What does this mean?

At the beginning of all my scans, I get the following message...

"Scan performed at: 2/6/2007 4:00:28 AM
Scanning Log
NOD32 version 2039 (20070205) NT
Command line: /local /adware /ah /all /arch+ /clean /cleanmode /delete /heur+ /log+ /mailbox+ /ntfs+ /pack+ /quarantine /scanboot+ /scanmbr+ /scanmem+ /scroll+ /sfx+ /unsafe /wrap+ /quit+
Operating memory - is OK
Active boot sector of the 1. physical disk - Error reading disk sector
MBR sector of the 2. physical disk - Error reading disk sector"
​

I bolded the section in question. Why is NOD32 reporting errors reading disk sector? Is this normal?

After this message NOD32 goes on to scan all the files on my local drives and reports a completed scan.

 

Please ignore my questions in post above, I finally got off my duff and searched the forum for references to these errors and found my answers. My appologies for any inconveniance

 

Thanks for letting us know and don't worry
