Donny, I don't think that is the best use of that hard drive....the 40 Gig Toshiba will fit nicely in your K/B T-1 T-2, don't know about Keton or Korg or whatever K/B you are using now....you can find out but asking here. The external H/D cases mainly use a reg H/D not laptop. I think that is your problem, not compatible....
