Hi Everyone,


I've just transferred my data to a new computer and now need to erase the hard drive on my old one.. I've tried Disk Utility, increased the security, and tried 'erase' but I keep getting an error message "couldn't unmount disk". I've gone into Partitions and tried deleting the HD there as well but I get the same message. Does anyone know the solution for this? I just want to get the computer securely wiped and would like to keep Lion as the operating system.


Thanks in advance!
