为什么我的U盘无法挂载？/dev/sda 上的坏超级块

  • 772

我检查了lshw

sudo lshw -C disk
  *-namespace               
       description: NVMe namespace
       physical id: 1
       logical name: /dev/nvme0n1

          physical id: 0
          logical name: /dev/sda
          size: 57GiB (61GB)

lsblk 只显示

sda           8:0    1  57.6G  0 disk

我试着挂载

sudo mount /dev/sda /mnt/mydrive
mount: /mnt/mydrive: wrong fs type, bad option, bad superblock on /dev/sda, missing codepage or helper program, or other error.

如何检查错误的选项或错误的超级块？

sudo file -sk /dev/sda
/dev/sda: data

Disk /dev/sda: 57.64 GiB, 61872793600 bytes, 120845300 sectors
Disk model: DataTraveler 3.0

Sector size (logical/physical): 512 bytes / 512 bytes

    sda代表整个磁盘，而我确定你想挂载一个单独的分区。sudo fdisk -l将显示所有这些。

    Linux 完美地允许将整个磁盘用作分区，但包括 Microsoft Windows 在内的其他操作系统将无法使用它们。
