Unrelated BSOD while defragmenting - Problem?

While I was defragmenting, there was a BSOD on a known, unrelated issue.

Does anybody know how Windows defrag works so that whether a BSOD would damage data altogether or whether MS OSes build in some protective mechanism into the defrag process so that file integrity is intact at all times during the defrag process?

Would you happen to know what algorithm they use when moving data around during the defrag procedure?
 
It's possible to loose the cluster(s) that were being manipulated but the MFT should have survived due to journaling. Definately kick off a chkdsk though.
