I've just aquired several magneto optical hard drives with the 5.25" cassette still in them. How do I get them out without destroying the drive or cassette ? There's a small hole below the lower right of the cassette, like the one on a bare cd player, that would line up with the eject button, if the front was still in place. On a cd player, a small wire poked in there releases the disc mechanism. I hesitate to try this until anyone can advise that I wont be causing any damage. Apart from this, I can't see what is holding the cassette in place. Many thanks.
