I guess my hard drive is on its way out. I put a copy of my Roms folder onto my computer c: drive and updated the bad Rom files re·audited the Roms and it came back clean, twice. Did the same thing on my external drive that I keep all my files on and audited it and came up with more bad Rom files. Replaced those and audited again and again new bad Roms popped up. So it seems like it's time for a new drive....
