我正在尝试从运行 Windows 但无法启动的 HP 笔记本电脑中恢复数据。我能够使用 Knoppix 启动它。
$ fdisk /dev/sda
Command (m for help): p

/dev/sda3和的安装/dev/sda4有效，但似乎它们与大C:分区不对应。
安装/dev/sda1失败/dev/sda2。这是预料之中的事吗？
$ mount -o ro /dev/sda1 /mnt/sda1
mount: wrong fs type, bad option, bad superblock on /dev/sda1,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try
dmesg | tail or so.
$ mount -o ro /dev/sda2 /mnt/sda2

这看起来像是 HP 恢复分区：
/mnt/sda4$ ls
boot Desktop.ini hp HP_WSD.dat recovery RM_Reserve
bootmgr FactoryUpdate HPSF_Rep.txt preload $RECYCLE.BIN System Volume Information
因此，您可能希望sda3与大C:分区（windows 文件夹、用户文件夹）相对应。但事实似乎并非如此：
/mnt/sda3$ ls
bci2k bci data Data EEG BCI $RECYCLE.BIN System Volume Information
有任何想法吗？
