OK, time to ask the dumb question.
Since you formatted it with Windows, did you use Ntfs-Config to enable read write support in Ultimate Edition?
Since some software is picky about which Sata slot you use for a HD, check the Bios to make sure your drives are plugged into Slot 1 & 3
If all else fails, open up Windows again and this time fire up Partition Magic to format it.
I want to say PM allows you to format Ext3, but I can't remember for sure.
