Yes, it automatically spins down. But that doesn't seems to matter.

Might be. (Its my assumption, too)
Firmware Rev: 1314 (If anybody likes to know)

Well, that doesn't help me a lot... ;-)
What about invalidation of the buffer cache if a removable media is unmounted ?
Even if the failure for the disc change detection lies at the firmware.
I think its a *very* bad idea to cache fs buffers after umount, causing
a disaster. (Overwriting the superblock, free block list,... etc.)
This should never happen, even if there is no correct disc change detection.
Btw: The fs is ext2.
