I have an FreeAgent GoFlex Drive that I would like to save data to via my Raspberry Pi 3. I'm able to view jpegs from the drive, but not save data to it. When I attempt to change permissions, I get the following error:

chmod 755 FreeAgent\ GoFlex\ Drive/
chmod: changing permisssons of 'FreeAgent GoFlex Drive/': Read-only file system

What do I do in order to be able to save to it? I have data on there, so formatting is not an option.

    Please post the output of mount | grep FreeAgent while it is mounted. – Ned64 Feb 17 '18 at 12:24
  • mount | grep FreeAgent\ GoFlex\ Drive/ gives no output – matsuo_basho Feb 17 '18 at 22:08

This could work: Try to dismount (can be done with umount) it, restart PC and login as root or do sudo chroot 755 YOUR_HARD_DISK_DRIVE (if it gets mounted, dismount it again) and then manually mount it (create a subdir in /mnt/ example "cd /mnt/, mkdir mntpnt1") then use mount command to mount it in /mnt/ (or wherever you like).

Also is there any documentation from Hard Disk Drive's manufacturer? If yes, make sure you read it.


Viola mount -o remount,rw /path/to/remount

  • sudo mount -o remount,rw FreeAgent\ GoFlex\ Drive/ gives following error: mount: cannot remount /dev/sda1 read-write, is write-protected – matsuo_basho Feb 17 '18 at 22:10
  • It might have a hardware switch that needs to be flipped, have you looked at the user manual? – jas- Feb 18 '18 at 6:07
