So, I installed NT on one of the FAT partitions, formated the whole new drive on NTFS and reinstalled NT on the new partition. I still don't understand why NT didn't want to create the 6.4GB partition the first time... It didn't complain about the size when the partition was already there.

Using just NT, AFAIK, no. The trick I use is to set up a tiny (well, maybe 20-30MB) primary partition with DOS on it to serve as the home for the boot loader, and then set up an extended partition as big as I need and allocate a logical drive and format it as NTFS using Partition Magic (shameless endorsement - if you set up many systems, you desperately need a copy of Partition Magic! PowerQuest has a great product there, with a bunch of nice utilities, including a boot manager that makes dual boot setups much easier when you started with just NT and then want to add something later. And their DriveCopy utility is great, too, when switching to a new, larger drive - it'll take all the partitions from your old drive, resize them where aprropriate (works with FAT and NTFS for this, and it understands the system partition/boot partition issues) and migrate them to the new drive, adjusting allocation and drive layout as needed. I'm a big fan.)
