Which is the better method? I partitioned my HD first via the install disc but then I thought I'd better erase it as well so there is no residual data. However, when I attempt the 35 Pass Secure Erase, it tells me: "Secure Disk Erase failed with the error: Could not open disk".. Is all my data really and completely gone? Or did I just deprive myself (by creating a new partition first) of what could have been a much more thorough erase? I don't want leftover data! Thanks for any insight/help that you guys can provide.
