I tested with the live cd. It finds all the partitions that I have including windows and files...
But when I installed vector linux, it is showing only linux partitions. Why?
I have to browse all the fat32 partitions in vector. How? Pls help...

This is cheating...
Run the live CD. When it has completed booting, open a terminal, change directory to /etc and copy fstab to one of your hard drive partitions. Then restart the installed version, backup /etc/fstab, copy the saved version into /etc, create the necessary directories and you're done...
