I tried to put Scene settings on another SD-card then the provided 16Mb SD-card. But apprently the HD-100 can't read 512Mb for example? Or is it because other files then the SCN files are on the card. Is the camera confused seeing other files? Anyone else some experiences with other SD-cards?

no matter how big the sd card is, the HD100/110 can only read four scene files

I found my problem through a windows computer. I saw the files were put as read-only. That explained why the camera couldn't write anymore.
Case closed.
