NTFS-3G volume unmounts and immediately remounts

[Mikael Nilsson]

Binary package hint: gnome-mount

I've used feisty, gnome-mount and ntfs-3g successfully for a month or two now.

Recently, my external USB drive with label "WD Passport" fails to unmount, and immediately remounts. Two meaningless errors pop up.

What happens is that the volume actually unmounts (from looking at the output of "mount" and of /media/.hal_fstab), but then immediately remounts.

It used to work, now it does not.

Here's the debug output

Found it.

Same here

Unfortunately after unmounting, a remount with writing enabled is not possible any more. This renders any NTFS disk unwritable under Linux.

Correction: If you are quick you can unplug the disk during dismounted phase. Then writing is still possible. (Doubtfully this is a reasonable solution though).

Ammendment:

manually umount-ing the device works.

maybe its a GNOME error after all ?

I was going to report the same error.

And yes, manually unmounting works.

I was afraid that perhaps it would matter whether Nautilus was open to that drive, but it doesn't. Manually unmounting always seems to work.
