OK thanks, then that's my problem and I didn't write to that effect but one of my questions was if both drives had the software to run independently if swapped from other players. I had a hard time writing exactly what I wanted to ask and it shows I edited it a lot. I actually read that FAQ about upgrade but 'assumed' since the drive was already working another player it didn't need it.
Unfortunately I didn't pay attention when I took out the drive from the MkIIa, to put a larger drive, if it was a Master or Slave and it had actually been sitting on the bench for awhile before I decided to install it into the MkII b/c it's slave drive went bad (clicking).
From what your saying the drive I'm trying to use was/is a slave then and that's why it doesn't want to show up or work in Emplode.
OK thanks at least I know where to start, I'll look at the FAQ pages again.

Many thanks tfabris
