我從 Mybook World 2（白色 LED）中提取了磁碟。該設備只有這塊 1TB SATA 磁碟，並且使用 RAID1。是的，這很奇怪，但是 WD 即使對於 1 磁碟配置也啟用了 RAID。
這是來自 disktype 的報告：

重要的文件都在sdb4中。
我嘗試安裝它：
sudo mount -t xfs -o ro /dev/sdb4 /media/recovery/
但它沒有說檔案系統錯誤，或超級塊損壞。
我也嘗試過 mdadm：
sudo mdadm --assemble /dev/md4 /dev/sdb4
mdadm: no recogniseable superblock on /dev/sdb4
mdadm: /dev/sdb4 has no superblock - assembly aborted
有存取 XFS 檔案系統的想法嗎？
