ReadyNAS Duo: OK to use smaller height Seagate Desktop 1TB Model# ST310005N1?

OK, wanted to circle back around and provide an update.  Long story short, thank God that I decided to replace the drive and not wait!  While I was contemplating whether I should keep the failed drive in there until I could get a new fully compatible one, or pull it out to limit the risk of additional corruption on the good drive - the bad drive was actually completely failing and the NAS was going to force itself to shut down in 30 minutes.  I found this out after checking the logs once the sync finished - successfully!  I thought it might be helpful to post the log files so others could see the cadence of events and what might happen if they are in a similar situation.  Remember, if you have a drive with very high reallocated sector counts, you might NOT want to perform a re-sync as is recommended - safer option would be perhaps to NOT resync and get a replacement drive in there as soon as you can.  May not be like this for others, but in my experience the recommended Seagate Barracuda drives are horrible with this NAS; I have replaced FIVE of them already and Seagate says it's a NAS issues and NetGear says it's a hard drive issue.  I'm hoping some of the newer hard drives are more reliable than the much older Barracuda's recommended.  I love the fact that these new Desktop drives at least according to the NAS monitors are actually running 5 degrees cooler than the older Barracudas. 

Special thanks to MDGM for responding and guidance, really appreciate it.  I'm back in action and hope this might help someone else down the line!

The disk on channel 2 has failed. The NAS will automatically shutdown in 30 minutes to prevent possible data loss resulting from additional failed drives.

Disk fail event occurred on SATA channel 2. If the failed disk is used in a RAID level 1, 5, or X-RAID volume, please note that volume is now unprotected, and an additional disk failure may render that volume dead.

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.

Reallocated sector count has increased in the last day. Disk 2: Previous count: 10144 Current count: 25307 Growing SMART errors indicate a disk that may fail soon. If the errors continue to increase, you should be prepared to replace the disk.
