Use your restore/retail disc and reformat the drive. "sudo rm -rf /" will not erase the drive completely.

No, it won't. "rm" is not the same as a reformat, and does not destroy the extant data on the disc. Look it up.

Do you mean once you reinstall the operating system? Yes.

Open up disc utilities. Look for you hard drive and select it then, pick erase and choose the option to zero out, can't remember what it's called but it's the one that overwrites many time by zeroing out the disc. You'll see what I mean when you look. It'll take a long long time but should do the trick but no disc, apart from a smashed up disc, that can't be scoured for recoverable data. The other option is to buy a cheep new hdd and replace the current one with that then use the original as an external drive.


Cheers, Macjim.

I'm seling a MacBook Air. Have the original discs to restore. I then have family packs for the latest O/S, iLife and iWork that were loaded onto it, so yes, I guess I mean reinstall.

Thinking about this a bit more. Are there any tricks I should be aware of in using the restore disc for my MBAir? Obviously no disc drive and I know you use the disc drive from another machine [in my case my iMac] but are there any potential issues?

Thanks
