4k sector support.

No, No, No. The block size has nothing to do with the disk sector. Originally the Sparc based ReadyNAS had 4K BLOCK size under RAIDiator versions prior to 4.x. But that limited the max size of the volume. As larger and larger drives started coming to the market, they increased the BLOCK size in RAIDiator to 16K. Any factory default after version 4.0 has the 16K BLOCK size. This has nothing to do with SECTOR size. I believe that the 16K block size is unique to the sparc based ReadyNAS units as well. As hard drives started getting larger and larger, they also started running into limitations so beginning a little over a year ago, they started using the 4K SECTOR size rather than the traditional 512K SECTOR size that had been used since the first hard drive was marketed. BLOCK size - function of OS (RAIDiator) SECTOR size - function of HDD structure.

Sorry for confusing the issue - clearly I misunderstood the post here: viewtopic.php?f=66&t=61193&p=344748#p344748

Anyway, checking sector alignment on DUO and NV+ V1 is found here: http://www.rnasguide.com/2011/06/22/why ... -readynas/

You need to check the starting sector of each partition, and see if is divisible by 8. In your partition.log that does not seem to be the case.
