Solution to The "the parent virtual disk has been modified since The child was created" error on the vmvm

 

The following error occurs recently when a VM is opened:
The parent virtual disk has been modified since the child was created

For example:

I checked the Internet, mainly because of Virtual Disk problems caused by illegal shutdown. When a disk is faulty, in the summary of the virtual machine, the disk size is 0, for example:

Solution:

Select "Edit VM Settings" and select the drive letter of 0 bytes. the following error occurs. Click OK to view the "Disk File" item in the menu, as shown in, this is the configuration file of the problematic virtual disk, for example:

Then open the vmdk virtual disk configuration file (.... 0_0000001.vmdk). Find two options: the first is a line starting with parentCID, and the second is a line starting with parentFileNameHint, for example:

Then, open parentFileNameHint again. The file indicated after the row is the disk configuration file of the parent disk (.... -0. vmdk), for example:

Note that the value of the first line of CID is 812e4778. Under normal circumstances, the value should be the virtual disk configuration file .... Value of parentCID in 0-0000001.vmdk, Which is 9f52a1b2.

The fault is caused by the difference between the value of parentCID in the configuration file of the virtual disk and the value of CID in the file indicated by the first row of the parent disk, that is, parentFileNameHint. So far, The parent virtual disk has been modified since the child was created error will not appear when you open The virtual machine again.
