Try using the patched version of b20.1, supporting raw access to partitions,
hard drives and tapes on
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-1.8.tar.gz (very useful! Setting of blocking factor as with linux mt)
The dd from cygwin package is ok.
Hope, this helps,
