Using SCSI card in Single user mode

I'm trying to boot my G5 into single user mode and then mount some external hard drives via an Adaptec 29160 SCSI card. I have some *nix experience and have done it previously with modprobe, but Darwin is a new beast for me. From other posts i found info about 'sudo kextstat' and found that com.adaptec.driver.7892 and some other files have been autodetected/loaded at startup, but that really hasn't helped.
1. Are these all the files needing to be loaded

2. How can i determine what device my hard drives are known as. (i.e. for me to 'mount /dev/????? /Volume/harddrive1' )

FYI, for those wondering why i want to do this. I want to copy off data or do dd imageing from one drive to another and want to make sure that the source drive is mounted in a read-only mode. -- Any other alternatives.

Thanks
 
Why not boot normally, do a Command-I on the drive, and make it Read Only with Ownership and Permissions?
 
Ooops! Forgot to mention that this is a new G5 and i am therefore a complete newb to Macs.

So uh i got the Command-I part, but how do i go about changing the drive to read only.
 
Command-I opens the Info Window. You'll see at the bottom, Ownership and Permissions. Change to read only.
 
I'm there but don't see how it can be changed. The Names and Extensions line gives me a place to change the title of a drive, but there is no option that i can see for changing the permissions from a Read and Write to a Read Only
 
This is what the Info window should look like;

I wish it looked like that, but it doesn't. It just says "you can read and write"

No box or arrows for choice.
No Details line.
No Ignore ownership line.
 
Do a Command-I on your main hard drive icon and see if it's the same.
if it is, enable Root and try

Open NetInfo Manager in your Utility folder. Go to the Security Menu at the top and enable Root. then do a Command-I.

You might not want to leave root enabled, you can do anything to the machine that way if you're not careful.
 
Well, no luck. Command-I on my main drive at least gets me a box (greyed out) around the 'read and write', but nothing changed for the other drive.

i changed the Security/enable Root option, but still no change to Info window.

Wife's calling cause i'm still at work. She's hungry...me too. Will try some more later.

Thanks
 
It sounds like you are not logged in as Admin/Owner. Check the Users panel in System Preferences (light switch on your dock) - change your username to admin owner. You will need to type in your password.

Now you should be able to change permissions. If you still have trouble>go to the Utilities folder>Disk Utility and use Repair Permissions to verify and repair your drive. You do not need to boot from the OS CD to do this.
