I noticed the other day that my hard drive was making a clicking sound. i called apple tech support and they told me i should replace it ASAP. Since my computer is still under warrantee, i thought i would go ahead with it. I went down at apple, and they told me i'd have to pay ~100 to backup my data. But i can just back it up at home, so thats what i'm doing right now. Unfortunately the external drive is a FAT32 drive, and it has many files i can't loose, so I can't use any automatic backup programs. No problem i can just drag all the file there right? The thing is that when i do that, only 58.41GB (out of 65.36GB used) are being copied over. Do i need to see the invisible files and copy those as well? or what should i do?
