I too am running an A3000 with 2 Quantum 105 HDs, and the ASDG dual serial card. I am always transfering files using my USRobotics V.32bis (read 14.4+ transfers) and local to a PC at 38.4K, and while I am transfering I am always doing other things in the backround, multiple windows, opening and closing them, etc, and I NEVER have any transfer problems. > >I haven't tried using the internal serial port but I expect the >same things happen then.

NO WAY!!! I have been running multiple HDs as well as a SCSI Tape drive, all at once even, without any lockup or any other such failures!!!!!!!!!!! > >Having more than one harddisk connected to my A3000 certainly >DOES cause problems with this machine.

Sorry you are having problems. What is the second HD? Is it properly interfaced? Terminated?

Again, what drives is he running? Are they interfaced properly? I have been running multiple drives with 2 versions of Kickstart (both 1.3 and 2.x) for a long time now without problem, (still on an old release of 2.x), fill us in, maybe there is some other problem somewhere else that someone on the net can point out.
