Yeah its quite easy do but your Windows drive needs to be FAT. You may be able to get it working with NTFS too but its easy for data to be corrupted it seems.
So assuming its fat, simply click the Star > System Tools > Hardware Browser.
Click Hard Drives and you will see something like Drive /dev/hda. Note this down as you will need it.
Open a terminal and type pico /etc/fstab
You will see the format the syntax is in, so just add
/dev/hda /mnt/data vfat defaults 0 0
and just make sure its under the text above it.
Now press ctrl & O at the same time to save. Then ctrl & x to exit. Now reboot.
Obviously yours may not say /dev/hda as your Hardware Browser may have told you something different. My /etc/fstab file looks like this.
LABEL=/ / ext3 defaults 1 1
none /dev/pts devpts gid=5,mode=620 0 0
none /proc proc defaults 0 0
none /dev/shm tmpfs defaults 0 0
/dev/hda3 swap swap defaults 0 0
/dev/cdrom /mnt/cdrom udf,iso9660 noauto,owner,kudzu,ro 0 0
/dev/fd0 /mnt/floppy auto noauto,owner,kudzu 0 0
/dev/hdb5 /mnt/data vfat defaults 0 0
Now when you reboot it will be auto mounted for you. [/code]
