使用 cfdisk 将 vfat 转换为 linux，现在无法挂载它

使用 cfdisk，我将 vfat 拇指驱动器转换为 Linux，但现在无法安装该设备。以下是我尝试时发生的情况。

/home/g mount /dev/sdc1 /16gb
NTFS signature is missing.
Failed to mount '/dev/sdc1': Invalid argument
The device '/dev/sdc1' doesn't seem to have a valid NTFS.
Maybe the wrong device is used? Or the whole disk instead of a
partition (e.g. /dev/sda, not /dev/sda1)? Or the other way around?

答案1

cfdisk 创建分区。您仍需要格式化它们以匹配所需的文件系统。我不知道您对配置有什么想法，但假设您想格式化分区以在 EXT3 中工作：

mkfs.ext3 /dev/sdc1

然后你就可以尝试挂载了。

答案2

cfdisk和朋友只会更改分区表；它不会更改分区本身的内容。因此，如果您使用一个充满零的全新驱动器并向其写入新的分区表，分区本身仍将充满零，并且操作系统无法识别。

文件系统使用工具mkfs（“make filesystem”）进行初始化，其概要如下：

mkfs [options] [-t type fs-options] device [size]

对于您来说，要/dev/sdc1使用默认选项用新的 EXT3 文件系统初始化分区，您可以说：

mkfs -t ext3 /dev/sdc1

显然，这会抹去 中已经存在的所有数据/dev/sdc1。
