Yes am definitely removing the card correctly ejecting it as should but makes no difference. All files are .mp3. I managed to get a good amount on the SD Card but now have a few more albums to add to it, i have tried adding these using the built in SD card reader/writer on 3 laptops and using USB card reader/writer, tried dragging and dropping, copy and paste, send to, media player sync all copy the new albums fine to the card and can see them fine NOT LINKS, as soon as i take the card out and reinsert the album folders are still there but are empty, i have show hidden files turned on so not just hidden. To repeat this is happening on 3 different laptops, different music, and 3 different SD cards all expensive branded so not junk. I have even removed the DRM from a few albums which worked fine so tried on the new ones but still no joy. Cannot keep reformatting as it takes hours and then more hours to copy back then find out the same problem still exists. Please someone else must have had this issue help before i implode.
