On Win8, you must share the folder/partition (remember to set the appropriate read/write permissions).
On the Linux:
mount -t cifs //10.10.10.18/name_of_the_share /where/to/mount
from a root shell or preceded by 'sudo'.
To make this a permanent mount, add this to fstab:
//10.10.10.18/share_name /mount_point cifs rw,user,noauto 0 0
means to mount it in write mode, user
means a user can mount it and noauto
means it won't be mounted during arch boot (delete it if you're sure the share is always available, or you have to wait several seconds at boot for the timeout)
ending zero means to don't check at mount/boot
ADD: two more parameters are needed if the mounted share belongs to root, so you don't have permissions to write or read : uid
you can have this number simply by running 'id' in a shell
//10.10.10.18/share_name /mount_point cifs rw,user,noauto,uid=100,gid=200 0 0
means the mount user owner is 100 and the group owner is 200 (every user on linux have an unique uid and is a member of many gid - at least one)
