New Image

[dazulrich]

If you know of other images where this works. maybe you can try and contact those trying to find out what they did to make this work better. or whether they use a particular version of the ntfs 3g driver. (which is a 3rd party opensource driver). Maybe the new version is incompatible, who knows. But you can try finding that info, and depending on what the answers are, Bonkel might be able to implement for you to test then.
Unless any other user with an AzboxHD and the same ntfs disk problem is interested in solving this, Zeini's recommendation to use ext3 or ext4 is the best alternativ suggestion at the moment.
Or you can try the user Fabry over on opensat4all forum , he once compiled a "kernel for powerusers" and he might have some insight into the ntfs quirks. (but as per his last post from July, he has no working Azbox or dev environment anymore)

---- some legwork ----
@Kapios: can you find out which image has stable ntfs support and what driver they are using. (maybe you can open the driver from your openspa image and see if you can find version info.

are you mounting the disk using the mount manager (via fstab), can you post the fstab entry?

@Bonkel, dein oe unterbau kommt von openpli? ich glaube die nutzen den ntfs treiber von meta-oe. (ntfs-3g-ntfsprogs_2013.1.13.bb)
openatv zb, hat eigenes bb und benutzt neueren treiber (ntfs-3g-ntfsprogs_2015.3.14.bb)
und laut Tuxera ist ntfs-3g_ntfsprogs-2016.2.22 aktuell.
