This means fsck does NOT run on the Kubuntu filesystem.

This is the Windows partition.

You never said what the problem was that led you to run fsck in the first
place. By the provided context, I can only assume it was some kind of
Windows problem, in which case, the fsck behavior you observe in Kubuntu
may be dealt with as follows:

1) Boot Windows
2) Run CMD.EXE
3) Type: CHKDSK/F
4) Agree to schedule the check
5) Reboot Windows
6) Boot Windows a couple more times
7) If Kubuntu still wants you to copy the sector after that, do so, if
you're sure you did 1-6 right, otherwise, be prepared to wipe Windows
