You will find a 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
The newer snapshots of winsup (since winsup-990130, I think) contain this patch,
too. Nevertheless, you should download the forementioned README for a short
description of the features.
Regards,
Corinna
