20231218在Ubuntu18.04下以EXT4格式化HDD
2023/12/18 17:24

缘起：
编译一个Android10+大概要200GB，编译10+个Android10+的SDK，3TB的HDD机械硬盘就估计会被填满了！
如果使用rm -rf *这个命令将SDK一个一个逐个地删除，估计2小时+（可能大半天就没有了。）
想过WINDOWS下的解决方式，直接格式化！

Ubuntu - 硬盘分区、格式化、自动挂载配置

在终端窗口中输入如下命令：
sudo mount -t ext4 /dev/sdb /devdata
说明：
指定硬盘分区文件系统类型为ext4 ，同时将 /dev/sdb 分区挂载到目录 /devdata。

结果：重启之后，结果ubuntu黑屏了，原因不明。我直接格式化【系统】了，【然后】重装【整台电脑的WIN10/Ubuntu20.04】了！
【步骤应该没有问题呀！^_】

稳妥的步骤：

rootroot@rootroot-X99-Turbo:/etc$ cp fstab.bak1 fstab
rootroot@rootroot-X99-Turbo:/etc$ sudo reboot

rootroot@rootroot-X99-Turbo:/etc$ sudo mkfs -t ext4 /dev/sda
【然后重新挂载/dev/sda即可！】
