Recently, when I open NOD32, I get an error msg in the scanning log: "Error occured while scanning MBR sector of the 2. physical disk. Error reading sector." I'm using v2.12.3 with the latest updates, with XP sp2... Athlon XP 1.8gHz... 512k ram... everything's working fine, except this error msg. I have only one hd on this computer, and have NOD set to only scan that drive. I've done all kinds of diagnostics on the hard drive, and it comes up working great. Any ideas Thanks!
