Hey Bob,
flags 0xa Input/output error (327689)
There is a typo on one of the commands I asked you to run, but then, that's OK as both the snapshots seem to be having errors. As you have mentioned, might have happened during the initial copy.
One other thing you could try out is probably just go to the edit settings of the virtual machine and removing the hard drive (currently it will be pointing to a snapshot file) and pointing it to the base disk and powering on the Virtual Machine.
What that will do is essentially bypass the data (and hopefully corruption) in the snapshot files and allow you to access the base image. This will only work if the data in the base image is intact.
Regards
a
