LRF files work on 1 card but not the other
I have a good sized comic collection in LRF that i read from time to time on the train. If I put these files onto the sony memory card i have, it doesnt even see that the files are there, but if i put them on the sdhc card they work fine.
I am also finding this with certain pdf's as well, they are showing as protected, but if i put them on the sdhc they work fine.
Any ideas? as this is driving me barmy!
