Hello Community!

I am using MorphOS 3.2 on a MAC Mini G4. Whenever I use my card reader everything works fine. I can access the volumes and transfer data, but after some minutes the volumes disappear and a poseidon popup tells me "Warning: Dead Device". As I am still a MorphOS noob I do not know what to do?

Please help me. I am happy about any information I can get. As it functions in general (for max. 3 minutes) I think it is all about the settings!? If you are so kind to answer to my question beare in mind that I am an absolute MorphOS noob without any Amiga experience. But I love MOS and step after step I am getting deeper into it. ;)
