i have an h120 I will be using to record a show tonight. Whenever I test it though it's giving me this message: "WARNING: Low Disk Space". It says this even though I have deleted every song off of the unit! The only thing on there right now is Rockbox and that's it. I've checked that the device is empty both through the computer and through the device. When I plug the device into the computer it's reading it as having 18GB free, but the device itself keeps giving me that Low Disk Space warning... Any ideas? Thanks a lot guys!
