My T400 (bought last July) harddrive dead on me Sunday. I called helpcenter and received a replacement harddrive today. It was very fast. They asked me to return the old one. I have a concern about the security of my old harddrive. There are lots of personal information (data and files) on the old harddrive. If I return the old one, is there a chance my personal data be leaked? Is there any way I can delete the data and file on the old harddrive? I have no access to my old harddrive now. Any comments and suggestions will be appreciated greatly. Thank you for your time.
