Fedora Core 1 works so well for me , that I've removed windows entirely!
Grant Rickfords book on FC1 taught me how to get the use out of a non-windows OS that I was looking for.
I installed FC1 on a single hard drive & performed all the updates listed in his book. It is now the centerpiece of my home entertainment center.
How do I get FC1 to recognize and utilize a 2nd hard drive that has been installed & formatted in ext3?
I am unable to find any tools in the GUI that allow me to partition & format another drive like the tools in windows.
I used a RH install cd to format the second disk with an ext3 / {root} partition. It is now identified in the OS as ext3 / , but I'm unable to use it.
Perhaps someone can enlighten me as to just what i did wrong. I still have much to learn!

I'm still really newb but this might help:

# mount -t ext3 /dev/hdb1 /mnt/hdb
.................................^device ........^mount directory

This should at least get you in the right direction and you can use;

# man mount
or
# mount --help

to help figure out how to mount it properly.

Hope this helps!
