我的 Western Digital My World Book White Light NAS 硬盘停止工作。它有一个 1TB 磁盘。
起初，我收到以下错误：卷状态 - 卷“DataVolume”不存在
然后 NAS 拒绝启动。
因此我从 NAS 中移除了磁盘并使用 SATA 转 USB 电缆将其连接到我的 Ubuntu 笔记本电脑。
运行 TestDisk 返回以下内容：

当我运行 testdisk 时，结果表显示所有条目前面都有 D，除了最后一个带有 P
我做了更深入的扫描，花了一整天的时间。
结果如下：
Disk /dev/sdb - 1000 GB / 931 GiB - CHS 121601 255 63
Check the harddisk size: HD jumpers settings, BIOS detection...
The harddisk (1000 GB / 931 GiB) seems too small! (< 1965 GB / 1830 GiB)

这段话有几千行......
有人可以告知这是什么意思吗？更重要的是，我的数据是否可以恢复以及如何恢复？
非常感谢
答案1
该磁盘是 XFS 磁盘
zh.wikipedia.org/wiki/XFS
使用
NAS 数据恢复 http://www.runtime.org/nas-recovery.htm
或提升 XFS 5.8 的数据恢复能力 http://www.softpedia.com/get/System/Back-Up-and-Recovery/Raise-Data-Recovery-for-XFS.shtml
我可以看到我的数据。获得许可证仅需 20.00 英镑左右。所以这似乎是可行的方法。
希望这对其他人有帮助。
