WD 出了Idle Mode Update 和 WDSpinUp Utilities 預防及解決Green Power HD 潛在問題

先前有人在 SilentPCReview 提出他的 WD Green Power WD10EACS 硬碟Load Cycle Count Value 過高 (>87000)，他計算出以他的使用狀況，他的Green Power WD10EACS 硬碟會在 200 至 300 天就會超過預計壽命的界限，這位作者的系統似乎是 low-usage media server machines running Linux。

禍源是由於硬碟超過了 8 秒 Inactive 後就會進入 low power (Idle 3 mode) 狀態，但系統就每若干秒將硬碟叫醒，重覆不斷。

可能基於上述或其他原因 WD 出了兩個 Utility 解決問題。
  
1.  RE2GP Idle Mode Update Utility
http://support.wdc.com/product/d ... 609&sid=113〈=en
  
RE2GP Idle Mode Update Utility 只限用於這三個型號
  
WD1000FYPS-01ZKB0
WD7500AYPS-01ZKB0
WD7501AYPS-01ZKB0

2. WDSpinUp Utility
http://support.wdc.com/product/d ... 609&sid=114〈=en
This is a DOS Level utility to configure the low current spinup feature for Western Digital GreenPower(TM) drives. It allows spinup current to be configured to low or super low. It reports spinup current setting (low or super low).


WD Support > Knowledge Base
Why the S.M.A.R.T Attribute 193 Load/Unload counter increases for the WD1000FYPS-01ZKB0, WD7500AYPS-01ZKB0, WD7501AYPS-01ZKB0 drives.
  

Affected Models:
WD1000FYPS-01ZKB0,
WD7500AYPS-01ZKB0,
WD7501AYPS-01ZKB0

Symptom:
WD drives are designed to reduce power consumption, in part by positioning the heads in a park position (unloading the heads) and turning off unnecessary electronics, resulting in substantial power savings. WD defines this mode as Idle 3.

Some utilities, operating systems, and applications, such as 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. This effectively negates the power-saving advantages of low-power drives, such as Western Digital’s RE2GP, and artificially increases the number of load-unload cycles.

Solution:
The number of systems using such applications and utilities is limited and customers can resolve this symptom by optimizing their systems to not wake up the drives unnecessarily every 10 to 30 seconds or so, thereby gaining substantial power savings and eliminating superfluous activity.

Most customers, when made aware of the unnecessary activity caused by their systems, have modified their utility, operating systems, or applications to take advantage of Western Digital's advanced power-saving mode. Other customers have requested a utility (See link below) to modify the behavior of the drive to wait longer before invoking Idle 3 mode. Although such a change eliminates significant power savings during periods of inactivity. This update is described in WD's Process Change Notice PCN 2579-701324-A02 (see attached PDF file).
Please click on this link, RE2GP Idle Mode Update Utility, to download the utility.

NOTE: The update also supports a low-power spin-up feature optimized for highly energy efficient, large scale storage applications, which is enabled using a utility, WDSpinUp Utility, also available at the RE2GP Download page.

上次死雞, 今次WD
點解近期0地HD禁多問題0既:funk:

即是 Caviar Green 没有問題?

現在並沒有證據有 WD Green Power 硬碟會因上述原因而過早失效，只是因 SMART 的 load/unload cycles 數字會很快超過規格的 300,000 load/unload cycles 。新的 firmware/utility 有減低這個數字的作用。

事實上08年4月已有人將這個現像提了出來。

有人說 SpeedFan 會令 load/unload cycles 數值大大增加。
