I have a dgr 3.5" magneto-optical drive that takes the standard 3.5"
128 MB cartridges, and it's worked pretty well up until now. And,
as far as I can tell, the drive is still working fine, but one of
the cartridges (only one out of four) refuses to mount. It was
formatted properly, same as the other three, with FWB's HDT Lite,
and I've been using it without fail for some time. For a while,
my computer was out of commission, so I moved the drive to an SE
running system 6.05, and it worked fine. When I switched the drive
back to my IIcx, however, this one cartridge refused to mount. It
goes in and sounds like it's mounting, but then it clicks a few
times, finally spinning down as if it's about to eject the disk, 
but it then instantly spins up again to try again. If I hold the 
eject button in, it eventually spits out. But it will NOT mount,
no matter what I do. All the others work fine, even those I used when
the drive was on the SE (I didn't expect any problems with any of
them).

This cartridge hasn't been unduly abused, exposed to any temperature
extremes or anything... does anyone have an idea why this reputedly
indestructible medium might suddenly go sour on me? I have a LOT of
vital data on there, and I really don't want to revert to an expensive
data recovery service to get it off...

ANY help or suggestions would be MUCH appreciated.
