Ok, so I've done a lot of searching for an answer to this, but I haven't exactly found what I'm looking for. I have a feeling this question has come up before, but here it goes... I have a PC running Windows XP and an external drive attached to it. I have installed Macdrive so that the PC recognizes the HFS+ formatted drive with all of my backups on it, and I also used the terminal command to recognize unsupported drives (com.apple.systempreferences TMShowUnsupportedNetworkVolumes 1). I want to backup my Macbook Pro over my home network via external drive connected to a PC. From what I understand, my PC can't write to HFS+ drives. Is this correct? If it is, is there any way around this? If not, is there any way this setup will work (e.g. formatting the drive to a Windows partition and then having Time Machine write to it that way). Any help or explanation as to why this won't work EVER is appreciated.
