Glad to hear it worked out for you GoingForward.
I have the 500mb Xtreme. I did get it reformatted, yet, I still have too much trouble getting it to mount. I don't use it.
Seagate Support says
"Unfortunately this drive is specifically supported for Windows operating systems only. We do not have any MAC drivers. You are correct we have Free Agent drives specifcally taylored for MACs and I would suggest these. However you may be able to get this drive to work by using your Disk utility to repartition and format the drive but we do not support this ourselves."
