Hey guys, another bone head questions. I made a thread today regarding macro viruses affecting MS office. Instead of installing a anti virus software, i choose to go to the extremes of just reformatting my computer. I'll start new and fresh. My question is, if i did the 7 pass erase, will the macro (they say its harmless but still..) virus totally be eradicated? If not, restoring via 7 pass would have been a waste of time! Also, wiping an a HD that was previously used for mac os, does not require the disk utility/partition method when reformatting correct? I remember reading that you should use use those steps when you have a brand new HD thats never been formatted. when you use the erase/7 pass method (and not the partition method) will the drive already be set up with the GUID partition table?
