You should run a chdman -verify on the file and report the results.

MAME doesn't scan the file. It loads the header and later on during gameplay it uses the sectormap to find the needed data. If the sectormap is somehow corrupted somewhere you most likely don't see it until you completely played the game. Again, I think a chdman -verify should show you if the chd in question is corrupt or not.

a51mxr3k and area51mx share the same file so you only need it once in the area51mx folder. If cmpro complains about it in the clone you either:
- you're using not-merged sets (then you'd need the file twice)
- don't have the parent enabled
- use a different datfile (better use a direct mame import)
- something went wrong when the parent was scanned (maybe some other tool blocked the access)

Both things sound a bit spooky to me and I think something may interfear with your scan. Maybe a virusscanner (try to turn it of for the roms folder or during scan) or a general fault.
What you can do is: Go to About and drag'n drop the chds in question into the window. Cmpro will report hashvalues for the dropped files and please copy/paste me the results. This will be hashvalues for the files themselves, not for the unpacked chd. But so I can see if your files differ from the commonly available ones.

Since you don't seem to have issues with other chds something's seem to wrong with these 2 or something is spooky on your system. Please gimme some more information about which MAME.exe/datfile you're using, which merge mode, how you stored your files, the cmpro settings etc...(easiest would be to send me cmpro.ini, the settingsfile *.cmp for the used profile for this purposes).
