I would say, from my experience with other parallel-port disk devices of
various types, that the SuperDisk almost certainly uses EPP mode, and will
work substantially slower if ECP mode (or ECP+EPP mode) is selected.
You should be able to see something in your dmesg output from the SuperDisk's
protocol driver that tells you what mode it's currently using - compare it
when the port is in EPP mode and ECP mode.
Example from my EPAT-based SyQuest drive:
paride: version 1.06 installed (parport)
paride: epat registered as protocol 0
pd: pd version 1.05, major 45, cluster 64, nice 0
epat_init_protopda: Sharing parport0 at 0x378
pda: epat 1.02, Shuttle EPAT chip c3 at 0x378, mode 5 (EPP-32), delay 0
pda: SyQuest EZ230A, master, 450560 blocks [220M], (880/16/32), removable
You'd be using the pf driver instead of pd, I would think. Just look for
something similar, or grep for "pda".
