you cannot mix different speed drives on the same ide cable ...
	- similarly, you cannot mix 2MB buffer disks with 8MB buffer disks
	( the hw doesnt know what to do )

put your 40GB on its own ide cable as Master.. make sure its 80-
conductor.. and that your bios supports it ( reports it as a 40GB drive )

leave the working prev 1GB drive alone.. on its own cable

and as posted earlier, make sure you have DMA enabled and -X at the right
