請問是相容性問題是2顆硬碟之間的相容性嗎?
還是跟硬碟陣列外接盒跟硬碟的相容性?
我自己是用S牌 直接給你官方說法 你參考
請問要如何解決 Western Digital Green Power 系列硬碟『載入/載出週期』過高的情況？
解答：
您可以透過 WDIDLE3 計時器修改來解決載入/載出週期。此解決方案適用於企業硬碟包含：WD VelociRaptor、WD RE3、WD RE2-GP 以及 WD RE2，與桌面硬碟包含：WD Caviar® Black™ 、WD Caviar® Blue™ 以及 WD Caviar® Green™。修改 WDIDLE3 計時器的步驟如下：
下載WDIDLE3程式 點我。
建立 USB DOS 開機程式，( 請參閱http://klcintw4.blogspot.com/2007/03/usb.html )
將 WD 硬碟連接至電腦主機板。
重新開機，進入 DOS 作業系統。
輸入 WDIDLE3/S300。
畫面出現：『Idle 3計時器已啟動，週期設定五分鐘』，表示操作成功。
如果仍無法操作或對此問題保有疑慮，請接洽Western Digital。
事實上...有人改了還是會掉HD ...

When an error is found on a desktop edition hard drive, the drive will enter into a deep recovery cycle to attempt to repair the error, recover the data from the problematic area, and then reallocate a dedicated area to replace the problematic area. This process can take up to 2 minutes depending on the severity of the issue. Most RAID controllers allow a very short amount of time for a hard drive to recover from an error. If a hard drive takes too long to complete this process, the drive will be dropped from the RAID array. Most RAID controllers allow from 7 to 15 seconds for error recovery before dropping a hard drive from an array. Western Digital does not recommend installing desktop edition hard drives in an enterprise environment (on a RAID controller).
Western Digital RAID edition hard drives have a feature called TLER (Time Limited Error Recovery) which stops the hard drive from entering into a deep recovery cycle. The hard drive will only spend 7 seconds to attempt to recover. This means that the hard drive will not be dropped from a RAID array. While TLER is designed for RAID environments, a drive with TLER enabled will work with no performance decrease when used in non-RAID environments.
