Disk drive diagnostic tool are they definitive ?
Hi All
Can anyone let me know if the disk drive diagnostic tools are definitive. If I run the Western Digital Data LifeGuard Diagnostics tool on my 4 x 2Tb WD-20EARS CAVIAR GREEN 2TB 64MB 7200 SAT and they all came back as passed, can I yes 100% that the disk are ok ?
Or is there a possibly they could still be bad ?
Thanks
Alan

Vendor thresholds for bad sectors are much higher than the ones I personally use. So I always look at the smart data (which Lifeguard will show you) in addition to their pass/fail. If you see a trend of increasing reallocated sectors, then the drive is almost certainly failing even if it hasn't reached the vendor threshold yet.alan27 wrote: Hi All

I have tested drives I knew were failing, but the vendor tools still passed them. Waited another week, and then they failed. So in my experience, if the vendor tools report a fail, then the drive is certainly bad. However, if they report a pass, it does not guarantee that the drive is good.
Are you having issues with your drives? Maybe you could post the details.- Also what version of RAIDiator is on your NV+? You need 4.1.7 or later for compatibility with those drives.
- Hi mdgm
It's all part of an ongoing issue I have with my NV + not booting which I have a thred running here for : viewtopic.php?f=20&t=58275
Just trying to elimate as much as possible. 3 of the 4 drives have been tested so far and all have passed, just disk 1 to go , but didn't look at the increasing reallocated sectors part. So will have to put them all back in and have a look once disk one has finished. (7 hours to go :-( ) thanks for the info yes I am on 4.1.7. The disk are only 10 month old just find it hard to believe 4 disk fail at the same time, but looks like there ok ..... Maybe.
Once this disk is done I'll pull the report for each disk and post them here, so you can see if that's ok , if thats ok .If you get a spare min to have a look at my main issue that would also be most appreciated :-)
Thanks again for you time and help
Alan - I'm just a user like you and don't know much about SMART. Feel free to post the drive SMART stats (I wouldn't post drive serial numbers though, so edit those out).
The vendors tests are the best tests available but they're not guaranteed to pick up if a drive has issues. - There is an interesting paper on SMART here: http://static.googleusercontent.com/ext ... ilures.pdf
- Thanks guys, will follow your advice thanks agin
- Ok so out of the 4 x 2Tb WD-20EARS CAVIAR GREEN 2TB , Disk 1 failed. Disk 2, 3, 4 passed . But I’m very worried that the remaining disk are on their way out , as they were all purchased at the same time , maybe a bad batch ? any advice you could give me here would be most appreciated.
Here is the SMART logs for each disk
Disk 1 , this is the one that failed

What I find odd ( to my untrained eye ) is Disk 1 looks ok in the logs , no errors like 2,3,4 but yet that’s the one the failed .... also 2,3,4 are almost identical 12 errors ? hmmm? I have also read about ATA Error Counts , Reallocated Sector Counts and Load Cycle Count as ones to look out for as a guide to if you hard drive is on its way out ....
Is 12 ATA errors bad ? is a Load Cycle Count of disk 2: 362613 Disk 3: 421549 Disk 4: 423058 something I should be worrying about ? these hard drives are only 10 month old .
Any help / advice you can give me here would be most appreciated.
Alan - Did your NAS come with firmware older than 4.1.7? If so that would explain why you have those ATA errors. As for the Load Cycle Count don't worry about it, those numbers are meant to be high.
What does your partition.log look like? - Hi Mdgm
Thanks again, for taking the time to look and help, yes your right , it came with 4.1.6, last Dec then upgrade 2 ish month after that to 4.1.7 . cool so there looking good at the mo :-)

What can you tell from that then ? (hope all is good there also) - This confirms your unit came with firmware older than 4.1.7.
Due to the lack of 4k sector alignment you may be experiencing poor write performance.
