Micron m4 SSD FW to fix 5184 hours bug - 儲存設備

※ 引述《Shougon (光)》之銘言：
: http://www.crucial.com/support/firmware.aspx
: Version: 0309
: Release Date: 01/13/2012
: Change Log:
: ‧Changes made in version 0002 (m4 can be updated to revision 0309 directly
: from either revision 0001, 0002, or 0009)
: ‧Correct a condition where an incorrect response to a SMART counter will
: cause the m4 drive to become unresponsive after 5184 hours of Power-on time.
: The drive will recover after a power cycle, however, this failure will
: repeat once per hour after reaching this point. The condition will allow
: the end user to successfully update firmware, and poses no risk to user or
: system data stored on the drive.
: This firmware update is STRONGLY RECOMMENDED for drives in the field.
: Although the failure mode due to the SMART Power On Hours counter poses
: no risk to saved user data, the failure mode can become repetitive, and
: pose a nuisance to the end user. If the end user has not yet observed
: this failure mode, this update is required to prevent it from happening.
: If you are using a SAS Expander please do not download this Firmware.
: As soon as we have a Firmware Update that will work in these applications
: we will release it.
: 修復 5184 小時後開始 BSoD 的問題，就算目前沒問題的 user 一樣要 update。

剛剛升級上去
我的環境因為有RAID(M4 64G x4 / RAID 5)，所以比較複雜一點。
一開始把機器關機，拔掉RAID卡，紀錄接線的順序(其實本來就有編號，再做一次心安的)
拔掉RAID卡上的sata線
插入燒好映像檔的隨身碟、把四顆SSD接到版子上的SATA1-4
開機進BIOS、調整ahci-->IDE-->reboot-->從隨身碟開機
好，問題來了，我有四顆SSD，但是只有顯示一顆出來...

我是很願意相信原廠應該有考慮到拿來做RAID的情況
理論上不應該出現只有抓到一個的情況？？
但是因為我這台是online的機器 ，停機時間說好只有半小時
所以我也沒有辦法再去測試換線換port等等
直接再把機器shutdown，只單接一顆SSD
這次開機一樣是抓到一顆(廢話)
輸入 yes 後就順利update
然後換第2顆、第3顆、第4顆....
通通update完成，依照順序接回raid 卡，然後祈禱一下...
開機...順利進入作業系統，以上完畢。
