I think that's an entirely suitable technique... I'd be approved of over on 
the ClassicComp mailing list, anyway.

Ahhh, I see what you mean. I should, perhaps, have added that if I switched 
off or unplugged the drive subsequent to the hang, the 710 frees up again 
with a "device not present" error. So my assumption is tha 710's OK, and 
the drive isn't talking to it.

As far as I'm aware, with the exception of the "V" keytop snapping off, the 
710 is in full working order.

Apologies for any confusion caused.
Cheers, Ade.
