Using a 3TB External for Double Backup

I know the Readynas doesn't support larger than 2TB drives internally on the raid. And for some reason I totally spaced the 2TB limit on the system when I bought an external USB 3TB drive to keep an offsite backup of the Readynas.

I finally got around to hooking up the 3TB drive to the Readynas and formatted it the native fs probably ext3. However, it only sees 2TB. Had I have thought abot it first, this is what I would have expected. I am pretty sure this is a wash and it can't use the 3TB.

However, one thing that gave me hope is that the kernel reports it as 3000593 MB or roughly 2.86 terabytes. That is much higher than i would have expected on this sparc system.

SO, just in case there has been some development where I could use all 3 TB of the external drive to back my NAS up to, I thought I would check here before I returned it to the store.

Here goes. Is there any way to have the Readynas see all 3TB of the usb drive?

If not, would it be possible to use the 3TB external and have say a 1 TB partition + a 2TB partition and have both of them recognized and available to backup to? Thereby using all 3 TB of the drive, but in moremanageable sub 2TB chunks.
