Yes, I have.
I checked the SD-Card also, it's ok on my PC and my Mac...
Meanwhile I have 'fixed' it by putting in the good old real floppy into the Amiga 1000, it just wasn't the same with the SD as with real disks, i had the feeling the Amiga1000 should stay as original as possible.
But I still have the problem with my A1200 sometimes. Readings disks is no problems, but when surfing in the frontend i get this error, but it's very rare.
So nothing is 'fixed'.
I thought that a floppy emulator on an A1200 wasn't not very usefull : You have an harddisk, you can use WHDLoad...
May i ask you what do you do with the HxC on the A1200 ?
