A probably unnecessary warning/disclaimer here, BTW:

Don't do this if you're going to blame me for telling you to do it!

For any of you readers out there who aren't familiar with dd or your Mac's 
hardware:

THIS CAN BE VERY DANGEROUS!

what this is doing is copying raw data onto a raw hard disk.

If you have more than one hard disk before you plug in the CF, the "disk1" 
part will be different. You have to find out what disk number the CF is 
appearing as (you can do "ls /dev/disk*" before and after plugging the CF 
reader in).

If you mistype and say "disk0" instead of "disk1" you will COMPLETELY TRASH 
your MAIN HARD DISK'S partition table and file systems.

So be really sure you know what you're doing before typing!

(or do what I did: use someone else's Mac!)
