2TB WD20EARS HCL Advanced Format 4k Sectors TLER LCC WDidle3

EDIT: This thread was written before the Readynas group had recognized and addressed the WD Advanced Format HDD's. An issue that remains to this day is the massive LCC(Load Cycle Count) increases due to the original HDD Firmware.
I believe the end of year 2012 WD Red drives address most of the issues that plagued the WD20EARS and WD20EARX but I have not confirmed this.

The LLC (Load Cycle Count) for a majority of my drives has now approached 3Million. Yes Three Million.

There appears to be a New WD20EARS-00MVWB0 which has 3 Platters. As yet untested. http://forums.vr-zone.com/hardware-aren ... etter.html

WDidle3_1_05.zip info works with WD20EARS HDD's viewtopic.php?p=233472#p233472

WD20eaRs HDD's 4KB Alignment issues appears to be FIXED with firmware 4.2.12-T9 viewtopic.php?p=238394#p238394
The SPARC 4KB Fixed Alignment firmware version is looking to be done by July 2010 as mentioned here. viewtopic.php?p=242472#p242472

2TB WD20EARS HCL, Advanced Format 4k Sectors, TLER(Time Limited Error Recovery), LCC(Load_Cycle_Count) info

After reading a fair bit online about the new WD Caviar Green/GP HDD's by WD such as the WD20EARS and their newish 4k sector size,
I am left wondering if the ReadyNAS firmware(existing or Beta) has been updated for this new HDD Sector design?
Could one of the JEDI or anyone else please comment on the following information?

Sorry for what appears like a jumble of information following but its hard to know where to start,
when all i really want is for it to be on the HCL as it is the only WD HDD commonly available here in Melbourne Australia.

This is a very good clear explaination about the 4096B Sector size that replace the historical 512B size
http://www.anandtech.com/show/2888
With the emulation of 512B sectors, there’s the risk that a partition could be misaligned compared to the 4K physical sectors - where it would be unwittingly started in the middle of such a sector. As a result, the clusters of a file system on that partition would end up straddling 4K sectors, which would cause performance problems.
In order to solve the misalignment issue, Western Digital is offering two solutions. The first solution for correcting misaligned partitions is specifically geared towards Win 5.x, and that is an option on the drive itself to use an offset. Through the jumpering of pins 7 and 8 on an Advanced Format drive, the drive controller will use a +1 offset, resolving Win 5.xx’s insistence on starting the first partition at LBA 63 by actually starting it at LBA 64, an aligned position. This is exactly the kind of crude hack it sounds like since it means the operating system is no longer writing to the sector it thinks its writing to, but it’s simple to activate and effective in solving the issue so long as only a single partition is being used. If multiple partitions are being used, then this offset cannot be used as it can negatively impact the later partitions. The offset can also not be removed without repartitioning the drive, as the removal of the offset would break the partition table.

Western Digital Advanced Format What WD have to say which is not very helpful when it comes to linux.
http://www.wdc.com/en/products/advancedformat/index.asp

I have read that TLER is enabled on the WD20EARS. Can anyone here confirm(x seconds) as info is conflicting?
Also the old HDD utilities for spinup and TLER are no longer supported by WD for the EARS drives.

From what I have read do not use the 7-8 Jumper for XP compatibility mode due to more than single partition issue.

ReadyNAS related Fix? Is this already implemented?
Linux Fix according to WD knowledge base
http://wdc.custhelp.com/cgi-bin/wdc.cfg ... faqid=5357
Problem: The Load/Unload counter for S.M.A.R.T Attribute 193 continues to increase under some distributions of the Linux Operating system.
Affected Models: WD20EADS, WD20EARS, WD15EADS, WD15EARS, WD10EADS, WD10EARS, WD8000AARS, WD7500AADS, WD7500AARS, WD6400AADS, WD6400AARS, WD5000AADS, WD5000AARS
some implementations of Linux, for example, are not optimized for low power storage devices and can cause our drives to wake up at a higher rate than normal.
Solution:

The number of systems using such applications and utilities is limited and customers can resolve this symptom by optimizing their systems with the following three options depending on requirements.

Do not wake up the drives unnecessarily every 10 to 30 seconds or so, thereby gaining substantial power savings and eliminating excess activity. Increasing logging to every 2 minutes would result in 525,600 minutes per year or 262,800 cycles per year. Increase to 5 minutes and cycles would not even be a factor.

a. Linux users: Decrease the logging message

i. Examine your /etc/syslog.conf file for unnecessary logging activity and to optimize its performance. If you don't want to log any system activity, consider disabling syslogd and klogd entirely; or, at the very least, minimize the amount of logging your system performs. You can also prefix each entry with the minus sign (-) to omit syncing the file after each log entry. This will log anything with a priority of info or higher, but lower than warning, to /var/log/messages or /var/log/mail without needing to sync to disk after each write. Since we want to keep all messages with a priority of warning, this will be logged to a different file without disabling disk syncing (to prevent data loss in the event of a system crash).
*.warning /var/log/syslog
*.info;*.!warning;mail.none -/var/log/messages
mail.info;mail.!warning -/var/log/mailii. Another item to be aware of is the -- MARK -- messages that syslogd(8) writes. This will affect your hard drive inactivity settings. You can simply disable this by running syslogd(8) with:

if [ -x /usr/sbin/syslogd -a -x /usr/sbin/klogd ]; then
# '-m 0' disabled 'MARK' messages
/usr/sbin/syslogd -m 0
sleep 1
# '-c 3' displays errors on console
# '-x' turns off broken EIP translation
/usr/sbin/klogd -c 3 -x
fi
b. Modify OS power management timers in control panel

Disable Advanced power management using standard ATA command (Uses more power as turns off all low power modes but results in no load/unload cycles)

Linux users add following (hdparm -B 255 /dev/sdX where X is your hard drive device)
ATA users can disable APM usually controlled via BIOS and/or OS.ATA users can disable APM usually controlled via BIOS and/or OS.

