File Browser shows unmounted partitions

Hi,

File Browser in Ubuntu 7.04 is showing unmounted partitions.

My setup details:
i386 - Two hard drives - /sda1 and /sdb1
Windows on /sda1 - there are other partitions as well on this drive
Ubuntu on /sdb1 - mount information as follows:

rks@rks-home:~$ mount
/dev/sdb1 on / type ext3 (rw,errors=remount-ro)
proc on /proc type proc (rw,noexec,nosuid,nodev)
/sys on /sys type sysfs (rw,noexec,nosuid,nodev)
varrun on /var/run type tmpfs (rw,noexec,nosuid,nodev,mode=0755)
varlock on /var/lock type tmpfs (rw,noexec,nosuid,nodev,mode=1777)
procbususb on /proc/bus/usb type usbfs (rw)
udev on /dev type tmpfs (rw,mode=0755)
devshm on /dev/shm type tmpfs (rw)
devpts on /dev/pts type devpts (rw,gid=5,mode=620)
lrm on /lib/modules/2.6.20-15-generic/volatile type tmpfs (rw)
/dev/sdb3 on /media/Store type vfat (rw)
binfmt_misc on /proc/sys/fs/binfmt_misc type binfmt_misc (rw)
rks@rks-home:~$

As u can see, none of the partitions on windows drive are present in the mounted lists.
 /etc/fstab has these entries:
proc /proc proc defaults 0 0
/dev/sdb1 / ext3 defaults,errors=remount-ro 0 1
/dev/sdb2 none swap sw 0 0
/dev/sdb3 /media/Store vfat defaults 0 0
As can be seen, no entries related to /sda1 in /etc/fstab too. And there's no entry related to the CD Drive as well.

When I open File Browser however, I see the following drives:
CD-RW/DVD-ROM Drive
52.2 GB Volume
54.0 GB Volume
My Store
Work1
FileSystem.

The attachments here are screenshots of the FileBrowser

Note: The Tree View seems to be ok, but the places view and the File upload dialog show the drives mentioned above.

As can be seen, none of these, except FileSystem are entries in /etc/fstab. They are all Windows Partitions on /sda1. How are they getting loaded??

Is there any other configuration file that i need to modify apart from /etc/fstab??

Please let me know.

Regards,
