Speaking of silver linings...
After carelessly clicking the wrong button in TechTool Pro, I had erased everything on my hard drive. Everything! Gone. Since I had just backed up my files, and had a recent backup of my System Folder, it didn't take long to restore many of the "essentials".
The silver lining? Since I can't possibly remember everything I had installed, or where it all was, I have a much leaner machine. I'll just add things as I need them. The stuff that never gets used will not be reinstalled. If I miss it, I'll find it and restore it.
Now, I must go looking for my bookmarks. My address book and old e-mails were restored, so there's hope.
P.S. TTP really should put "Wipe Disk" in an "Advanced" or "Expert" window instead of right near where "Wipe Free Space" is located. I learned my lesson: pay attention!