Set Idle3 to max time (effectively turns off load/unload power saving feature thus will use more power) per below link

Any Links I have missed please add, especially form here.

Re: 2TB WD20EARS HCL, Advanced Format 4k Sectors, TLER, LCC

Well a week on I have installed 6x2TB WD20EARS HDDs into A ReadyNas Pro Pioneer and Its running fine for the moment,
with the exception of the LCC (Load Cycle Count) which is rising too fast for anybodys liking.

I read somewhere that the WD20EARS is designed for around 1,000,000 LCC and at the rate of around 3000 per day thats 1000000/3000=333.3' Days for design life failure..
A guesstimation forcast of less than a year before harddrive failures.

NOT GOOD! and NOT Acceptable!!
Who has the solution, Netgear, infrant or Western Digital?

3. Can this be made as a Selectable option in FrontView (Please)?

4. Can the Jedi (anyone here) confirm/deny the use of WDidle3_1_05.zip or other tools as working with WD20EARS HDDs in the ReadyNasPro?

I actually spoke with Netgear directly about the WD20EARS and was told that the drive would be ok
I especially spoke to netgear about the 4k cluster size and about possible mis-alignment problems in regards to WD's new Advanced Formating and they said no problem....

I'm not so sure as I'm only getting 22MB/s writes (8Gb file copy) with jumbo frames on Giga LAN through a netgear GS108 but I do get 75MB/s reads for a 8GB file copy over CIFS while running XRaid2 dual redundancy.

The LCC was going to be the issue long term as Western Digital states 1 Million cycles life when currently i am projecting 2-3 years for the drives as its looking like over 300,000 per year guaranteed.

Unfortunatly the spec page from WD state otherwise.
http://www.wdc.com/wdproducts/library/SpecSheet/ENG/2879-701229.pdf
Load/unload cycles 300,000
Does this actually=LCC ?

http://www.wdc.com/en/products/products.asp?DriveID=773


I also read somewhere that the WD20EARS does have TLER (time limed error recovery) which was in contrast to wiki, but wiki is not always right.

I am running 6 x WD20EARS with jumbo frames and the jumbo does make a difference.

Thats next.

I'm feeling that running XRaid2 with 2 x redundancy might be significantly slower than single redundancy. I didn't really research as I needed double redundancy and that was that as my budget was limited....
Hmmmm its hard to say limited budget and $3400 in the same breath,
but u get what i mean. RNPP 8 x WD20EARS HDD

With Win7 and netgear GS108 Jumbo and using CIFS,
I'm getting around 25 MB/s for files less than a gig so I'm thinking its memory related.

Re: 2TB WD20EARS HCL, Advanced Format 4k Sectors, TLER, LCC

I still don't like the look of that Load Cycle Count. I still wouldn't recommend using WD Green disks because of that.

You can try to use the WDIDLE3 utility but it will void the warranty of your disks, I believe and may damage them.

EDIT: WDIDLE3 will not void your warranty as per HanSolo and WD conversation.

I tend to agree about not purchasing these drives in future,
but in Melbourne that was all they had and I had the old x6/600 lose a drive so i bit the bullet and got the ReadyNasProPioneer RNPP that I am now having serious thoughts about taking back for a refund.
I did speak to netgear and they confirmed the WD20EARS and Advanced Format with their top level engineer.
I specifically asked about 4k cluster size and Advanced Format mis-alignment performance issues.

Question @mdgm.
This seems slower than expected... Is this normal for RAID Level X-RAID2, 6 disks (with dual redundancy).???

I don't have a Pro yet, but I'd like to get one. There are a number of factors which can effect speeds such as the performance settings you've made in Frontview, the speed of the hard disk in your computer, processor speed etc., what you are transferring e.g. large or small files? There is also other traffic on the network and other tasks being performed by the ReadyNas and I'm sure some other things I haven't mentioned to take into account.

Anyway, the Definitive Guide although it doesn't have speeds for dual-redundancy (it does have speeds for RAID-6) suggests that the Pro is capable of fairly similar read/write speeds (well a lot more similar than what yours are). Your read speeds look fairly good (not knowing your setup), but the write speeds do look a bit low.

Not at a reasonable price, not when you need 8 x TheSameTypeBrand, Not when its nearly a 400Km return trip.

This test apeared to take much longer (1 hour) than it should of and I personally believe it is due to the 4k cluster overlap issues with Advanced Format.

I also think I need DD results for each individual HDD, to help pin down a single drive or highlight that its all of them.

Can someone else who has these HDD's please give this add-on a try. The add-on does not require any changes to SSH.
After it has finished running.... Maybe 1hr unit the Status Log states the Speed and test completed.
The results will be in a folder called benchmark in the ReadyNasPro which can be accessed via command prompt running of
net use P: \\ip-of-readynas\c /user:admin
and then going to P: Drive on My Computer.
Once you have copied the benchmark folder out to desktop remember to right click on P: drive and Disconnect the Mapped network Drive.
