Are the drives fat32 or ntfs, you may have only read access if they are NTFS or get filesystem not supported by kernel...
As for mounting them automatically...first you need to make a mount point. Like this...
then you need to add a line like this into your /etc/fstab
/dev/hdb1 /mnt/wins vfat defaults 0 0
that would be for a fat32 filesystem(vfat) on the hdb1 partition, that you wanted to be mounted to /mnt/wins.
If it is an NTFS filesystem then you would add the same line but instead of vfat you would put ntfs on the line.
If you have more than one partition that you need to mount then just create another mount point such as /mnt/wins2 and add another line to your /etc/fstab with the correct partition(such as hdb2) and filesystem.
Now your system will automount these on boot so they are always available to you.
Hope this helps,
