最近,我在 Acer Aspire S5 超級本上遇到了 Windows 7 啟動問題。啟動之前,系統指示其中一個實體磁碟(超級本在預先安裝的 RAID0 配置中具有兩個 128 GB SSD)有問題 - 並且在啟動時 Windows 進入藍屏死機模式。
我基本上想在重新格式化這些磁碟並重新安裝 Ubuntu 之前從磁碟恢復我的資料。
使用 USB 記憶棒,我能夠啟動 Ubuntu(無需安裝),並且在使用“磁碟”查看時能夠看到這兩個磁碟(並且這兩個磁碟都顯示為健康,儘管有壞扇區)。
fdisk -l 指令的輸出如下:
ubuntu@ubuntu:~$ sudo fdisk -l /dev/sda

我嘗試使用“dmraid -ay”安裝 raid(基於 Intel MATRIX Raid)
ubuntu@ubuntu:~$ sudo dmraid -ay
ERROR: isw: wrong number of devices in RAID set "isw_bbdaaaifgc_Aspire S5-391" [1/2] on /dev/sdb
RAID set "isw_bbdaaaifgc_Aspire S5-391" was not activated
附加輸入:
ubuntu@ubuntu:~$ sudo dmraid -r
/dev/sdb: isw, "isw_bbdaaaifgc", GROUP, ok, 250069678 sectors, data@ 0
如何將磁碟掛載到原始 RAID0 配置中?
