Thank you, I know I am able to power on pointing the .vmx file to the base disk and bypassing the snapshots altogether. I "recovered" one of the other machines I was having issues with this way. Guess I was looking for something like a "diskchk" utility that could be run on a virtual disk that is having problems. My fault for keeping snapshots around. Luckily this is not a critical machine. I can mount a virtual disk from another VM and run utilities that way, but not a delta disk file, at least I have not been able to.
Thanks for the suggestions.
