Problem solved I have mailed you bud
For anyone else thinking of buying one for the A500 running WB 1.3 it wont auto boot unless you have WB 2.0 or later so you just hold the mouse buttons down and use the early boot menu and select DF1
so KMtech adapter as suggested above wont boot either
Obviously you can open it up and place the internal drive with the Gotek one.
something to bear in mind for the A500 WB 1.3 owners out there.
