Help understanding SMART error

[russb123]

I am getting a email from my nas4free with a email heading of:

SMART error (FailedReadSmartSelfTestLog) detected on host: mynas

Does this mean there is a read error on the disk or a error reading the log file?

Here is the total error message:

Code: Select all

This message was generated by the smartd daemon running on:

   host name:  mynas
   DNS domain: local

The following warning/error was logged by the smartd daemon:

I do not fully understand all the data above, but I cannot figure out why I am getting this error email. Thanks for any advice.

I am no expert in S.M.A.R.T., so I cannot explain what is the error you are getting.
But by reading your values, I see an alarming info, so thought I should mention it.. From your smart result:

Code: Select all

9   Power_On_Hours          0x0032   099   099   000    Old_age   Always       -       874
12  Power_Cycle_Count       0x0032   100   100   000    Old_age   Always       -       6
193 Load_Cycle_Count        0x0032   181   181   000    Old_age   Always       -       57177

This, if I am not mistaken - please wait for someone else to confirm this, too - means that :

1. Your Hard Disk is powered on for 874 hours
2. You have turned off this machine 6 times since you have installed this disk
3. Your hard disk's heads have parked/unparked 57177 times

This is not good. It seems to me that your wd "green" features are parking the disk heads very frequently - Calculations show that in average your disk heads have parked once every 55 seconds.
You should change this setting for your disk with wdidle.exe, otherwise I am afraid that your disk will die soon!
Just for reference I am posting similar results from one of my NAS's disks (a really old one):

Code: Select all

  
9   Power_On_Hours          0x0032   041   041   000    Old_age   Always       -       22151
12  Power_Cycle_Count       0x0032   100   100   020    Old_age   Always       -       208
193 Load_Cycle_Count        0x0032   099   099   000    Old_age   Always       -       13991

As you can see, in my case:

1. My disk is working for 22151 hours (This means almost 3 years - For the last year the machine is a few hours a day on, real age of the disk is more than 4 years)
2. I have turned off this machine 208 times since I have installed this disk
3. My hard disk's heads have parked/unparked 13991 times. So, in average the heads are parked one every one and a half hours

Hi ChriZathensand Russb123,

I am wondering too, from the SMART report it is a WD RED (WDC WD30EFRX) which shouldn't park the heads as often as the Greens :-/
I am shocked about the values Russb123 gets, too.

My WD REDs are now up for 6300 hours (one year with breaks in between) and have just 944 load cycles.

On the other hand, the drives are designed for 600.000 cycles, so it shouldn't be too late to use wdidle, I just wonder
a) if it (wdidle) works with reds, too and
b) what is the cause for this heavy parking?

I would recommend:
- backup the data
- run an extended self test (use Hiren's boot CD and boot with Parted Magic -run the SMART test program)
- return the disk on warranty and get a new one

Cheers,

Crowi

Seems to be a problem with the new WD Reds:
viewtopic.php?f=59&t=6055

[ChriZathens]

3-4 months back I bought a WD Red to keep as cold spare (it is still sealed)
Seems that I will take the Seagate NAS HDD route from now on, if WD is making disks worse instead of better... (the whole "need NAS disks" topic is in question, TBH, but this is another story...)

[rootmeansqr]

I have three (3) WD Red 2TB Drives, purchased around Aug-2013, and all are performing nominally.
So far, I'm very happy with my WD Reds.
Perhaps I got this batch right before they started to ship the Reds with the 8 second parking.

it does actually wear out the drives faster
