If your hard drives are too large to be managed by your controller (in my case 1.5TB HDD with an adaptec SATA RAID SA2420 card, with 1GB per HDD max.) you can resize them using using the Samsung EsTool available here. All details on the same page.
To resize your disk use the SET MAX ADDRESS feature. After resizing, you will be able to use them with size limited controllers (of course you can restore the initial size if needed).
