NTFS 4 Terabyte drive problems on FreeBSD?

2013-02-12 Thread Scott Ballantyne
Hi,

I'm trying to mount a 4 TB drive (The Seagate Backup-Plus) on FreeBSD
9.0 Generic, using 

mount -t ntfs /dev/da0s1 /mnt

It fails with:

g_vfs_done() da1s1[READ(offset=0, length=1042)]error=22
mount_ntfs: /dev/da1s1 bad argument

However, I can mount a 2 TB ntfs drive with no problem, using the same
command, and the 4TB drive checks out fine in Windows. 

Does anyone know if this limitation exists, and if there is a
work-around? I only need READ access to this drive.

Thanks a lot!
Scott

That's a strange length (1042).  I would have expected a multiple of the
device blocksize (4096 in the case of the Backup Plus).

You can try the sysutils/fusefs-ntfs port; the ntfs code in the base system
hasn't had much work done on it lately.
