Harddrives failing?

Hello,

I am doing the IT for our office and we have a ReadyNas Duo with two 500gb harddrives installed.

Recently the NAS has been behaving badly. It becomes inaccessible on the network. This started this week. Rebooting the NAS has cured the problem once. Unsure if it solved it on another occasion as I was out of the office.

Data:

Disk 2 has had growing SMART errors by 1 every two weeks and so up to 30 as it is now. However it is disk 1 that has the reading soft errors and the hardware ecc recovered. I do not know what this means.

Is one of my disks going and if so which one? Could it be another reason why it is dropping of the network? Our office is depended on the NAS and I will have to resolve it quickly.

Many thanks,

Kris

    I think the disk with reallocated sectors has a problem but you should check both disks as the problem disk could be either of them.

    I would suggest you power down, remove all disks (label order), connect them to a SATA port on your PC and check them using vendor tools

    Welcome to the forum!
  • Thanks,

    Volume Scan Found no errors. But I guess the vendor tools are more comprehensive than the Scan.

    Will try to get them into a PC for futher testing.
