Ubuntu 22.04.2 LTS系统下只读驱动器无法创建文件夹及修改路径问题求助

Hey there, let's work through this read-only drive issue step by step. I've tackled similar problems plenty of times, so here are the most practical fixes to try out:

• Check the drive's mount status
  First, let's confirm if the drive is actually mounted in read-only mode. Open a terminal and run:

  mount | grep /dev/sdXn
  

  Replace /dev/sdXn with your drive's identifier (you can find it using lsblk or df -hT). Look for the ro flag in the output—if it's there, remount the drive with read-write permissions:

  sudo mount -o remount,rw /dev/sdXn
  

  If you don't know the exact device path, you can also use the mount point (like /mnt/hdd):

  sudo mount -o remount,rw /mnt/hdd
  

• Verify file system permissions
  If the drive is mounted as rw but you still can't create folders, check the permissions of the mount directory. Run:

  ls -ld /path/to/mount/point
  

  Ensure your user account has write access (look for w in the user or group section). If not, change the ownership to your user:

  sudo chown -R $USER:$USER /path/to/mount/point
  

  For permanent fixes, you can add uid=$(id -u),gid=$(id -g) to the mount options in /etc/fstab so the drive always mounts with your user's permissions.

• Check for disk errors
  Linux often mounts drives as read-only to prevent data corruption if it detects file system errors. To fix this:

  1. First unmount the drive (skip this if it's your system drive):

     sudo umount /dev/sdXn
     

  2. Run the file system check:

     sudo fsck /dev/sdXn
     

  If it's your system drive, you'll need to boot from a Ubuntu Live USB, then run fsck on the system partition from there—since you can't fix a mounted system drive.

• Fix /etc/fstab configuration
  If the drive keeps mounting as read-only after reboot, check your /etc/fstab file. Open it with:

  sudo nano /etc/fstab
  

  Look for the line corresponding to your drive. Make sure the mount options include rw (not ro), and verify the UUID is correct (you can get the right UUID with blkid). Save the file (Ctrl+O) and exit (Ctrl+X), then reboot to test.

• NTFS drive-specific fix
  If your HDD is formatted as NTFS, Ubuntu might mount it as read-only by default if the ntfs-3g package isn't installed. Install it with:

  sudo apt update && sudo apt install ntfs-3g
  

  Then remount the drive, and you should have write access.
