I have a g5 ppc running the newest OSX. Somehow my startup folder got corrupted and my computer would not start up. so I did a restore from time machine. The restore worked ok. I have 2 external hard drives attached to my computer, one for time machine and one for iTunes and movies. After restore and restart my computer said the hard drive attatched could not be repaired by disk utility. I did not ask it to fix anything. Now, I don't have permission to write to my external hard drive on the non time machine hard drive. When I get info, the lock on the bottom is not available, and I can't modify anything. Can I fix this by going into the terminal? And how? Or what. Thanks!!
