SMART Data says "Disk is Being Used Outside Design Parameters"... Huh?


Hello All,

I've been seeing this error every couple of days, I have probably seen it 3 or 4 times now...
Probably because the Drive is external and I don't connect it everyday, otherwise I'd probably see it more often.


OS: OpenSuSE 11.4 (2.6.37.6-0.11-default)

I get a pop-up windows that tells me there is an error with one of my Hard Disks.
The first error I'm seeing is:
"Disk is Being Used Outside Design Parameters"
Not exactly sure what that means...

And then if I click on the Alert/Error Icon down in the "Notification Area" it brings up OpenSUSE's "Disk Utility" application. From there it shows me a listing of "Attributes" that I guess it runs checks on using the "SMART" Data program.

The "attribute" that I'm seeing it show an error for is this (It's in a GUI Window so I can't exactly copy/paste it in):
Code:
ID  |                  ATTRIBUTE                         |  ASSESSMENT | VALUE
----|----------------------------------------------------|-------------|-------
240 |  Head Flying Hours (Time while head is positioning)|      N/A    | .....
That one above is the ONLY one that is showing in RED.
The strange thing is, is that it is an SSD Drive which has no spinning heads in it and hence how could it have an error with that...?

As I'm writing this, the Error Icon in the Notification Area has gone away, but I'm sure it will be back.
B.T.W. The SSD Drive is an external Drive that is hooked up through a Hard Drive Docking Station connected through eSTATA.

Any thoughts why I would even see this error with a Solid State Drive..?

Thanks in Advance,
Matt

Hi,

SSD manufacture & model may help to identify the problem.

Look at this Corsair sticky: Interpreting SMART Data on Corsair Force Series SSDs for some helpful information. Most manufactures do provide a knowledge base for their SSD models.

Which Gnu/Linux are you using? Do you know which scheduler the kernel is using for the 'SSD' device?

Look at: https://www.linuxquestions.org/quest...ml#post4586247 for some helpful information. Slackware specific but the technique should be applicable generally.

Hey onebuck, thanks for your reply..!

Sorry, I should have mentioned that in my original post, I just thought that it was weird that
a Solid State Drive would/could have had an error relating to a "Flying Head" Error/Warning... I'm
assuming that, that error has to do with the "swing" arm and head that reads the platter of a "normal"
HDD? Strange...

SSD Specs:
Manufacturer: Kingston (SSDNow 100)
Model: SV100S2
Size: 128 GB

Basically I just use the SSD Drive for a couple VMs, and not really any document storage or what not...
But, I will definitely head over to Kingston's Website and check out what they have for support.

Thanks Again,
Matt

Hi,

Which distribution? Possibly could still be related to scheduler and not Smartctl.

Look at: http://www.kingston.com/us/support/t...?model=SV100S2 if that is your drive.

Code:
# cat /sys/block/sda/queue/scheduler
[noop] deadline cfq
My scheduler(Slackware 13.37) on the Dell M5030 laptop is set to 'noop' which is a FIFO. Some distributions set the default to 'cfq'. Some users will use 'deadline' but no gain here since there are no moving heads on a SSD. If you use 'deadline' a performance hit. You can set specific drives to the scheduler of choice, does not have to be system wide.

You can email Kingston tech support from: http://www.kingston.com/us/support/t...?model=SV100S2 on the right side of page.

Shoot... Sorry I meant to put that in the last reply.

OS: OpenSUSE 11.4 (i586)
Kernel: 2.6.37.6-0.11-default

Code:
> cat /sys/block/sda/queue/scheduler
noop deadline [cfq]
Is the scheduler what controls Disk IO?
Also, what does "cfq" stand for..?

Thanks Again,
Matt

Hi,

Linux Kernel I/O schedulers;

Completely Fair Queuing (CFQ) "is an I/O scheduler for the Linux kernel which was written in 2003 by Jens Axboe."

Deadline "The goal of the Deadline scheduler is to guarantee a start service time for a request"

Noop "The NOOP scheduler inserts all incoming I/O requests into a simple FIFO queue and implements request merging."
