I had this running perfectly from my old Dietpi jessie system but I want to run stretch. Why now does it decide not to work any more?
The same code used to add the hard drives aren’t being accepted any more.
I am stupid. It didn’t auto install ntfs-3g
Fix
apt-get install ntfs-3g -y
Jep NTFS and HFS support packages are not pre-installed any more on DietPi systems. Instead they will be automatically installed, when dietpi-drive_manager is started while such a drive/fs is attached.
Indeed a slight comfort loss for users that like to configure their drives manually, otherwise most do not need NTFS or HFS support, so we can safe drive space and NTFS background service for them.
