e.g, floppy. Windows calls OTOH only support writes to raw devices in module blocksize chunks. I don't think that's too hard a restriction.
