[X4U] firewire drives

[spoonbender]

Hi all,
I have an LaCie 160 GB external firewire drive, with both the 800 and 
400 and USB 2.0 connections. I am running a Powermac G4 quicksilver 
(2002) 1.2 gig processor and 1 gig of ram, running mac os x 10.3.7. I 
used CarbonCopyCloner to clone my system and made sure the box that 
said 'make bootable' was checked. Funny thing is when I open the 
firewire drive icon to see whats on the drive I only see the folders. 
No dev or boot or etc files. Im rather new with the use of firewire 
drives so Im not sure if Ive done something wrong or no. Also is it 
proper to leave the firewire drive on or just turn it on when you need 
it ?
Thanx,
spoonbender...
