我的 DELL 笔记本电脑在 Ubuntu 20.04 上崩溃后，目前在启动时卡住了。我尝试在 ubuntu live USB 上运行 fsdk，但是当我在 linux 文件系统分区上运行命令时，sudo fsck -y -f /dev/nvme0n1p3我只得到以下输出：
fsck from util-linux 2.34
fdisk -l 命令返回 3 个分区：
/dev/nvm0n1p1，513M，EFI 系统
/dev/nvm0n1p2，732M，Linux 文件系统
/dev/nvm0n1p3，952G，Linux 文件系统
以下是 sudo parted -l 的输出：
Warning: The driver descriptor says the physical block size is 2048 bytes, but
Linux says it is 512 bytes.
