Can't duplicate any disk

[Pitou]

I might have narrowed down the issue and found the root cause.

I took a working Amiga gamedisk and wrote the Workbench 1.3 SCP image over that disk.

I booted up the disk and it's still the game that boot not the Workbench!

I took my scope and looked at pins 22 (Write data)  and 24 (Write Gate).

Pin 22 looks fine, I see the signal, however pin 24 (Wgate) is always High. Is that normal?

Could Duey be blown? (I'm sure I didn't connect the cable the wrong way)

What do you think?

Pitou!
