Acorn Winchester 10MB disk repair

Post by pauldjagger » Sat Oct 17, 2020 5:00 pm

I have an Acorn Winchester 10MB disk drive that powers up without issue but fails to respond to commands from an attached BBC Master. There appears to be no obvious mechanical issue. Any ideas on how best to diagnose the root cause?

Have you got the right ROM(s) installed to drive it? It will probably need ADFS at least.

So the Master will have ADFS by default, but if you've got a "MultiOS" or equivalent, it may well have the ADFS which has been patched for IDE, and consequently won't work with an old Winchester?

Has it been known to work? Do you just get a flashing cursor after *ADFS and nothing ever happens?

Can you see the LEDs inside through the front grille? The controller is on the left and should light up at power on and stay on until it detects the drive. It will also flicker every time the Beeb is reset. When trying to access the disc, the controller light will be on until it finishes the operation or times out.

The drive itself is on the right and should have its activity light wired onto the front panel, which should light up when there's a disc access.
