Hi there, the problem is that your friend has a Mac and you have a PC; they don’t like each other. Windows uses the NTFS file system while Macs use HFS+, when a hard drive is formatted for one computer, it does not work on the other one.

If your drive works on the Mac but you have access problems on Windows then the hard drive is working as HFS+ right now, so your options are to either format the drive into a way that both computers recognize (Like FAT32, but it will give you a lot of restrictions like not being able to copy files larger than 4GB and you won’t do automatic backups any longer) or install in your PC a program that allows your PC to recognize and work with drives formatted for Macs, a free program like HFSexplore could help you.
