Q10 Pro HDD not in network on laptop

[H@ns]

Hello everybody,

My Q10 Pro is in my LAN network, recently i placed an internal SD harddisk in it.
On my television I can see the USB sticks and the SD disk in mediaplayer and folder managers.
I also can copy or move media on the Q10 looking at the TV and it plays media correctly.

On my laptop in the network I can see the Q10 and the fixed Q10 folders Video, Music etc.

But I can't see the other storage like HDD and USB to copy media to my Q10 via network.
Samba is on and I tried several options with Android apps and in Windows 10 on my laptop.
Can someone give me a clue what to do to work on the storage in Q10 Pro via laptop on network?

Many thanx in advance!
