After resizing an NTFS partition on an external GPT drive using Gparted the volume doesn't seem to automount on Ubuntu anymore (or other distributions, like OSMC). It has worked fine previously. It still seems to work fine in macOS and Windows 10 where I've been able to browse it just fine and use it as a backup target.
- Gnome's Disks calls the partition "Partition 2 - 419 GB Unknown". Apparently it can't read the partition name nor the volume label, because neither is named "Partition 2". It also can't seem to determine the partition type, which is listed as Unknown.
- Another NTFS partition on the same drive is being automounted correctly. Its label and type are being identified properly in Disks. Those are the only two partitions in the GPT.
gdiskreports that both these partitions' types are
0700 - Microsoft basic data. I don't know what more Gnome Disks needs apart from that.
- I used
gdiskto remove the customary time bomb (a.k.a. hybrid MBR) that Gparted always so thoughtfully puts on any protective MBR drive it touches. After a reboot it turned out to have no effect, which is reasonable since Disks never used the MBR anyway.
- I could mount and browse files using
mount -t ntfs -o nls=utf8,umask=0222 /dev/sdc2 ./mount-point. As part of the operation it mentioned an unclean file system, and that it was "Fixing..." Apparently it worked, since the volume was accessible afterwards, but it still will not automount after a reboot.
chkdsk /fin Windows 10 reports no errors.
I'm unsure why only Ubuntu (and other linux based OSes) can't seem to identify the partition type and automount the volume anymore. Is there an easy way to check?
Did I forget something?
