When I try to mount the drive, I get this:

cmu-234701:~ Justin$ ntfs-3g /dev/disk0s1 /Volumes/ntfs -ovolname="Music"
$LogFile indicates unclean shutdown (0, 0)
Failed to mount '/dev/disk0s1': Operation not supported
Mount is denied because NTFS is marked to be in use. Choose one action:

Choice 1: If you have Windows then disconnect the external devices by
clicking on the 'Safely Remove Hardware' icon in the Windows
taskbar then shutdown Windows cleanly.

Choice 2: If you don't have Windows then you can use the 'force' option for
your own responsibility. For example type on the command line:

mount -t ntfs-3g /dev/disk0s1 /Volumes/ntfs -o force

Or add the option to the relevant row in the /etc/fstab file:

/dev/disk0s1 /Volumes/ntfs ntfs-3g defaults,force 0 0

And then, when I try to force mount, I get this:

cmu-234701:~ Justin$ mount -t ntfs-3g /dev/disk0s1 /Volumes/ntfs -o force
usage: mount [-dfruvw] [-o options] [-t ufs | external_type] special node
mount [-adfruvw] [-t ufs | external_type]
mount [-dfruvw] special | node
cmu-234701:~ Justin$

If anyone could tell me what I'm doing wrong, I'd greatly appreciate it.

Apparently you're using FreeBSD mount which it seems doesn't support the Linux mount syntax. Please try the below and let me know if it works and I'll update the ntfs-3g advise:


If it still doesn't work then try this one:


Thanks, Szaka

cmu-234701:~ Justin$ mount -o force -t ntfs-3g /dev/disk1s1 /Volumes/Windows
mount: exec /usr/sbin/mount_ntfs-3g for /Volumes/Windows: No such file or directory
cmu-234701:~ Justin$ mount -t ntfs-3g -o force /dev/disk1s1 /Volumes/Windowsmount: exec /usr/sbin/mount_ntfs-3g for /Volumes/Windows: No such file or directory

I'm on a MacBookPro if that helps any. Trying to mount a 300GB and 500GB external from my old PC.

You mistyped the correct /Volumes/ntfs as /Volumes/Windows. Please type exactly, or even better copy-paste, what was suggested above.

Make also sure that you still have the /Volumes/ntfs directory.

You also must do this as the root user.
