Hardware Errors on Mirrored 750GB Seagate Disk on NV+(4.1.6)
Hi All,
I'm running 2 x 750 GB Seagate drives (as originally supplied on the NV+) one of which is exhibiting drive errors.
The NV+ reports current config as under:
Online, X-RAID, 2 disks, 71% of 688 GB used
Firmware: RAIDiator 4.1.6 [1.00a043]
This started when we moved PST files over to the NV+ to have clients access them online.
However, when indexing these PST files (with Lookout), then the NV+ would lock up and now the log is reporting the HD errors. (Only one disk reporting)
The only way to restart the machine was a forced shutdown, so the logs reflect this (Have not opened that Outlook client, due to the fact that it locks up the NV+, which is why there are no problems since the 17 Feb note in the log):
Fri Feb 17 04:00:07 IST 2012 ATA error count has increased in the last day. Disk 2: Previous count: 1656 Current count: 1677 Growing SMART errors indicate a disk that may fail soon. If the errors continue to increase, you should be prepared to replace the disk.
Thu Feb 16 12:44:03 IST 2012 RAID sync finished on volume C. The volume is now fully redundant.

Wed Feb 15 21:14:22 IST 2012 Improper shutdown detected. To ensure data integrity, a filesystem check should be performed by rebooting the NAS through Frontview with the volume scan option enabled.

Wed Feb 15 16:07:37 IST 2012 Improper shutdown detected. To ensure data integrity, a filesystem check should be performed by rebooting the NAS through Frontview with the volume scan option enabled.
Wed Feb 15 14:05:22 IST 2012 A SATA reset has been performed on one or more of your disks that may have affected the RAID parity integrity. It is recommended that you perform a RAID volume resync from the RAID Settings tab ( accessible in the Volumes page => Volume tab in FrontView ). The resync process will run in the background, and you can continue to use the ReadyNAS in the meantime.
Wed Feb 15 14:05:07 IST 2012 Access to the disk on channel (??) is producing I/O errors. Although the array is still redundant, please replace this drive as soon as possible, as it is likely to fail soon.
If we are currently on X-RAID, then I could just slip in another disk and it should become redundant, allowing me to remove the one bad disk - or do I need to add 2 more disks?
However, I just purchased 2 Western Digital 2 GB disks, which this firmware (4.1.6) might not be able to handle, right?
I know I should do a backup before updating firmware, so need to know whether the NV+ would recognize the 2 TB Western Digital Caviar Blacks (WD2002FAEX) as they are?
Thanks for any feedback on this!

So it's just the 4k sector partition alignment that needs to be considered.
Sorry for being dense - but doesn't this mean that the block size is 16k, rather than 4k or 512 bytes? - mdgm-ntgrNETGEAR Employee RetiredThe block size of the volume is a completely different issue to the partition alignment of the partitions on your drives.

But is there any benefit to 4k sector partition alignment - other than (I think) the greater amount of data that can be written to the disk/s? (Thus, greater efficiency?) - mdgm-ntgrNETGEAR Employee RetiredIf you purchase disks that are 4k sector disks you will have poor write performance if you don't have 4k sector partition alignment.

Is there any benefit to using the 4k sector disks? - StephenBGuru - Experienced User
They provide > 2TB capacitiesSuperFlyBoy wrote: Is there any benefit to using the 4k sector disks? - mdgm-ntgrNETGEAR Employee RetiredThe NV+ (v1) can only use drives up to 2TB in capacity. With the transition to drives larger than 2TB in capacity lots of 2TB drives have been released with 4k sectors in preparation for the 3TB and 4TB drives that have since been released. Now the question you have to ask is even if your disks are not 4k sector disks and the 2TB disks you purchase aren't 4k sector disks if you need replacements in a few years time will there be non-4k sector disks available?

Right, so we would have to transition our hardware (NAS) to another more modern one, I would think, right?
