I assume you have now a dual boot configuration with GRUB boot manager windows in first partion (C:) and OpenSolaris in second partition. to mount my C-Drive with windows ntfs filesystem I use:
mkdir /mnt/windows mount -F ntfs /dev/dsk/c4d0p1 /mnt/windows also check for packages FSWpart, FSWfsmisc -- This message posted from opensolaris.org
