Error on ntfs partition.

When I tried to sync my google drive on a ntfs partition, the following error occured.
After changing to ext4, no error occurs.

The fix for this should be very simple (do not throw exception when mtime change fails), but it's interesting that your ntfs volume does not allow changing mtime. Is it ntfs-3g?

[vitalif]

Just tested with ntfs-3g - there is no such error...

I tried again and I found the solution.
After adding fmask,uid to /etc/fstab item, it works correctly.

Before my /etc/fstab

UUID=0226D37B26D36E63 /media/windows  ntfs    defaults,umask=007,gid=46 0       0

After

UUID=0226D37B26D36E63 /media/windows  ntfs    defaults,umask=007,gid=46,fmask=111,uid=1000 0       0

Ok, so you weren't the owner of these files.
I think I'll remove the exception anyway because the mtime modifications are not necessary for grive to work.
