Thanks Toni. Must have missed that in my searches. Will give it a go.
With regards to your real A1200, what size hard drive is it?
Have you tried formatting it fully to see if you get the error?
Only 1.3 Gig. A bog standard format throws up no errors. I have no idea how old it is, possibly it is just slowly dying. No idea about cache or any of the other factors. The RAM works fine on the 4MB setting.
Thanks for the quick response. Off to find a winuae beta.
