Server 上的 RAID 1 壞掉一顆,這顆分割成系統槽和一個資料槽。
換上一顆一樣大小的硬碟之後(型號不同,原來型號已經買不到),
在 Windows 上按下新增鏡像後,就跳出一個錯誤訊息「存放指定磁碟區之延伸的所有磁碟都必須具有相同且有效的磁區大小。」
換了另一顆較大的硬碟也是一樣的結果,
google 上查了這個錯誤,也找不到怎麼處理,想請問是不是有其他大大曾經遇過類似問題?
另外,我查了一下目前還正常的那顆硬碟,他的物理磁區大小是 512 Bytes,
後面換上去的都是 4096 Bytes,不能 rebuild 跟這個有關係嗎?
如果有關的話,物理磁區大小有辦法更改嗎?不行的話,是不是就不能重建 RAID 了?

請問 512E 和 512N 指的是什麼?
關於512e這個格式的說明如下
https://en.wikipedia.org/wiki/Advanced_Format#512e
實體磁區是4K,邏輯上模擬成512-byte(*8)

512e
Many host computer hardware and software components assume the hard drive is configured around 512-byte sector boundaries. This includes a broad range of items including chipsets, operating systems, database engines, hard drive partitioning and imaging tools, backup and file system utilities as well as a small fraction of other software applications. In order to maintain compatibility with legacy computing components, many hard disk drive suppliers support Advanced Format technologies on the recording media coupled with 512-byte conversion firmware. Hard drives configured with 4096-byte physical sectors with 512-byte firmware are referred to as Advanced Format 512e, or 512 emulation drives.

硬碟規格上從哪裡可以看出是 512N 或 512E?
