System is Arch Linux. NTFS-3G is installed. I have had this problem on Gnome (Nautilus) and KDE (Dolphin). I already tried fixing it with Testdisk. No success. Any help is appreciated.
UPDATE: I have re-formatted the disk and it is working now. Thank you for all your suggestions and tips.
thats probably
partpar of the course for the arch experienceid check if Udisks is installed and running.
Off topic, but the phrase you are looking for is “Par for the course” :)
Thanks, I will do that. Currently reading the ArchWiki entry on udisks.
