Hello!I fixed something in ide-floppy some time ago - when I bought LS-120 drive and software eject did not work. See http://lkml.org/lkml/2005/9/4/83
MO, WORM, {ZIP,ls120} drives if you are using the full capabilities, IDE tape drives, etc.
Sorry, I don't remember what capability the ls120 was using, but as of 2.6.12 it didn't work through the ide-floppy interface.
Then it's a bug in ide-floppy which should be fixed.
