Why are my files on the external drive suddenly read-only?

Asked By CuriousCoder42 On

I've been using Zorin and everything was working perfectly with my external drive where I keep my Dropbox folder. Recently, I tried to set up my /dev/sda2 device to auto-mount on startup, but now the files are all read-only. I can open the files, but I can't save any changes. I checked the permissions, and they seem to be set correctly for everyone. What can I do to fix this issue and regain write access?

If your drive is showing as read-only, double-check the mount point and your permissions. You can run `ls -al` in the terminal to see who owns the mount point and if you have write permissions. If that’s all okay, you can change permissions directly with `sudo chmod 777 /mnt/YourMountpoint`. Also, consider switching the filesystem to ext4 or xfs if you’re not planning to use Windows at all.

First off, check what filesystem your external drive is using. If it's NTFS, there's a good chance that the filesystem needs to be checked and repaired using Windows. Linux might be mounting it as read-only if it detects issues. After repairing it in Windows, safely eject the drive before plugging it back into Linux. Also, make sure Windows hibernation is disabled, and consider using the `ntfsfix` command in Linux specifically for NTFS drives.

I ran into the same issue, and it was easier to fix than I thought! I was using an NTFS drive for Dropbox on Windows, and after trying to set it to automount in Linux, it just became read-only. I resolved it by using the Disks application to unmount the partition and then selecting Repair Filesystem. That restored my access to normal write capabilities. Just a heads-up though: always proceed with caution when repairing NTFS filesystems in Linux; the tools are pretty basic.
