hard drive failure

Is my hard drive toast? Massive Current Pending Sector count + sluggish performance of ReadyNAS.
Morning, I have a ReadyNAS Ultra 2 running RAIDiator 4.2.27 using RAID Level 1. As well as providing storage for a lot of media, It was also being used as a Time Machine backup from my macbook and I noticed that the time taken for a backup to complete greatly lengthened nearly two weeks ago. So checking the logs, I have the first appearance of this message: Detected increasing pending sector count[65535] on disk 2 [WDC WD30EZRX-00MMMB0, WD-WCAWZ1421563]. This often indicates an impending failure. Please be prepared to replace this disk to maintain data redundancy. on Oct.10 with further instances after, although not every day and with the number decreasing albeit by very little (latest log error message has the figure at 65515). Checking this thread on the NETGEAR forums and running SMART, the Reallocated Sector Count is zero. My questions are: since the HDD isn't even able to remap the sector, it's a goner isn't it? I have already ordered a replacement - is it best practice with a NAS to have two HDD that are exactly the same make if possible? The two 3TB HDDs currently in the ReadyNAS are WD Caviar Green (WD30EZRX), the replacement will be a 3TB WD Green (WD30EURS); I guess as long as both HDDs are of the same capacity, it doesn't matter. is the slow and sluggish performance of my ReadyNAS a result of the problems with disk 2 in my array as it continually attempts to re-write or remap the bad sectors without success? I've stopped using it as a TM backup as I was already using an external HDD for an additional disk to backup using TM to, as although it would eventually complete, it would take 2+ hours to complete. lastly, when I've got my replacement drive, is it simply a matter of swapping the HDD in the disk 2 bay and it ought to just start copying all the data across from disk 1? Thanks in advance for any replies.Solved
ReadyNAS NVX Drive failure and replacement options
I have an NVX with 4x 2TB Seagate drives, configured as a single volume using X-RAID2. It reports Online, X-RAID2, 4 disks, 37% of 5548 GB used. Earlier today I got " Thu Sep 1 00:01:42 MDT 2016 Disk failure detected. Following a power supply problem a few months ago I acquired a 2nd NVX to use as backup. I has 4x 1TB Seagate drives. It's so far unused. By Coincidence today amazon delivered 4x 2TB Seagate drives for the backup NVX and I was going to set-up rsync to backup one to the other. So, short term I can take one of the proposed backup drives and plug it into the primary and buy another 2TB drive. Alternatively, since I don't need the full 5TB capacity, it occurs to me I could ut a 1TB drive in the primary NVX; then build the backup NVX with 1x 1TB and 3x 2TB and be left with a spare 3x 1TB and 1x 2TB drive ready for future drive failure. Make sense or am I missing something important? Both NVX are already running the latest/last RAIDiator-x86 Version: 4.2.28Solved2.9KViews0likes2Comments
