I got a macbook pro and a My Book 1tb. Want to finally put away my old PC (which is running only on UBUNTU) away but I need to get the files off my PC onto the MY BOOK. Well after setting up the time machine and what not I move the HD & connect it to my PC & attempt to drag files onto it.Says it's read only. Tried changing the sharing options to read and write for everyone on my mac. Still the same. Used disk utility to wipe clean the entire HD. Still read only. Posting this on Ubuntu forums but I'm positive the problem is on the Mac. hoping someone knows what the deal is.
