With every on demand scan (whether single file, or entire hard drive), I get the following error: "Error occurred while scanning MBR sector of the 6. physical disk. Error reading sector." This question has been previously asked re MBR sector of the 2. My error is MBR sector of the 6, sometimes 5. Does the answer previously given (see below) also apply to MBR sectors other than 2? Thanks. Answer previously given: http://www.wilderssecurity.com/showthread.php?t=140354 "Hi JR, the MBR error messages you are seeing, relate to: 1. you perform a system scan under the account of a limited user. 2. you have a special boot manager or suchlike program that alters boot sectors installed. 3. you use a card reader while no card is actually inserted."
