Windows repairs ntfs drive successfully — can and should I check for corruption?

Occasionally, Windows decides that my very large NTFS drive is "dirty" and needs to be repaired. It does so successfully, but the experience always makes me uncomfortable—are all of my files really still intact? Were any of them modified or deleted?

The files on this drive are backed up once every few days, so I'm not concerned about actually losing (much) data. However, I don't keep old backups indefinitely, so I'd hate for the originals to get silently corrupted without my knowledge.

Short of comparing/checksumming every file on the disk against my backup copy (which would take days to complete), is there any way to check for file corruption? Is it possible to see what files or directories were modified in the Windows repair, so I could just inspect those?

_{Note: I do not believe the drive is failing. These repairs usually occur after sudden shutdowns, or when software on my Mac and Windows partitions doesn't want to play nicely together.}
