Try using the patched version of b20.1, supporting raw access to partitions, hard drives and tapes on ftp://ftp.franken.de/pub/win32/develop/gnuwin32/cygwin/porters/Vinschen_Corinna/B20 named cv_cygwin1.dll.README cv_cygwin1.dll.tar.gz I have noticed an error in it, yesterday, which prevent usage of raw devices as stdin, but usage as parameter as in dd if=/dev/st0 ... is possible. The error will be corrected in one of the next winsup-snapshots. Note, that the blocking factor is a _very_ important setting, because windows sets default blocking of 512 bytes on raw devices. If your SUN writes with 5120 bytes blocking, you'll have to set the correct blocking factor, too, if your tape drive has variable blocking factors. Try usage of the following commands from the forementioned web page: mt: mt-1.8.README mt-1.8.tar.gz (very useful! Setting of blocking factor as with linux mt) cpio: cpio-2.4.2.README cpio-2.4.2.tar.gz tar: tar-1.12.tape_cygwin1.README tar-1.12.tape_cygwin1.tar.gz The dd from cygwin package is ok.
