Hi,
i have a first gen iLiad and haven't used it a long time. Yesterday i tried to look at some PDFs i have and filled my CF card with content. I inserted in the iLiad, opened the CF but it showed up abolultley empty. I tried a different CF card, same. Then i tried a SD card. Same. USB Stick works.
I also tried to restore it via CF described like here

but that didn't work. Just booted up normally.
Any ideas?
