VMware “Cannot open the disk ‘XXXXXX.vmdk’ or one of the snapshot disks it depends on.”
Open the *.vmx file in a text editor and find the line that refers to the old snapshot file, which will look something like:
scsi0:0.fileName = “XXXXXX-000002.vmdk”
ide0:0.fileName = “XXXXXX-000002.vmdk”
Change the value to the filename of the ~1kb .vmdk file (which happens to be the same as the name of the VM).
