file system questions

[Kevin Kempter]

Hi List;

I have a laptop running Fedora 7. I can remove the CD drive and insert a tray 
which holds an SATA drive in its place, it's a nice feature since it gives me 
a second drive connected the same way the CD drive was (i.e. not 
USB/firewire) so it's fast.

I have a spare drive from when I was running FC5, It has multiple file systems 
on it (/boot, /home, /var, etc).

I want to re-vamp it so I end up with a single file system on it which 
encompasses the full drive. I suspect I need to use rmfs to remove each file 
system and then mkfs to create a single fs on the drive but I'm quite 
unfamiliar with the fs commands.

Is this the best approach? any gotcha's, etc? Can I do this with  the second 
drive un-mounted? 

Anyone have any helpful examples of usage for rmfs and mkfs ?

Thanks in advance...
