Yes, Last evening I installed Norton Power Eraser and ran a scan. Well, to show how ignorant I was, I didn't thoroughly check the files NPE said needed to be removed which were checked by NPE. So like a complete idiot, I clicked the "REMOVE" button. Needless to say, all my CAD files and past drawings were deleted. I attempted a System Restore to restore the deleted files but that didn't work. My AutoCAD program was restored but the files containing the drawings didn't get restored. I then ran Spotmau PowerSuite 2012 File Restore in Advanced Mode but wasn't able to restore these CAD files. So, does anyone have any suggestions on how I might restore these CAD files? I have a great deal of time invested in these drawings, and to be quite honest, time is not on my side to reconstruct these drawings. I was certain System Restore would revert my system back to the state it was prior to the NPE scan and removal. But was I mistaken.
