磁盘实用程序错误地读取磁盘;将 ext4 视为 JHFS+ 并看到 Recovery HD

磁盘实用程序错误地读取磁盘;将 ext4 视为 JHFS+ 并看到 Recovery HD

因此,我在磁盘实用程序和 diskutil 中遇到了一些奇怪的问题。这不是问题(希望如此),但我只是想确保我不会走上磁盘损坏或故障的道路。这是我的磁盘实用程序读取硬盘的方式:

(如列表所示)

  • 磁盘描述:APPLE SSD SD0256F 介质
  • 总容量:251 GB(251,000,193,024 字节)
  • 连接总线:PCI
  • 写入状态:读/写
  • 类型和位置:固态磁盘,内部
  • SMART 状态:已验证
  • 分区图方案:GUID 分区表

分区如下:

  • 麦金塔高清
    • 格式:Mac OS 扩展(日志式)
    • 大小:202.66 GB
  • 高清恢复
    • 格式:Mac OS 扩展(日志式)
    • 大小:650 MB
  • 磁盘0s4
    • 格式:Mac OS 扩展(日志式)
    • 尺寸:46.8 GB
  • 磁盘0s6
    • 格式:Linux Swap
    • 大小:681.6 MB

我担心的原因有两点:1)Recovery HD 是可见的,我可能弄错了,但它不应该在磁盘工具中可见或安装,2)disk0s4 实际上是 ext4,而不是 JHFS+。

diskutil 列表的输出:

    /dev/disk0

我之前曾使用过 gdisk 将我的硬盘混合为 MBR/GPT,并安装了 Ubuntu 14.04。

有人知道为什么会这样吗?disk0s5 在哪里?这会是个问题吗?

gpt 有这个输出 -
