Before recovering, understand the two components:

Once the descriptor file is saved in the same directory as the flat file:

RW 83886080 VMFS "MyVM-flat.vmdk"

This method may not directly work if you're trying to point to an existing flat file due to how the tool handles disk conversion.

If you’ve worked with VMware virtual machines, you may have encountered two files: vmname.vmdk (a small descriptor file) and vmname-flat.vmdk (the actual raw data). If the descriptor file is deleted, corrupted, or missing, your virtual machine won’t boot or be recognized by VMware products—even though your data is perfectly safe inside the -flat.vmdk file. how to recover vmdk from flat file

-flat.vmdk file, you must recreate the missing disk descriptor file. In VMware vSphere environments, a virtual disk consists of two distinct components: the large -flat.vmdk file containing the raw binary data, and a tiny companion text file ( .vmdk ) that serves as the disk descriptor. If the descriptor file becomes corrupted or accidentally deleted, the hypervisor displays a "File not found" error and refuses to power on the virtual machine. In VMware vSphere environments, a virtual disk consists
