mhh . . .i haven't own an A3000/T but, the SCSI controller of the A3000 uses 2nd.scsi.device too?
I've just reistalled the XSurfIDE in Expansion: (yes i am a masochist) and then i've launched the "custom_NSD.rexx" script, that helps alot to enable all the working device on the system and i have this line in "Devs:NDSPatch.cfg":
DEVICE 2nd.scsi.device DEVICETYPE NSDEVTYPE_TRACKDISK VERSION 43 REVISION 22 ISNSD
Without XSurfIDE installed, this line is disabled.
Bye
