Yes, we have tried that, but WD refuses to support Linux systems. Anyways, 95% of the disks shipped with Bubba Two are not RE2-drives, so we would need a fix for all drives. However, getting help from WD with this seems difficult.

We are working on a general "keep-busy" tool that automatically installs on your Bubbas with an update, and only runs on drives that need it. Sorry for it to take so long though.

Hi,

Just one question that may not be pertinent to the particular issues at stake, but it is related to it.

Does this problem apply to USB mounted drives?
Meaning, I have two 1TB My Book WD usb external storage devices and they are affected by this, and that was confirmed by WD.
I can not access smartools command output in this setup (usb) so ... I wonder if, by being mounted by USB they would be affected by the load_cycle as if they where used directly in the SATA bus ...


Regards

Hi,

I'm new here but I was drawn to this forum by my WD's devilish sounds. I have a WD5000AACS-00ZUB0 drive and while in idle state it creates sounds like this: wd5000aacs.mp3.

Sometimes it will cause those sounds in low usage as well for instance: copying files at 100-200k/sec.

My smartctl says pretty much the same all the time:

Code: Select all

vir1:~# date; smartctl -d ata -a /dev/sda | grep -i -E '(load_cycle|temp|Power_On_Hours|Device Model)'
Mon Apr 20 07:32:02 CEST 2009
Device Model:     WDC WD5000AACS-00ZUB0
  9 Power_On_Hours          0x0032   098   098   000    Old_age   Always       -       1780
193 Load_Cycle_Count        0x0032   195   195   000    Old_age   Always       -       17860
194 Temperature_Celsius     0x0022   104   091   000    Old_age   Always       -       43
My smart extended tests are all OK and no problems reading or writing on drive has occurred so far.

Anyone has a similar experience / problem? 'cause this one is really going on my nerves...

necromncr,

This is new to me, I have never heard such a sound. Hard to know what it is, but to be safe I'd exchange the disk as a warrnaty repair. You can do that either by WD, or directly by us. Contact us at support@excito.com for further instructions.

Best Regards,

Hello Johannes,

Have the excito team found a solution to the hardisk increasing load cycles?
I'm running a sript to keep the disk awaike, but everytime we restart bubba two we have to re insert the script

well.. that's not good :/ can I trust this hd anymore for backups? (edit: well I suppose I should, since having a copy beats having only the original.. still that LC-count kinda sucks bozons)

and for some reason testing fails..

Code: Select all

smartctl -t long /dev/sda
Long (extended) offline self test failed [unsupported field in scsi command]

Hi again all,

A brief upddate from us; you should know that we are working on this, but it showed more complex than we first thought and it will be another some time before we release the fix. I hope for your patience, and until then, please use the script suggested above to prevent the problem from progressing.

Generally, a high load cycle count does not seem to be an immediate large risk, many users have reported LCC of a factor 10 above the maximum recommended without having any problems.

I have also updated the title of this thread to show that the issue only applies to old disks.

Hoping for your patience...
//Johannes

Excito,

It seems that with the last update the keep busy script doesn't work anymore.

I made the script executable en ran it as described as you told in this forum.
It worked before the update.

After a renew boot it is going up again.

What am I doing wrong??

Hi Puma,
Maybe you want to share the content of your script before someone can comment?

Hello,

Script I use:

#!/bin/bash
#workaround for the green drive WD problem loadcycles

while [ true ];do
sleep 5
tail /var/log/messages > /tmp/wdfix
done

Exe
chmod +x /home/storage/extern/wd_stop_unload.sh

RUN with
nohup /home/storage/extern/wd_stop_unload.sh &


I checked it with "top" I can see every few seconds the wd_stop_unload but it keeps increasing!!!
This didn't happen before. at least I think!

Hi Puma,

The problem you encounter was identified and a solution was found about 2 months ago in this very forum thread. It has to do with using the /tmp directory which seems to have some kind of caching which avoids repeated physical disk writing (causing the unexpected counter increase...).

See topic http://forum.excito.net/viewtopic.php?p=7337#p7337

That should solve your issue (thanks to Peter).

Wow, this was a busy thread that died very quickly wasn't it? I found this while searching for something else and would like to know if there was an official Excito fix. I was aware of this problem in *nix world when it happened but I didn't think it was still a problem as most distros implemented fixes.

That being said, my own Bubba2 which is just over a month old has an LCC of nearly 64000. That puts me on target to hit the 300000 barrier in less than four months from now which is a bit of a worry as I'm not sure my drive will be covered by its warranty (n.b. I have a WD Green Power 1 TB that was bought from a third party).

I need to buy new hard drives, one will be used a primary and the second as a backup hard drive.

I have no considerations buying 1 TB or 2 TB, either one suits my purposes.

What would you guys recommend, go for a specific WD Green Power model or another brand??

Hi all,

Sorry for not closing this thread earlier. The problem is considered fixed now as all new drives since more than a year has this fix implemented. For users who suspect their drives (purchased from us prior to 31/11-2008) are suffering from this, we'll gladly swap these against new drives. Just contact us at support@excito.com and we'll help you out there.

Best Regards,

And to add, we did thoroughly investigate possible fixes, but couldn't find any that didn't affect other functions in a negative way, so we decided not to.
