Using large HDD on readynas DUO V1

Hi bogdahn

Duo V1 has no support for GPT Format. It was mentioned also by StephenB on this post.

Certain X86 devices from Legacy NAS were able to be converted from MBR to GPT format getting them to support larger capacity disks however for SPARC units like to Duo V1 it was not possible.

You may want to plan on upgrading your NAS Unit to newer models using OS6 if you really want to use larger capacity disks :)

Is it a a SATA controler limitation ?

Netgear never disclosed the exact reasons.  The Duo goes back to 2008, and the hardware architecture of v1 NAS generally was first released around 2005.  The first 3 TB disk drive came to market in 2010. 

The v1s have specialized hardware to handle RAID, and I believe that hardware is also in the Duo (even though with 2 bays it can only do RAID-0 and RAID-1).  So it could be hardware (sata controller and/or RAID hardware), or it could be firmware, or some combination of the two.
