To mount a partition automatically you use the "auto" option in the filesystem table.
You need to post the output of:

fdisk -l

cat /etc/fstab

then someone can answer your question completely.

Example

/dev/hda1 ntfs /mount/winxp auto,users,exec,umask=022 0 0

would mount the first hard drive ntfs partition at mount point /media/winxp with read permissions
for any user who is a member of the group users
