How to make Bootcamp data unaccessible?

[peterpan123]

I have been using Windows via bootcamp. As I am returning my rMBP to the company, I don't want them to have access to the files in my Windows partition. What is the best way to do it? Is deleting the bootcamp windows partition good enough? I guess they might have some way to recover the deleted partition.

Use the Boot Camp Assistant from OS X to remove the BC partition. Once that is completed, the partition is not recoverable using normal recovery procedures. But before you do that and from within Windows you might want to remove any files and/or data that you don't want them to have access to. There are Windows programs that will overwrite free space and deleted files making them unrecoverable.

If you're really paranoid, you can enable Bitlocker on your Windows partition

Let it fully encrypt that OS

Then delete all partitions and clean install OSX over everything

You can secure erase the boot camp partition in Mac OS X before proceeding to delete all together which will cause your OS X partition to take up that space.

Easier way would be to erase/format the Windows partition(s) using Disk Utility's 'erase free space' feature to zero-out the deleted data (making it completely unrecoverable). Then delete the partition after that's done.

Just erase it, I doubt anyone in the company will go to the trouble of trying to recover previously deleted data on your MBP.
