    I have a external HD that was used for time machine that I am going to erase because I now have a time capsule. I was able to erase part of the HD but it is still showing 138 out of 500 gigs used. No data is visible when I open it in finder but when I click on info it shows that space is still taken up?

    How do I view the 138 gigs of data?
    How do I delete it?
    If these two things dont work how do I format the HD?

    Thanks

    Have it connected to your Mac and use Disk Utility. Then you can erase and reformat it.
