    Hi all,

    I have a Mac HDD encrypted with Mcaffee Encryption that I would like to erase. I remember something somewhere about a low level disk wipe that could possible remove this? Does this ring any bells with anyone please? Some information on how to do it would be great!

    Many thanks for your help in advance.

    Kind Regards
    Dave

    Is this an external drive?

    Type "diskutil cs list" (without the quotes) in Terminal and post up the output. Make sure the drive is attached when you do this.

    What happens if you simply erase the drive using Disk Utility?

    Hi guys,

    It is the internal HDD, I have tried the erase via disk utility, but it does not remove the Mcaffee Encryption bootup partitions?

    I believe you need to boot up from another disk (or recovery partition) and then repartition the drive. That should remove the encryption. I believe it works by decrypting the volume at boot up using a boot-loader (I could be wrong on this) but by repartitioning the drive you remove all vestiges of McAfee. In order to do that, you cannot boot up on the existing drive.
