Accessing Xubuntu from Ubuntu

[squareyes]

Hi all,
I have both Ubuntu 6.60 and Xubuntu on the same drive.
Is there any way I can access Xubuntu from Ubuntu?
Ubuntu on hda1,  Xubuntu on hda3. An icon shows on desktop for hda3, but 
can only
access "Lost+Found"

squareyes at here:~$ mount /media/hda3/
mount: according to mtab, /dev/hda3 is already mounted on /media/hda3
mount failed
so it's mounted OK

/etc/fstab
# /etc/fstab: static file system information.
#
# <file system> <mount point>   <type>  <options>       <dump>  <pass>
proc            /proc           proc    defaults        0       0
/dev/hda1       /               ext3    defaults,errors=remount-ro 0       1
/dev/hda3       /media/hda3     ext3    defaults        0       2
/dev/hda5       none            swap    sw              0       0
/dev/hdc        /media/cdrom0   udf,iso9660 user,noauto     0       0

Thanks in advance.
