10.4: Use of Access Control Lists causes issues with tar

The tar utility in 10.4 is great in that it now supports copying of resource forks. I've used hfstar for a long while, and thought I'd switch this weekend to using the 10.4 version on a newly-acquired Intel iMac. The machine has its internal disk partitioned into three pieces: OS, Users and Media. On the OS and Media partitions, /usr/bin/tar worked fine and preserved resource forks on the backups.

Just ignore the errors that show up in Terminal; they have to do with the fact that there are some photos in the modified folder (such as movie thumbnails) which don't have corresponding originals.Credit goes to ...

One method of skipping bad sectors on an iPod's drive

I purchesed a 3G iPod (15GB) second-hand for $65, not a bad deal eh? Well, the iPod worked fine until I saw I could not add music past the 10.96GB remaining space mark. I though it was just a formatting error at first, so...
