10.6.8 Completely wipe a HD

On a Macbook Pro with 10.6.8. I have an External FW400 drive that I use for backing up my OS drive using Carbon Copy Cloner. I downloaded the latest version of this software, made a backup and the drive now has partition(s) I can't see or access anymore. I wish I didn't update Carbon Cloner because I assume the new options and features, which i was ignorant to, messed things up for me (my assumption).

When I go into Disk Utility it only shows me about 100gb of the 500gb HD. I want to wipe the entire drive as if it was factory default and start my cloning processes all over again. Is it possible I can do this in 10.6.8 with standard practices?

Thanks so much for your time!

Just choose the drive in Disk Utility and then click on the Erase tab, check you have the right format(MacOS Extended Journaled), then click on Erase. That will then wipe the HD ready to start again.

And after that go into Partition and ensure the drive is set up as one single partition, and GUID under Options in Partition.

If one can delete this thread that would be nice...

Thanks for your reply... I'm a bit embarrassed. I was told it was a 500gb HD, I opened up the casing and found it wasn't.

Thanks so much for your time.

:Blushing: What was it then?

It was a 160gb, i guess the HD i was cloning never had more than 160gb of data on it until now... My first post was bonehead material... it figures. Sorry and am most certainly grateful.

Having apple ID issues for over a year which is why I came to your forums here. Over the years when I Google my mac issues your site/forums always came up... hence my visit. Great place and community, Thanks again!
