Patches and discussion for Ensoniq VFX family

my floppy disk conked out on me.  I found a drive from an old ibm xt 
that worked for a while, but now it too is only reading the disks half 
of the time.  Has anyone had any success finding a drive that will work 
more than half of the time? or better yet, has any one had any success 
with a cd drive?
