Hi all. I'll apologize in advance for being noob-ish. I have a black Macbook (late 2006 model, Intel, 160 GB HD, RAM = 2G, I think). Lately it is sluggish at best. I ran the Disk Utility from the Snow Leopard DVD and a few errors were repaired. I have been backing up religiously for several months using Time Machine, and just last week I went ahead and manually moved (in an abundance of caution) all my "personal" folders (itunes, documents, photos...etc.). And, just to make sure all my OCD peculiarities had been alleviated, I went ahead and did a CTRL+click on "Macintosh HD" and copied, then pasted to an external. I feel pretty good about making sure I have everything I want to copy from the drive before I go ahead and wipe it clean. Any more advice I could get would be greatly appreciated. I'm not new to Mac, just new to reformatting a hard drive on one. Also, if anyone knows of any good info regarding the wipe/starting over, I would welcome that as well. Thanks again, and be gentle.
