从 HSF+ USB 外部硬盘恢复文件，在 CentOS 7 上进行测试以进行诊断

笔记：

我的问题的结果与如何从损坏的硬盘修复损坏的 HFS+ 分区？

对于 ubuntu 的另一个结果： https://askubuntu.com/questions/955325/using-gpart-testdisk-to-recover-gpt-for-files-from-damaging-hfs-apple-hd

我有 USB、外置硬盘HSF+文件系统。

问题是我无法在 MAC 上提取我的文件macOS 塞拉利昂 10.12.6，甚至使用商业工具，例如：

  • 技术工具 Pro 9
  • 磁盘战士5
  • 盘钻
  • Data Rescue 4（现在我正在测试）。

在 macOS Sierra 上，我运行了以下命令：

  • diskutil verifyVolume /dev/disk2s2

    The volume ADATAHD could not be verified completely File system check exit code is 8 Error: -69845: File system verify or repair failed Underlying error: 8: Exec format error

  • diskutil RepairVolume /dev/disk2s2

    File system check exit code is 8 Updating boot support partitions for the volume as required Error: -69610: Error parsing fsck program XML format output Underlying error: 8: Exec format error

  • sudo fsck_hfs -fryd /dev/disk2s2

    unknown volume type primary MDB is at block 0 0x00 alternate MDB is at block 0 0x00 primary VHB is at block 0 0x00 alternate VHB is at block 0 0x00 sector size = 512 0x200 VolumeObject flags = 0x01 total sectors for volume = 1952853344 0x74662d60 total sectors for embedded volume = 0 0x00 CheckForClean - unknown volume type CheckHFS returned 6, fsmodified = 0

  • sudo gpt -r 显示磁盘0

    gpt show: unable to open device 'disk2': Resource busy

  • sudo diskutil Repair磁盘disk2

    Problems were encountered during repair of the partition map Error: -69808: Some information was unavailable during an internal lookup

我正在读这篇文章：如何从损坏的硬盘修复损坏的 HFS+ 分区？但错误代码不同！

我想知道你是否使用 CentOS 7 开始我的测试。

我的问题是在苹果上寻求解决方案。https://apple.stackexchange.com/questions/296151/recover-files-from-corrupted-external-usb-hd-macos-sierra

我把这个问题放在这里是因为我也想尝试使用 CentOS 7 端！

谢谢。
