why would it take a look at the disk in the drive and "care" whether or not that set of platters (or flimsy plastic thing in a hard case, depending--but platters in the case of Jaz) with magnetic coating on it can be taken out of its drive or not? How do the electronics of the card give a hoot?

The electronics don't, because it is electronically a SCSI device. My guess is that it is seen by the controller as a hard disk, which is not normally removable. But the device can accept some commands which a removable disk, such as a CD-ROM, can also accept. It may also be sending commands back the other way, like "I've got a disk inserted" or "Someone just pressed my eject button". If the controller thinks the device is a standard hard disk and then starts receiving these commands, it may get confused and hang the SCSI chain. The newer ROM version probably accounts for this type of device which is why it can handle it.

Having said all that, I know very little about this so I'm just guessing :-)
