My girlfriend had her apartment broken into recently and her laptop was stolen. She had purchased an external hard drive, but hadnt gotten around to backing up her music prior to the burglary. Anyway, I thought it would nice to load up her external with music, and several of our friends agreed to contribute from their personal collections. Here is my dilemma . One of our friends transferred music onto the external last night from her PC. Now, a different friend is trying to transfer music onto the hard drive from his Mac and is encountering issues. When he drags files over, they wont show up. He cant create new folder on the drive. It asks him if he wants to use it with Mac time machine and he said No. Anyone got an idea what we should do?????? This is a birthday present that I am hoping to surprise her with tonight . Thanks in advance!
