Title: How do you tell if the HDD has failed
Post by: Buaya on November 25, 2013, 07:40:10 PM
I am trying to understand the following

Currently under Web UI

ShareCenter->Management->System Status->Hard Drive Info

One of the disk is shown with a cross mark; i.e unhealthy.

My questions are
a) What does the "Unheathy" status mean? What actions are needed from my side?
b) After powerdown & startup of the enclosure, the HDD status changed from "Unheathy" to "Heathy"? Does this mean that there is no issue with the HDD?
b) Is there anyway to tell the HDD has failed from the enclosure front LED panel?

Would appreciate the clarification from the community.

Thanks

Log into the web UI and navigate to Management > Disk Management > S.M.A.R.T. Test. The S.M.A.R.T. Test will perform a HDD diagnostic and let you know if the ShareCenter finds anything wrong.

You may also want to go to the HDD manufacturer site (e.g. Seagate, WD, etc.) and download/install the HDD test tools on your PC. Since these tools are designed for specific make/model HDDs, they may provide a better indicator as to whether your HDDs are healthy.

If you have a HDD that is failing and the HDD is still under warranty, you can request a replacement from the manufacturer.

Regarding your specific questions, I don't have all the answers, but here's what I can offer:

(a) Unhealthy means that the DNS-345 has determined there is something wrong with the HDD. I can't say whether "Unhealthy" refers to the HDD's physical health (e.g. mechanical) or logical health (e.g. data corruption, filesystem issue). The S.M.A.R.T. test will look at the physical health of the HDD.
(b) I'm not sure what circumstances would cause erroneous results (run the tests I describe above)
(c) I don't know if the front LED will provide any indicator messages regarding HDD issues

JavaLawyer,

Thanks for your response. I will look into the tools that you mentioned. Will come back with questions if I am stuck.
