I've been mounting it with sudo mount -t ntfs -o umask=000 /dev/sda1 "/media/My Book" but for some reason it now says mount: warning: /media/My Book/ seems to be mounted read-only when I do so, and ls -l shows it's correct. The drive has its own power supply and it works fine with my laptop, so I think the problem must be with the Pi. What am I doing wrong?

Update: Just to be clear, that command used to work, and it's read-only for EVERYONE, even root:

$ ls -l /media
total 8
dr-xr-xr-x 1 root root 4096 Apr 28 11:11 My Book

The contents appear the same way.

Update 2: Probably found the cause. From /var/log/syslog:

May 17 19:37:52 raspberrypi kernel: [   64.688724] NTFS driver 2.1.30 [Flags: R/W MODULE].
May 17 19:37:52 raspberrypi kernel: [   65.195397] NTFS volume version 3.1.
May 17 19:37:52 raspberrypi kernel: [   65.195439] NTFS-fs error (device sda1): load_system_files(): Volume is dirty.  Mounting read-only.  Run chkdsk and mount in Windows.

Probably should've tried looking there before...

ntfs is a kernel-based, read-only ntfs driver (actually you can modify a file or its attributes, but not its size).

Try mount -t ntfs-3g, which relies on fuse (Filesystem in USErspace).

  • mount: unknown filesystem type 'ntfs-3g' According to a comment on this question the ntfs option uses ntfs-3g. And the commanad I listed used to work...but now it doesn't.

Running chkdsk E: /F on Windows fixed it.

@Zelda64fan You need to install this ntfs-3g module on your distro to make it work.

  • You should expand your answer to include how to install the module and why you believe that will fix the problem. if you read the other comments and answers I don't think your suggestion is the answer tot he OP's question.

  • The OP answered his own question, so you should update your answer to show how to figure out what to do and how to do it.
