Linux RAID 1 question

Currently I have SUSE 10.0 installed on a no frills 80 gig HD, sitting by itself and acting as my router/temp space. My question is, I have a matching 80 gig HD that I want to place into a RAID 1 array with the existing hard disk that has SUSE installed without losing any existing data. Is this even possible under Linux software RAID?

I have ordered a 3ware 7506 8 port IDE card for the rest of the hard disks that I plan in adding to the file server. If linux software raid can't mirror the drives without losing the data would anyone who owns a 3ware card know if it's possible with their BIOS/Software? (I read the online manuals on their site but there was no info about losing data) or am I doomed to start over? Thanks for the help in advance.

 
I THINK so...you create the array, with only one disk (it's instantly in a "degraded" state) add the second drive to the array and then it rebuilds, or you may have to tell it to rebuild.

you could also copy dd it to the second drive before doing this, to ensure you don't lose anything.
