Recently I downloaded the new Windows 8. In the past I have been able with no problem to transfer songs etc. to my phone disk which is plugged into my "Removable Disk F". Now when I try it, it says " The disk is write protected. Remove the write-protection or use another disk". I never got this before and some of the same songs that I have already tranferred in the past will not tranfer now. Any idea what I need to do to solve this? Thanks for the help.
