Do you mean that they automatically eject when you shut down?

If so, I have a fix: format the disk using Apple HD SC Setup (the patched 7.3.5 version). Then the machine will think it's a regular hard disk, and it WON'T eject it at shutdown/restart!

It works wonderfully with 100MB disks (it's MUCH more compatible, too); not sure about the 250's, though. I'd imagine they'd be similar.
