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 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!
