Well, I didn't want to get into specifics because this isn't exactly 
educational.  I'm going to be using this drive as storage for MythTV 
recordings.  So, mostly huge files bigger than 5Gigs each.

BTW - Here's what I'm talking about.  This doesn't look right to me.  
First I fdisk I typed n for new partition, I selected primary, I 
numbered it 1, then I took the defaults for first and end block.  Then I 
hit "w" to write it to the partition table.  Then I did the following.  
That looks like an awfully small partition to me.  What did I do wrong?
