Samba is needed to access Amiga drives from the PC. But a 68030 with 16 MB RAM is far too underpowered for Samba. Even on a 68060 Samba is very slow.
I used Samba on my old 030 A1200 with 32mb. It was a pain to set up and it was slow as hell but, it did the job.
I think I ended up using Amiga explorer to move files from my PC cause it was quick and easy.
