Question : Scandisk: (XXXXXXXX.. of XXXXXXX.. USN bytes processed)

Everytime I run scandisk on my Vista Home Premium (scheduled - will run after boot), I'm always getting bellow error. It's a long list error:

39 percent complete. (XXXXXXXX.. of XXXXXXX.. USN bytes processed)
..
..

Where XXX.. is a number eg. 97517568 of 104914048.

Maybe amount of the list around 40 - 50 list.

Anyone know what is this?

I noticed this error after restoring a backup using Norton Save and Restore 2.0.

Answer : Scandisk: (XXXXXXXX.. of XXXXXXX.. USN bytes processed)

If you're getting something like this:

CHKDSK is verifying Usn Journal...
  36040912 USN bytes processed.
Usn Journal verification completed.

that's normal.

But if you're getting errors listed then I assume that there is some corruption on your disc.

The USN is the update sequence number, if the USN journal is corrupt you may need to reformat and reinstall Windows.
