Vmware Workstation - Cannot open disks xxxx or one of the snapshot disks it depends on
Solution 1:
One trick, as per this is to look at the main .vmdk of the guest that is having the problem. For example, in one case that I saw, the guest was using a previously created parent's drive under a new location.
In my case I had the .vmdk mounted in another guest as well and that causes this kind of problem routinely.
So to solve this, for example in my case: in the .vmdk I saw that the parentFileNameHint was set to another location. I then went to this other location, copied the CID and then went back into the problem .vmdk and pasted this CID into the parentCID field that was not correct. After doing this the guest booted right up again.
Solution 2:
Solution to this problem is very elaborate
basically your base image was expanded or is corrupt

if you are not familiar with the instructions mentioned above, walking you though them would be very time consuming and beyond what we can do here on superusers
