resinch a dieing disk or add new disk & resinch?

OK, run SeaTools on an oldish PC with a floppy drive (could not save the SeaTools logs, which could not be written to CD).
All SeaTools tests were passed (again), including the ERASE test. No particular infos about finding and relocating/moving bad/slow sectors but I do not know if this would have been reported.

My general feeling is that the disk was fine all along, and ReadyNAS threw a wobble /false alarm. I just checked the firmware, it is on RAIDiator 5.3.9, and I have downloaded 5.3.10 which I will install shortly, but there seem to be no relevant changes / bug fixes, only enhancements to cater for newer systems.

We played safe, but "better safe than sorry" - old adagios have a reason to exist !
Thanks !

Here is the SeaTools Logs, I was experimenting as I did not know if it wrote a new log or it added to it everytime.

FYI, Acronis Disk Monitor is a freeware tool that will show you the SMART stats. There are others. Of course the NAS will also show them to you.

Generally the vendor diags have a fairly high threshold set - minimizing their returns. I use lower thresholds (double digits on reallocated sectors+pending sectors is concerning, anything above 50 is replaced, anything that is rapidly climbing is replaced).

yep, I saw that the Acronis Disk Monitor which is installed last week or so, is reporting SMART.
The NAS log never reported anything regarding SMART: just a "one line", here it is :

Mon May 19 07:42:48 PDT 2014
Disk failure detected.

OMG
Same again, another disk failure

Fri Jun 20 00:03:01 PDT 2014
Disk failure detected.

This time is HD3
Disk 3 ST3000DM001-1CH166 2794 GB (28 °C / 82 °F, Write-cache On). Status: Spare inactive

Note that the SMART info box comes out empty (presumably because the disk is inactive).
Is this all what is kept in the logs? is there a more comprehensive log kept somewhere alse, or accessible in another way that I don't know?

The NAS is still on, btw. And come to think of it, last night the NAS fan was quite noisy, I looked at it and I think that it was resynching, and yes the HD3 led was flashing, but my head was into another pc (I was disconnecting HD1 after the testing, and one drive is not seen at boot-up).
Last time around I switched NAS off. What should I do? Should I switch it off before removing tray3 ? (I know that it says "inactive", but may stilll be powered..??)
Incidentally, I thought that NAS is supposed to send you a mail to warn you of faults, and my recollection is that I tested it and it was working..... :(


Below are the comments to your reply which I wrote earlier, before thinking of adding the warning line from NAS and discovering the new fault; they are not as important in view of the new fault, but they are still relevant with regards of diagnostic software

Thankfully (or is that the case ?) SMART is not reporting any issues, nor it did in the case of my HD1, no triggers, nothing (well I had a SMART issue loooooong ago and MAXTOR sent me a new disk before the old one failed, but this is the time when a 40Gb disk on a PC was HUGE, and the HDs carried a 80000h or 5y guarantee, or something like that).

regarding the failure thresholds - you must have other diags which allow to do so (or maybe you wrote them yourself). I would be more than happy to do the same to be on the safe side, but I don't have such tools, nor I know where to get it.... the view so far was that, if the disk passed the vendor diags, than it should be considered OK, so I never researched any more: there are other HD tools which seem to do all sort of magic on HDs, but I do not know which one is reliable and which one is not. Expecially after using Victoria, which seemed to produce different results depending if the software was installed on the pc, or it was run off a "miniXP" loaded from a CD (which may have different disk controller drivers -? ).

btw, is it better to upgrade the firmware now, before hot-inserting the newly cleaned HD1 in bay4, or viceversa? Or it is immaterial?

What is the warranty status of your unit? Would you be willing to try a different drive model? (for instance a WDC "Red" 3 TB drive?)

No. I just look at the SMART stats - either on the NAS or on Windows (with acronis disk monitor).

What firmware are you running?

I just checked the firmware, it is on RAIDiator 5.3.9, and I have downloaded 5.3.10 which I will install shortly, but there seem to be no relevant changes / bug fixes, only enhancements to cater for newer systems.

I don't know about the warranty status of this unit (HD1 was out of warranty). I'll check in a minute (I don't have the serial no until I remove it, NAS shows it in the SMART infos which are blanc as the disk is inactive); I am not sure about SEAGATE response, considering that it is not a "NAS unit.

Should I hot-remove HD3 or it is better to power down NAS first? I can repower NAS afterwards, no resynching to do since there is nothing to resynch...

All NV+ v2 systems should still be under warranty (which is 3 years from purchase). The product was launched in the fall of 2011, so there aren't any systems more than three years old.

The warranty is not transferable, so if you didn't purchase new you aren't covered.

I suggest that you engage support next, and not try to do anything more yourself.

BTW, in the future I suggest you get NAS disks (WDC Red are on the HCL). They have 3 year warranties, not the usual 1 for consumer drives, They don't cost much more.

my NAS is ~2years old, so it should be under warranty. But I am in the UK, so shipping could be an issue, which is why I think at it as my last port of call.

bad news for the 104, if it happens to be faulty. Surely it was troublesome, we were calling support two hours after installation

I hear you regarding "NAS grade" HDs, I might have learnt my lesson there

Still, with one HD just reformatted, ready in my hand and a "failed" one inactive inside NAS with a non-redundant X-RAID, I think that the first thing to do is to
a) unpower NAS
b) remove HD3 (now faulty) from bay3
c) repower NAS
d) hot-insert HD1 in bay3, hence calling for a resynch
e) while HD1 re-synch, run diagnostics on failed HD3 and take appropriate steps depending form the results, but most likely end up performing another full ERASE with Seatools.

meanwhile contact NETGEAR support, as well as investigate warranty claims towards Seagate regarding HD3 (note that HD1 did NOT fail the Seagate SeaTools diagnostics, so they would have been under no obbligation - it did not matter anyway as it was out of warranty).

I assume that the firmware update form 5.3.9 to 5.3.10 can wait after re-synching has finished.
Any thoughts on these actions?
Thanks again for all your time, berillio

forgot to say that I am investigating why I got no mail alert from NAS. True that the yahoo password might have been old, but even after changing it, mail failed to arrive. Changing the setting to "internal" made the mail depart happily from the NAS, but it was never delivered anyhow. I am investigating other option as I speak

This is why... https://help.yahoo.com/kb/email-service ... 24016.html

gmail should work. So maybe sign up for a gmail account, and use that to send. You can continue to list the yahoo account as a recipient.

I just managed to get yahoo to work. I just did not expect to put the email address three times. it worked, and it did it twice.
I could not use gmail: according to this browser, apparently the password is wrong. but when I put that password in my tablet few weeks ago, it was accepted.

Was my plan of action for NAS OK?
