Mac 硬盘未能装载

大佬们的前车之鉴
I was having the exact same issue where unmountDisk would work fine but eject would result in the "timed out" message. I finally found a suggestion to see if fsck was holding the disk hostage. A quick ps aux | grep fsck revealed that indeed it was hijacking the disk/volume as soon as it was plugged in. sudo pkill -f fsck (or just kill with the PID if you prefer) immediately allowed the volume to be mounted.
看不懂没关系！！！ 接下来，
来喽 来喽 他真的来喽！！！
遇见事情不要慌 干就完了 上命令 ！！！
1、先使用diskutil list 查看自己宗卷名字
next ---->
ps aux | grep fsck
然后杀掉所有fsck的进程 sudo pkill -f fsck
so，我的桌面上就已经展示我的硬盘图标了，如果你的还不可以请重新插入你心爱的硬盘试一下！！！！
