Problem copying disc image to firewire drive

[russ1302]

I'm about to copy the osx86 image to a firewire drive via my Mac, as described on

http://osx86.theplaceforitall.com/howto/, but I'm stuck. I'm not sure how to designate the firewire drive (named osx86) in the terminal. I don't want to send it to the wrong drive. Here is the portion of the instructions that I'm stuck on.

 

"3. Go into Terminal and type df. Hit "ENTER." You should now see something like this in the Terminal window:

df Filesystem 512-blocks Used Avail Capacity Mounted on

/dev/disk0s2 147902984 71824768 75566216 49% /

devfs 185 185 0 100% /dev

fdesc 2 2 0 100% /dev

1024 1024 0 100% /.vol

automount -nsl [243] 0 0 0 100% /Network

automount -fstab [297] 0 0 0 100% /automount/Servers

automount -static [297] 0 0 0 100% /automount/static

/dev/disk2s2 204720 183224 21496 89% /Volumes/SomeVirtuaDisk

/dev/disk3s3 77903136 51976704 25926432 67% /Volumes/OSX86

 

My target disk is the "OSX86," so it is /dev/disk3s3, but don't use the "s3" bit because it is about partitions. I will call my disk /dev/disk3. Find out the /dev/disk of the disk you want to install OSX86 on, all info on this hard drive will be deleted. Just make sure you don't target the wrong disk, if you do you might wipe all data on your hard drives."

 

How do I find the dev/disk information I Need

 

Thanks
