Why Is Windows Xp Error Check Not Showing A Log After Scanning Drive?

Ok well I connected my external usb drive, went into "my computer", right clicked the drive, chose "tools" tab, clicked on "check now" button for "error checking", and I guess it scanned my drive because it was saying "phase 1, 2, etc". But in the end all it said is "Scan Complete". It didn't list a log of any kind or mention any details about the scan at all. I would assume that means the drive is ok and nothing is wrong? Why is there no log or anything showing what happened during the scan?
