I am having trouble writing/deleting data on my external hard drive. My external HD is comprised of the internal HD that I pulled out of my PC with a case on it. I was told that I would be able to use this on my Mac, but so far I haven't had any luck with it. Am I doing something wrong? Is there a way to delete the PC files into my recycle bin? Why can't I add new data to it? Please feel free to chime in on any or all of the questions. Thanks alot...
