弱弱的问个问题，我在Mac系统下运行了fsck命令，显示如下
GeoffreymatoMacBook-Pro:~ Geoffrey$ sudo fsck -fy
Password:
** /dev/rdisk0s2
** Root file system
Executing fsck_hfs (version diskdev_cmds-540.1~25).
** Verifying volume when it is mounted with write access.
Journal need to be replayed but volume is read-only
** Checking Journaled HFS Plus volume.
The volume name is Macintosh HD
** Checking extents overflow file.

Incorrect number of thread records

Invalid leaf record count

** Checking extended attributes file.
Incorrect number of extended attributes

** Checking volume bitmap.

/dev/rdisk0s2 (hfs) EXITED WITH SIGNAL 8
但是我运行磁盘工具里面的硬盘监测却说磁盘没有问题，这是为什么？是否有人可以帮忙解释下这些错误的意思？非常感谢！
