This is driving me crazy...\n\nDragon SY-K7V Dragon Plus.\n\nI had a RAID0 array running fine on IDE3/4 and CD-RW and DVD as\nmasters on IDE1/2. . Was given another hard drive, so thought I'd lose\nthe RAID and just have IDE1 master, IDE2 master & slave, and swap the\nopticals to IDE3/4.\n\nRead the manual, switched the jumpers, set the BIOS - checked it all\n20 times, all exactly as per manual. But the opticals are dead. If I\nunplug the 40-pin connectors, they 'work' - i.e. lights on, they\neject, but as soon as I plug the connector back in, they're dead. I\nknow they are ok, because I've just reinstalled XP by having HDD0 as\nmaster on IDE1 and HDD1 master and DVD slave on IDE2.\n\nHow the devil can I get IDE3/4 up and running? What am I missing?\n\nThanks and a pint for anyone who can help.\n\nDavid.
